Description

Intel Core Ultra 5 225F 10-Core 4.9GHz LGA1851 Processor – DDR5, PCIe 5.0 & AI NPU

The Intel Core Ultra 5 225F is a 10-core desktop processor from Intel Core Ultra Processors Series 2, formerly known by the codename Arrow Lake. Designed for the modern LGA1851 desktop platform, it combines six high-performance P-cores with four power-efficient E-cores, reaches boost frequencies up to 4.9GHz and includes a dedicated Intel AI Boost NPU for supported artificial-intelligence workloads.

The processor provides 10 cores and 10 threads, 20MB Intel Smart Cache, 22MB total L2 cache, support for DDR5 memory up to 6400MT/s and up to 24 processor PCI Express lanes with PCIe 5.0 and PCIe 4.0 support.

The “F” suffix means this processor does not contain integrated Intel graphics. A compatible discrete graphics card is therefore required for normal display output. Motherboard HDMI or DisplayPort connectors cannot provide processor graphics with the Core Ultra 5 225F.

This boxed BX80768225F version is also supplied with Intel's Laminar RM2 thermal solution, providing a complete standard cooling solution for stock operation without requiring an aftermarket CPU cooler for a basic build.

Quick answer: The Intel Core Ultra 5 225F is a 10-core / 10-thread LGA1851 desktop CPU with 6 Performance-cores, 4 Efficient-cores, up to 4.9GHz boost, 20MB Smart Cache, DDR5-6400 support, PCIe 5.0/4.0 connectivity and a 13-TOPS Intel AI Boost NPU. It has a 65W processor base power and 121W maximum turbo power. Because it is an F-series processor, a separate graphics card is required.

10-Core Hybrid Desktop Processor

The Core Ultra 5 225F uses Intel's modern performance hybrid architecture, combining two different types of CPU core within the same processor.

Its ten cores are divided into:

  • 6 Performance-cores
  • 4 Efficient-cores

This allows the processor to balance demanding foreground applications with background and multi-tasking workloads.

What Are Performance-Cores?

Intel Performance-cores, commonly called P-cores, are designed for demanding and latency-sensitive workloads.

They are particularly useful for tasks such as:

  • Gaming
  • Application responsiveness
  • Photo editing
  • Programming
  • Content creation
  • Single-thread-sensitive workloads

The six P-cores in the 225F have a base frequency of 3.3GHz and can boost to a maximum of 4.9GHz.

What Are Efficient-Cores?

The four Efficient-cores, or E-cores, are designed to process background and parallel workloads efficiently.

They can assist with:

  • Background applications
  • System services
  • Multi-tasking
  • Parallel workloads
  • Supporting applications while gaming

The E-cores operate from a 2.7GHz base frequency and can boost up to 4.4GHz.

10 Cores and 10 Threads – Not 14 Threads

The Intel Core Ultra 5 225F provides:

  • 10 physical CPU cores
  • 10 CPU threads

This generation does not use Intel Hyper-Threading on the P-cores, so the thread count is the same as the physical core count.

No Intel Hyper-Threading

Intel officially lists Hyper-Threading Technology: No for the 225F.

This is different from many earlier Intel Core desktop processors where individual P-cores could process two software threads.

Up to 4.9GHz Turbo Frequency

The maximum processor turbo frequency is:

4.9GHz

The individual core specifications are:

  • P-core base: 3.3GHz
  • P-core maximum turbo: 4.9GHz
  • E-core base: 2.7GHz
  • E-core maximum turbo: 4.4GHz

Actual operating frequencies vary dynamically according to workload, temperatures, available power and motherboard configuration.

Intel Turbo Boost Technology 2.0

The Core Ultra 5 225F supports Intel Turbo Boost Technology 2.0.

Turbo Boost automatically raises CPU frequency above its base clock when workload, temperature and electrical conditions allow additional performance.

The advertised 4.9GHz speed is therefore a maximum turbo frequency, not the fixed frequency of every core at all times.

20MB Intel Smart Cache

The processor includes 20MB of Intel Smart Cache.

Cache is high-speed memory located close to the CPU cores and helps reduce the time required to retrieve frequently used data.

This can benefit workloads such as:

  • Gaming
  • Application loading
  • Code compilation
  • Content creation
  • General desktop computing

22MB Total L2 Cache

In addition to the 20MB Intel Smart Cache, Intel specifies 22MB of total L2 cache.

65W Processor Base Power

Intel specifies a 65W processor base power for the Core Ultra 5 225F.

This makes it easier to cool than many higher-power unlocked desktop processors while still allowing the processor to increase power consumption during demanding turbo workloads.

121W Maximum Turbo Power

Maximum turbo power is specified at:

121W

A suitable motherboard, power supply and CPU cooler should therefore be selected for the processor's turbo power behaviour rather than considering only the 65W base-power figure.

