Intel’s Core Ultra 5 Processor 250KF Plus desktop chip is listed on Amazon India at Rs.26,479 (Lowest Price on August 25, 2026). The MRP price is Rs.30,200.
This is an Arrow Lake part in the Core Ultra Series 2 desktop line, built on TSMC N3B and dropping into the LGA1851 socket on Intel 800 Series chipset motherboards. Key specs highlights include an 18-core layout (6 P-cores and 12 E-cores), a 5.3 GHz maximum turbo frequency, 30MB of Intel Smart Cache, DDR5 support up to 7200 MT/s, and an integrated Intel AI Boost NPU rated at 13 TOPS.
The KF suffix means there is no integrated graphics on this part. A discrete graphics card is required.

What We Like About the Core Ultra 5 250KF Plus
- 18 cores in a Core Ultra 5 tier part: 6 P-cores and 12 E-cores, a core count that used to sit further up the stack.
- 30MB Intel Smart Cache: the full L2 allocation, not a cut-down figure for the tier.
- DDR5 up to 7200 MT/s across two channels: supports up to 256GB of memory.
- PCIe 5.0 and 4.0 with 24 lanes: enough for a Gen 5 graphics card plus multiple Gen 4 NVMe drives.
- Intel AI Boost NPU at 13 TOPS: on-chip AI acceleration, which desktop parts have not historically carried.
Cores, Clocks and Cache
The 250KF Plus runs 18 total cores, split as 6 Performance-cores and 12 Efficient-cores. There are no Low Power Efficient-cores on this part. Hyper-Threading is not supported, so thread count matches core count at 18 threads.
Clock speeds break down by core type:
| Clock | Performance-cores | Efficient-cores |
|---|---|---|
| Max Turbo Frequency | 5.3 GHz | 4.6 GHz |
| Base Frequency | 4.2 GHz | 3.3 GHz |
Overall maximum turbo frequency for the part is 5.3 GHz. Cache is 30MB of Intel Smart Cache, with the total L2 cache also listed at 30MB. Intel Thread Director handles scheduling work across the two core types.
Note that the Amazon listing bullets describe a 24-core configuration at up to 5.5 GHz with 250W maximum turbo power. Those figures describe higher parts in the Core Ultra Series 2 desktop range, not the 250KF Plus. Intel’s specification chart for this processor number lists 18 cores, 5.3 GHz and 159W.
Power and Thermals
| Specification | Value |
|---|---|
| Processor Base Power | 125 W |
| Maximum Turbo Power | 159 W |
| Thermal Solution Specification | PCG 2020A |
| Max Operating Temperature | 105 °C |
Idle States, Enhanced Intel SpeedStep, Intel Speed Shift and thermal monitoring are all supported.
Memory and Platform
The chip pairs with Intel 800 Series chipset motherboards on the FCLGA1851 socket. Memory support runs to DDR5 at up to 7200 MT/s across two channels, with a maximum capacity of 256GB. ECC memory is not supported.
Expansion covers PCI Express 5.0 and 4.0 with a maximum of 24 PCIe lanes. Intel lists the supported configurations as up to 1×16+2×4, 2×8+2×4, or 1×8+4×4. DMI is revision 4 with up to 8 lanes. Thunderbolt 4 is not supported on this part, and scalability is single-socket only.
No Integrated Graphics
The KF designation is literal here. Graphics output is listed as n/a, Xe-core count is 0, Intel Quick Sync Video is not supported, and the number of supported displays is 0. A discrete graphics card is mandatory for any build using this processor.
AI Acceleration
Alongside the CPU cores, the 250KF Plus carries an Intel AI Boost NPU rated at 13 TOPS (Int8), with sparsity support and Windows Studio Effects support. Overall peak platform figure across the silicon is 22 TOPS (Int8).
Both the CPU and the NPU support OpenVINO, WindowsML, DirectML, ONNX Runtime and WebNN. Intel Deep Learning Boost is supported on the CPU side, and the Intel Gaussian and Neural Accelerator is at version 3.5.
Security and Virtualisation
Supported: Intel Threat Detection Technology, Intel Standard Manageability, Intel Secure Key, Control-Flow Enforcement Technology, AES New Instructions, Trusted Execution Technology, Execute Disable Bit, OS Guard, Boot Guard, Mode-based Execute Control, Virtualization Technology (VT-x), VT-x with Extended Page Tables, VT-d and Volume Management Device.
Not supported: Intel Active Management Technology, Remote Platform Erase, One-Click Recovery, Total Memory Encryption Multi Key, Stable IT Platform Program, and VT-rp.