Intel Laminar RM2 CPU Cooler Included

The exact Memox product uses Intel boxed order code BX80768225F.

Intel confirms that boxed Core Ultra 5 225F processors are supplied with the Intel Laminar RM2 thermal solution.

This allows the processor to be installed and operated at standard settings without needing to purchase a separate CPU cooler immediately.

Intel Laminar RM2 Construction

Intel specifies the Laminar RM2 with:

  • Aluminium heatsink fins
  • Copper heatsink base/core
  • Intel-validated compatibility

Enthusiast users can still choose an aftermarket LGA1851-compatible cooler if they want lower temperatures, lower noise or a different appearance.

LGA1851 Socket – New Motherboard Required

The Core Ultra 5 225F uses the Intel FCLGA1851 socket.

This is a different socket from LGA1700 used by Intel's 12th, 13th and 14th Generation Core desktop processors.

Not Compatible with LGA1700 Motherboards

The Core Ultra 5 225F cannot be installed in an LGA1700 motherboard.

Although LGA1851 has similar physical dimensions to LGA1700, Intel confirms that the two sockets are electrically and mechanically incompatible for processor installation.

Intel 800-Series Motherboard Platform

Intel Core Ultra desktop processors Series 2 are designed for Intel 800-Series desktop chipsets.

Compatible chipset families include:

  • Intel H810
  • Intel B860
  • Intel Z890
  • Intel Q870
  • Intel W880

For most consumer gaming and home-PC builds, B860 and Z890 are among the most common motherboard choices.

Not Compatible with Intel 600- or 700-Series Motherboards

The Core Ultra 5 225F is not compatible with older platforms such as:

  • Z790
  • B760
  • H770
  • H610
  • Z690
  • B660

A motherboard with the correct LGA1851 socket and supported Intel 800-Series chipset is required.

DDR5 Memory Support

The Core Ultra 5 225F supports DDR5 system memory.

Intel's current ARK specification lists memory speeds of up to:

DDR5-6400 MT/s

Up to 256GB Memory

Intel's current processor specification lists support for up to 256GB of system memory, depending on the motherboard and memory configuration.

The processor provides:

  • 2 memory channels
  • DDR5 support
  • Up to DDR5-6400 official memory speed
  • Maximum memory capacity up to 256GB under the current Intel ARK specification

No DDR4 Support

The LGA1851 Core Ultra desktop platform is designed around DDR5 memory.

DDR4 memory from an older system cannot simply be reused with the Core Ultra 5 225F platform.

Memory Speed Also Depends on the Motherboard

The exact memory speed available depends on factors including:

  • Motherboard chipset
  • Motherboard BIOS
  • DIMM configuration
  • Memory modules
  • Memory overclocking support

DDR5 kits advertised above the processor's standard memory specification may rely on motherboard memory-overclocking features such as Intel XMP.

No ECC Memory Support

Intel lists ECC memory support: No for the Core Ultra 5 225F.

Users specifically building a system that requires validated ECC operation should choose a suitable processor and platform that explicitly supports their required ECC configuration.

PCI Express 5.0 and PCI Express 4.0 Support

The processor supports both:

  • PCI Express 5.0
  • PCI Express 4.0

Intel specifies up to 24 processor PCI Express lanes.

Useful for Modern Graphics Cards and NVMe Storage

The CPU's PCI Express connectivity can be used by compatible motherboards for high-bandwidth hardware including:

  • Discrete graphics cards
  • PCIe 5.0 NVMe SSDs
  • PCIe 4.0 NVMe SSDs
  • High-speed expansion devices

The exact lane allocation depends on the motherboard design.

Motherboard Layout Determines Available PCIe Configuration

Intel lists processor PCI Express configurations including:

  • Up to 1 × 16 + 2 × 4
  • Up to 2 × 8 + 2 × 4
  • Up to 1 × 8 + 4 × 4

Not every motherboard exposes every possible CPU lane configuration, so check the exact motherboard specification if multiple PCIe 5.0 devices are planned.

DMI 4.0 Platform Connection

The processor supports Direct Media Interface 4.0 with up to eight DMI lanes.

DMI connects the processor to the motherboard chipset, carrying data for chipset-connected storage, networking, USB and additional PCI Express devices.

Dedicated Intel AI Boost NPU

One of the major architectural additions in Core Ultra desktop processors is a dedicated Neural Processing Unit, or NPU.

Intel calls its NPU:

Intel AI Boost

The Core Ultra 5 225F provides up to 13 TOPS of NPU AI performance.

What Is an NPU?

An NPU is specialised hardware designed to accelerate compatible artificial-intelligence workloads without relying entirely on the CPU cores or discrete graphics card.

Supported applications can potentially use the NPU for tasks such as:

  • Background removal
  • Camera effects
  • Audio processing
  • Noise suppression
  • Image-processing workloads
  • Local AI inference
  • Other compatible AI features

19 Overall Peak AI TOPS

Intel's current specification lists the Core Ultra 5 225F at:

19 overall peak TOPS for INT8 AI workloads

The dedicated Intel AI Boost NPU contributes up to:

13 NPU TOPS

Important AI TOPS Clarification

The 225F should not be advertised as a 36-TOPS processor.

Intel's current official figures for this exact processor are:

  • NPU Peak: 13 TOPS
  • Overall Peak: 19 TOPS

AI Software Framework Support

Intel lists support for AI software frameworks including:

  • OpenVINO
  • WindowsML
  • DirectML
  • ONNX Runtime
  • WebNN

Actual acceleration depends on whether the application supports the relevant Intel AI hardware.

Intel Deep Learning Boost

The processor supports Intel Deep Learning Boost on the CPU.

This provides instructions designed to accelerate supported AI inference and machine-learning workloads directly on the processor cores.

Intel Gaussian & Neural Accelerator 3.5

Intel also lists Gaussian & Neural Accelerator 3.5, or Intel GNA 3.5.

This technology can assist with selected low-power AI and audio-processing tasks supported by compatible software.

Intel Thread Director

The Core Ultra 5 225F supports Intel Thread Director.

Thread Director provides the operating system with information about workload behaviour so supported operating systems can make better scheduling decisions between Performance-cores and Efficient-cores.

F-Series Processor – No Integrated Graphics

The letter F in Core Ultra 5 225F is particularly important.

Intel confirms that F-series boxed desktop processors such as the 225F do not contain Intel processor graphics.

A Dedicated Graphics Card Is Required

For a normal desktop PC that requires monitor output, the system must contain a compatible discrete graphics card.

Examples include graphics cards from:

  • NVIDIA GeForce
  • AMD Radeon
  • Intel Arc

Motherboard HDMI and DisplayPort Will Not Provide CPU Graphics

Even if an LGA1851 motherboard has HDMI or DisplayPort connectors, those motherboard outputs require a processor with compatible integrated graphics.

Because the 225F has no integrated GPU, connect the monitor to the installed discrete graphics card instead.

No Intel Quick Sync Video

The 225F also does not provide Intel Quick Sync Video.

Quick Sync relies on Intel's integrated graphics media engine, which is absent from this F-series CPU.

Users who specifically need Intel integrated graphics or Quick Sync should consider the Core Ultra 5 225 rather than the 225F.

Core Ultra 5 225F vs Core Ultra 5 225

The Core Ultra 5 225 and 225F have very similar CPU specifications, including the same:

  • 10-core design
  • 6 P-cores + 4 E-cores
  • 10 threads
  • 4.9GHz maximum turbo frequency
  • 20MB Smart Cache
  • 22MB L2 cache
  • 65W base power
  • 121W maximum turbo power
  • LGA1851 platform

The key difference is graphics:

  • Core Ultra 5 225: includes Intel Graphics
  • Core Ultra 5 225F: no integrated graphics

The 225F is therefore most appropriate for systems that will definitely use a discrete graphics card.

Core Ultra 5 225F vs Core Ultra 5 245

The 225F should not be confused with higher-tier Core Ultra 5 processors such as the 245.

The 225F has:

  • 10 cores
  • 6 P-cores
  • 4 E-cores
  • 10 threads
  • Up to 4.9GHz
  • 20MB Smart Cache

Higher Core Ultra 5 models can provide additional E-cores, cache and clock speed.

This distinction is important because specifications for a Core Ultra 5 245 or 245K should not be copied onto a 225F product page.

Locked Non-K Processor

The Core Ultra 5 225F is a non-K processor.

It is not designed as Intel's fully multiplier-unlocked overclocking model.

Users specifically seeking CPU core-ratio overclocking should choose a suitable unlocked K-series processor together with an appropriate motherboard and cooling configuration.

B860 Motherboard Compatibility

The Core Ultra 5 225F is officially listed as compatible with Intel's B860 chipset.

B860 can be a particularly suitable match for users building a mainstream Core Ultra gaming or general-purpose desktop because CPU multiplier overclocking is not a core requirement for this locked processor.

Exact motherboard features vary by model.

Z890 Motherboard Compatibility

The processor can also be used with compatible Z890 LGA1851 motherboards.

Z890 boards may provide additional connectivity, expansion, storage and memory-tuning capabilities, depending on the exact motherboard.

H810 Motherboard Compatibility

Intel's entry-level H810 chipset is also part of the Series 2 desktop platform.

H810 boards can suit simpler builds where fewer expansion and tuning features are required.

Wi-Fi Is Motherboard Dependent

The Core Ultra 5 225F itself should not be described as automatically including Wi-Fi 7 or Wi-Fi 6E.

Wireless networking capability depends on the motherboard and installed network hardware.

A compatible B860 or Z890 motherboard may include Wi-Fi 7, but another motherboard may provide no Wi-Fi at all.

Thunderbolt and USB Connectivity Are Platform Dependent

Intel's processor specification does not list integrated Thunderbolt 4 support on the Core Ultra 5 225F itself.

Available Thunderbolt, USB4 and high-speed USB connectivity depends on the motherboard, chipset and any additional controllers implemented by the motherboard manufacturer.

Always check the exact motherboard specification if Thunderbolt or USB4 is required.

Suitable for Mainstream Gaming PCs

The Core Ultra 5 225F can be used as the processor in a modern discrete-GPU gaming PC built around the LGA1851 platform.

Its six Performance-cores handle latency-sensitive workloads while four Efficient-cores provide additional capacity for background applications.

A gaming system based on the 225F will also require:

  • LGA1851 motherboard
  • DDR5 memory
  • Discrete graphics card
  • Compatible power supply
  • Storage
  • Suitable case

Gaming Performance Depends Heavily on the Graphics Card

The processor is only one component in gaming performance.

Actual frame rates also depend on:

  • Graphics card
  • Game engine
  • Resolution
  • Graphics settings
  • Memory speed
  • Cooling

The lack of integrated graphics does not reduce the performance of a compatible discrete GPU; it simply means a discrete GPU is mandatory for display output.

Suitable for Everyday Productivity

The 10-core hybrid design can also handle everyday workloads including:

  • Web browsing
  • Microsoft Office
  • Programming
  • Photo editing
  • Light content creation
  • Multi-tasking
  • General desktop applications

Suitable for AI-Enabled Desktop Applications

The dedicated Intel AI Boost NPU provides hardware specifically designed for supported AI workloads.

This can allow compatible applications to process certain AI features on dedicated hardware rather than placing every workload on the main CPU cores.

NPU Support Is Application Dependent

Simply having an NPU does not automatically accelerate every application.

The software must support Intel's AI hardware or a compatible framework such as OpenVINO, WindowsML, DirectML or ONNX Runtime.

Maximum Operating Temperature of 105°C

Intel specifies a maximum operating temperature of:

105°C

This figure is an operating limit rather than a recommended everyday target temperature.

Correct cooler installation, thermal interface contact and case airflow remain important for maintaining appropriate temperatures.

Processor Package Size

The LGA1851 processor package measures approximately:

45 × 37.5mm

Only use motherboards designed for FCLGA1851.

Important: A Graphics Card Is Required

The Core Ultra 5 225F has no integrated graphics processor.

A compatible discrete graphics card is required if the PC needs monitor output.

Do not purchase this F-series processor expecting to use the motherboard's HDMI or DisplayPort connectors without a discrete GPU.

Important: The 225F Has 10 Threads

The correct specification is:

  • 10 cores
  • 10 threads
  • 6 P-cores
  • 4 E-cores

The processor does not have 14 threads, and it does not have eight E-cores.

Important: The Maximum Frequency Is 4.9GHz

The correct maximum turbo frequency for the 225F is 4.9GHz.

Figures such as 5.2GHz relate to different Core Ultra models and should not be used for this processor.

Important: Correct AI Performance

Intel's official specification for the 225F is:

  • Intel AI Boost NPU: 13 TOPS
  • Overall Peak INT8 AI Performance: 19 TOPS

A 36-TOPS figure does not apply to the Core Ultra 5 225F.

Important: LGA1851 Only

The Core Ultra 5 225F requires an LGA1851 motherboard.

It is not compatible with older LGA1700 motherboards even though the two socket generations have similar physical dimensions.

This platform uses DDR5 memory. DDR4 is not supported by the Core Ultra Series 2 LGA1851 desktop platform.

Important: 800-Series Chipset Platform

Core Ultra Series 2 desktop processors are paired with Intel 800-Series desktop chipsets such as H810, B860 and Z890.

They are not compatible with older Intel 600-Series and 700-Series desktop chipsets.

Important: Wi-Fi and Thunderbolt Are Motherboard Features

Wi-Fi 7, Wi-Fi 6E, Thunderbolt and USB4 should not be advertised as guaranteed processor features of the Core Ultra 5 225F.

Availability depends on the selected motherboard and its integrated controllers.

Important: Maximum Memory Specification

Intel's current ARK product page lists a maximum memory capacity of 256GB for the Core Ultra 5 225F.

Some earlier Intel Series 2 marketing material listed 192GB. For current product-page data, the latest processor-specific Intel ARK specification should take priority.

Who Is the Intel Core Ultra 5 225F Best For?

  • New LGA1851 desktop PC builds
  • Gaming PCs using a discrete graphics card
  • Mainstream B860 gaming systems
  • Z890 desktop builds
  • DDR5-based systems
  • Users wanting a 10-core hybrid Intel CPU
  • Users wanting a dedicated Intel AI Boost NPU
  • Home and office desktops
  • Programming PCs
  • General productivity systems
  • Users who do not need integrated Intel graphics
  • Builders wanting an included Intel boxed CPU cooler

Who Should Consider a Different Processor?

A different CPU may be more appropriate if you specifically need:

  • Integrated graphics without buying a separate GPU
  • Intel Quick Sync Video
  • More than 10 CPU cores
  • Higher multi-core performance
  • An unlocked multiplier for CPU overclocking
  • Compatibility with an existing LGA1700 motherboard
  • DDR4 memory support
  • ECC memory support

If integrated graphics are important, consider the Intel Core Ultra 5 225 rather than the 225F.

Why Choose the Intel Core Ultra 5 225F?

The Intel Core Ultra 5 225F provides an accessible entry point to Intel's LGA1851 Core Ultra desktop platform for builders who already intend to use a discrete graphics card.

Its hybrid configuration combines six Performance-cores and four Efficient-cores for a total of ten physical CPU cores, while maximum turbo frequency reaches 4.9GHz.

The processor includes 20MB Intel Smart Cache and 22MB L2 cache, supports DDR5 memory up to 6400MT/s and provides modern PCI Express 5.0/4.0 connectivity with up to 24 processor PCIe lanes.

A dedicated Intel AI Boost NPU rated at 13 TOPS adds hardware acceleration for supported AI workloads, while Intel Deep Learning Boost provides additional CPU-based AI acceleration.

The 65W processor base power and 121W maximum turbo power make it easier to cool than many higher-power enthusiast CPUs, and Intel supplies the boxed BX80768225F with the Laminar RM2 thermal solution.

The absence of integrated graphics can also make the 225F a logical choice for builds where a discrete NVIDIA, AMD or Intel graphics card will always be installed and integrated graphics would not be used.

Choose the Intel Core Ultra 5 225F if you want a 10-core LGA1851 desktop processor with DDR5-6400 support, PCIe 5.0 connectivity, dedicated NPU acceleration and an included Intel cooler for a modern discrete-GPU PC build.

Important Thread Count Correction

The Intel Core Ultra 5 225F has 10 cores and 10 threads.

The correct configuration is:

  • 6 Performance-Cores
  • 4 Efficient-Cores
  • 10 total cores
  • 10 total threads

Intel officially lists Hyper-Threading Technology: No. A 14-thread figure does not apply to this processor.

Important Efficient-Core Correction

The 225F has 4 Efficient-Cores, not 8.

Specifications showing 6 P-Cores + 8 E-Cores belong to a different Intel Core Ultra processor and should not be used for the 225F.

Important Maximum Frequency Note

The maximum turbo frequency is 4.9GHz.

This is the maximum single-core turbo frequency available under suitable power, temperature and workload conditions. The processor does not run all cores continuously at 4.9GHz.

Important Memory Capacity Correction

Intel's current processor-specific ARK specification lists a maximum supported memory capacity of 256GB.

Older Intel platform documentation and distributor feeds may still list 192GB. For current product information, the newer Intel ARK figure of 256GB should be used.

Important ECC Memory Correction

Intel's current ARK specification lists:

ECC Memory Supported: No

The current Memox source data showing ECC support as Yes should therefore be corrected.

Important Graphics Card Requirement

The F suffix identifies this processor as a model without Intel processor graphics.

The Core Ultra 5 225F provides:

  • No integrated Intel GPU
  • 0 Xe-Cores
  • 0 processor-driven displays
  • No Intel Quick Sync Video

A compatible discrete graphics card is required for normal monitor output.

Important Motherboard Video Output Note

Connecting a monitor to the motherboard's HDMI or DisplayPort connector will not provide processor-generated video with the 225F.

The display should be connected to a compatible discrete graphics card installed in the system.

Important AI Performance Correction

The current Intel specification for the Core Ultra 5 225F is:

  • Intel AI Boost NPU: 13 TOPS INT8
  • Overall Peak AI Performance: 19 TOPS INT8

A 36-TOPS specification does not apply to the Core Ultra 5 225F.

Important LGA1851 Compatibility Note

The Core Ultra 5 225F requires an LGA1851 motherboard.

It is not compatible with LGA1700 motherboards used by many Intel 12th, 13th and 14th Generation desktop processors.

Important DDR5 Compatibility Note

The Core Ultra 5 225F supports DDR5 memory up to DDR5-6400 under Intel's official specification.

DDR4 is not supported on this processor platform.

Important Memory Speed Note

The advertised DDR5-6400 specification is Intel's official processor memory support.

Higher advertised memory-kit speeds may rely on motherboard memory overclocking, Intel XMP profiles, BIOS support and the characteristics of the installed memory configuration.

Important PCIe Lane Note

Intel specifies up to 24 processor PCI Express lanes with PCIe 5.0 and PCIe 4.0 support.

The exact way these lanes are assigned to graphics slots and M.2 SSD sockets depends on the motherboard design.

Important Thunderbolt Note

Intel ARK lists Intel Thunderbolt 4: No for the processor itself.

An LGA1851 motherboard may still provide Thunderbolt or USB4 through its chipset or additional controllers. Do not advertise Thunderbolt as an automatic feature of the 225F itself.

Important Wi-Fi Note

The Core Ultra 5 225F processor does not itself guarantee Wi-Fi 7, Wi-Fi 6E or Bluetooth connectivity.

Wireless networking depends on the selected motherboard and installed network hardware.

Important CPU Cooler Note

The exact BX80768225F retail-boxed SKU includes Intel's Laminar RM2 thermal solution.

Intel rates the Laminar RM2 cooler for 65W TDP support. The processor itself can reach a maximum turbo power of 121W, so users seeking lower temperatures, lower noise or sustained high-load turbo operation may choose a higher-performance LGA1851-compatible aftermarket cooler.

Important 65W vs 121W Power Note

The Core Ultra 5 225F has:

  • 65W Processor Base Power
  • 121W Maximum Turbo Power

The 65W figure should not be interpreted as an absolute maximum power-consumption limit during turbo operation.

Important Operating Temperature Note

Intel lists a maximum operating temperature of 105°C.

This is a processor operating limit, not a recommended normal target temperature. Correct cooler installation, thermal-interface contact and case airflow remain important.

Important Boxed vs Tray Processor Note

These specifications and package contents apply to the boxed BX80768225F SKU.

Intel also manufactures tray/OEM versions of the Core Ultra 5 225F with different ordering codes and warranty arrangements. Do not assume tray processor package contents or warranty terms are identical to the boxed version sold on this page.

Important Warranty Note

Intel generally provides a 3-year limited warranty for eligible authentic boxed Intel processors sold as standalone components.

The included Intel Laminar thermal solution also carries a three-year warranty. Warranty eligibility remains subject to Intel's current terms, serial/batch identification and proof-of-purchase requirements.

Important Barcode Note

The barcode 5032037282376 is a 13-digit EAN / GTIN-13.

It should not be described as a 12-digit UPC.

Model Identification Note

These specifications apply specifically to the Intel Core Ultra 5 Processor 225F, boxed order code BX80768225F, Memox SKU PRINT-U5-225F and EAN / GTIN-13 5032037282376.

14. Can I use a Z790, B760, Z690, B660 or H610 motherboard?

No. Those Intel 600-series and 700-series motherboards use LGA1700. The Core Ultra 5 225F requires an LGA1851 motherboard based on a compatible Intel 800-series platform.

15. Which motherboard chipsets support the Core Ultra 5 225F?

Intel currently lists compatible 800-series options including H810, B860, Z890, Q870 and W880. For consumer gaming PCs, H810, B860 and Z890 are the most common choices.

16. Is B860 a good motherboard chipset for the Core Ultra 5 225F?

Yes. B860 is one of the strongest mainstream matches for the locked 225F. It offers more chipset connectivity than H810 and supports memory overclocking/XMP while avoiding the additional cost of enthusiast Z890 boards where full CPU overclocking capability is less relevant to a locked processor.

17. Will the Core Ultra 5 225F work with H810 motherboards?

Yes. H810 is officially compatible and can make sense for an affordable build. However, H810 provides fewer chipset I/O resources and does not officially support memory overclocking, so B860 may be the better choice when expansion and faster XMP memory matter.

18. Will the Core Ultra 5 225F work with a Z890 motherboard?

Yes. Z890 is compatible and offers the richest consumer 800-series feature set, including more chipset connectivity and overclocking capabilities. Because the 225F itself is locked, a Z890 board is normally chosen for its connectivity and premium features rather than CPU multiplier overclocking.

19. H810 vs B860 vs Z890 – which motherboard should I choose for a 225F?

Choose H810 for a basic budget build with modest expansion needs. Choose B860 for the best mainstream balance of memory tuning, storage, connectivity and price. Choose Z890 if you specifically want premium I/O, additional PCIe/storage options or plan to use a higher-end unlocked LGA1851 processor later.

20. Will I need to update my motherboard BIOS for the 225F?

Many current 800-series boards should support the 225F, but BIOS compatibility always depends on the exact motherboard model and firmware version. Check the manufacturer's CPU Support List before assembly and update the BIOS if the board vendor specifies a required version.

21. What type of RAM does the Core Ultra 5 225F use?

The processor uses DDR5 desktop memory.

22. Can I use DDR4 memory with the Core Ultra 5 225F?

Intel specifies support for memory speeds up to DDR5-6400MT/s in supported configurations.

24. Can I use DDR5-6000 RAM with the Core Ultra 5 225F?

Yes. DDR5-6000 is well within the type of memory commonly used with the platform. Whether a particular kit runs at its advertised profile depends on the motherboard, memory modules, DIMM configuration and BIOS settings.

25. Can I use DDR5 faster than 6400MT/s?

Potentially through memory overclocking on a suitable motherboard such as B860 or Z890. DDR5-6400 is Intel's official processor specification; speeds above that are overclocked configurations and are not guaranteed on every CPU, motherboard or memory kit.

26. Does B860 support XMP and memory overclocking?

Intel officially lists memory overclocking support on B860. A compatible XMP memory kit can therefore be configured above standard JEDEC speeds where the motherboard and CPU memory controller support the profile.

27. Does H810 support memory overclocking?

No. Intel's current 800-series chipset specification does not list memory overclocking support for H810.

28. How much RAM can the Core Ultra 5 225F support?

Intel's current processor-specific ARK specification lists up to 256GB of DDR5 memory, subject to motherboard and DIMM support.

29. Why do some older specifications say the 225F supports only 192GB RAM?

Older Intel Series 2 marketing documents were published with a 192GB platform figure. Intel's current processor-specific ARK page now lists a maximum of 256GB. For current product specifications, the processor-specific ARK figure should take priority.

30. Should I use one DDR5 stick or two?

For a gaming or productivity build, a matched two-DIMM dual-channel configuration is normally preferable. For example, 2 × 16GB is generally better than 1 × 32GB when capacity is the same because both memory channels can be used.

31. Does the Core Ultra 5 225F support ECC RAM?

No. Intel's processor-specific specification lists ECC memory as unsupported on the 225F.

32. Does the Intel Core Ultra 5 225F have integrated graphics?

No. The “F” suffix identifies this version as having no usable integrated processor graphics.

33. Do I need a graphics card with the Core Ultra 5 225F?

Yes. A compatible discrete NVIDIA GeForce, AMD Radeon or Intel Arc graphics card is required if the PC needs display output.

The motherboard display connectors depend on a CPU with integrated graphics. Because the 225F has no integrated GPU, connect the monitor directly to your discrete graphics card.

35. Does the Core Ultra 5 225F support Intel Quick Sync Video?

No. Intel officially lists Quick Sync Video as unavailable because the 225F does not contain active integrated graphics. Users relying heavily on Intel Quick Sync encoding should consider the non-F Core Ultra 5 225 instead.

36. Is the Core Ultra 5 225F good for an RTX 5060 or RTX 5060 Ti gaming PC?

Yes. The 225F is a sensible modern processor for mainstream discrete-GPU gaming builds using graphics cards such as the RTX 5060 or 5060 Ti. Exact performance depends on game, resolution, graphics settings and memory configuration.

37. Is the Core Ultra 5 225F a good match for an RTX 5070?

Yes, particularly for 1440p gaming. Current PC builders are actively using or considering this combination. In very CPU-heavy games or very high-refresh 1080p gaming, a faster CPU can deliver higher maximum frame rates, but the 225F remains a viable RTX 5070 platform.

38. Can I use the Core Ultra 5 225F with an Intel Arc B580?

Yes. A discrete Intel Arc GPU can be used with the 225F, and Intel's own community discussions include real systems combining a Core Ultra 5 225F, B860 motherboard and Arc B580.

39. Can I use AMD Radeon graphics with the 225F?

Yes. The processor can be paired with compatible PCI Express Radeon graphics cards. GPU compatibility is not restricted to Intel or NVIDIA products.

40. Will the Core Ultra 5 225F bottleneck my graphics card?

There is no universal bottleneck percentage. CPU limitations depend on the game, GPU, resolution, graphics settings and frame-rate target. CPU limits are more noticeable in competitive high-refresh 1080p gaming, while 1440p and 4K workloads are often more GPU-limited.

41. Is the Intel Core Ultra 5 225F good for 1080p gaming?

Yes for mainstream gaming. Independent benchmarks show it capable of strong 1080p performance, although faster gaming-focused processors can deliver higher frame rates in CPU-limited titles.

42. Is the Core Ultra 5 225F good for 1440p gaming?

Yes. At 1440p the graphics card generally carries more of the workload, making the 225F a reasonable partner for cards such as the RTX 5060 Ti and RTX 5070 in balanced gaming builds.

43. Is the Core Ultra 5 225F good for coding and productivity?

Yes. Its six Performance-cores and four Efficient-cores make it suitable for programming, office applications, multitasking, software development, web work and general productivity. Heavily threaded professional workloads may benefit from higher-tier Core Ultra processors with more E-cores.

44. Is the 225F good for streaming and video editing?

It can handle mainstream editing and streaming workloads, especially when paired with a modern GPU that provides hardware video encoding. However, because the 225F lacks integrated graphics, it does not provide Intel Quick Sync Video. The non-F 225 can be more useful where Quick Sync is specifically required.

45. Does the Core Ultra 5 225F have an NPU?

Yes. It includes a dedicated Intel AI Boost Neural Processing Unit for supported local AI workloads.

46. How powerful is the Intel AI Boost NPU in the 225F?

Intel specifies up to 13 TOPS of INT8 NPU performance.

47. What is the total AI performance of the Core Ultra 5 225F?

Intel currently specifies approximately 19 overall peak INT8 TOPS for this processor when its supported compute engines are considered. Do not confuse this with higher Core Ultra mobile processors or other desktop SKUs that have different AI figures.

48. Is the Core Ultra 5 225F a Microsoft Copilot+ PC processor?

The processor contains an NPU, but its 13-TOPS NPU does not by itself meet Microsoft's 40+ TOPS NPU requirement for Copilot+ PC-class AI features. It can still accelerate supported AI applications through its CPU and NPU.

49. Does the Core Ultra 5 225F support Windows Studio Effects?

Intel lists Windows Studio Effects support for the processor's NPU. Feature availability still depends on the Windows version, drivers and supported applications.

Yes where the selected motherboard routes suitable CPU PCIe 5.0 lanes to the required slot. Not every H810, B860 or Z890 motherboard provides identical slot wiring, so check the exact motherboard specification before assuming a particular M.2 or graphics slot operates at Gen5 speeds.

54. Does the boxed Core Ultra 5 225F include a CPU cooler?

Yes. The boxed BX80768225F version sold on this page includes Intel's Laminar RM2 thermal solution.

55. Is the Intel Laminar RM2 cooler good enough for the 225F?

It is Intel's supplied thermal solution and is suitable for standard operation in a case with reasonable airflow. The RM2 is rated as a 65W-class cooler, while the CPU can reach 121W maximum turbo power, so an aftermarket tower cooler can provide lower temperatures and quieter operation under prolonged heavy loads.

56. Why can the Core Ultra 5 225F reach around 80°C with the stock cooler?

The compact stock cooler may need to run at high fan speed during CPU-heavy gaming or productivity workloads. Current 225F owners report temperatures around the 80°C range under demanding loads with the stock cooler. Check cooler installation and case airflow first; a larger tower cooler can reduce temperature and noise if desired.

57. Can I reuse an LGA1700 CPU cooler on LGA1851?

Often yes. Intel confirms that LGA1700 and LGA1851 use mounting holes in the same locations, making LGA1700 thermal solutions mechanically compatible with LGA1851. You should still check the cooler manufacturer's thermal and contact compatibility for the exact cooler.

58. Is the Core Ultra 5 225F unlocked for CPU overclocking?

No. The 225F is a non-K processor and is not Intel's fully multiplier-unlocked model. Buyers who specifically want CPU ratio overclocking should choose an appropriate K-series processor and compatible motherboard.

59. Core Ultra 5 225F vs Core Ultra 5 225 – what is the difference?

The CPU specifications are essentially the same: both have 10 cores, 10 threads, up to 4.9GHz, 20MB Smart Cache, 65W base power and 121W maximum turbo power. The major difference is graphics: the Core Ultra 5 225 includes Intel Graphics and Quick Sync, while the 225F has no integrated graphics. Choose the 225F when you will always use a discrete GPU; choose the 225 when integrated display output or Quick Sync is useful.

60. Core Ultra 5 225F vs Core Ultra 5 245K – which should I choose?

The 225F is the lower-power, lower-cost option with 10 cores, 10 threads, up to 4.9GHz and an included cooler. The 245K is a higher-performance unlocked model with 14 cores / 14 threads, 6 P-cores + 8 E-cores, up to 5.2GHz, more cache and substantially higher power limits. Choose the 225F for value-focused mainstream builds; choose the 245K when stronger multi-core performance and CPU overclocking capability justify the additional cost and cooling requirements.

61. Core Ultra 5 225F vs Core i5-14400F – what is the difference?

Both have a 6P + 4E hybrid layout, but they belong to different platforms. The Core i5-14400F uses LGA1700, supports DDR4 or DDR5 and has 10 cores / 16 threads through Hyper-Threading. The 225F uses LGA1851, DDR5 only, 10 cores / 10 threads, up to 4.9GHz, a much larger 22MB L2 cache, 24 CPU PCIe lanes and a dedicated Intel AI Boost NPU. Choose based on platform cost, motherboard/RAM reuse and the features you need rather than core count alone.

62. Core Ultra 5 225F vs Ryzen 5 9600X – which should I choose?

The two CPUs target similar mainstream gaming builds but use very different platforms. The 225F offers 10 hybrid cores, LGA1851, an included Intel cooler and a dedicated 13-TOPS NPU. The Ryzen 5 9600X uses AM5, has 6 Zen 5 cores / 12 threads, integrated basic Radeon graphics, up to 5.4GHz and is multiplier unlocked. Independent gaming testing generally places the 9600X ahead in CPU-limited gaming, while the 225F can be attractive when its processor + motherboard bundle is competitively priced. Consider total platform cost and future upgrade priorities rather than CPU price alone.

63. Does the Core Ultra 5 225F support Windows 11?
