INTEL Core Ultra 7 265KF Processor ( 5.50 GHz / 20 Core / 20 Threads )

The Intel Core Ultra 7 265KF is a desktop processor in Intel’s Core Ultra Series 2 (Arrow Lake) family, launched in October 2024. It is designed for the FCLGA1851 socket and requires a compatible 800-series or later motherboard. The processor carries the product code BX80768265KF and targets high-performance desktop builds that pair it with a discrete graphics card, as it carries no integrated GPU. The hybrid core configuration comprises 8 Performance-cores and 12 Efficient-cores, totalling 20 cores and 20 threads. The Performance-cores reach a base clock of 3.9 GHz and a maximum turbo frequency of 5.4 GHz, while the Efficient-cores run at a 3.3 GHz base and boost up to 4.6 GHz. The overall maximum turbo frequency reported by Intel Turbo Boost Max Technology 3.0 is 5.5 GHz. Intel Thread Director works alongside the operating system scheduler to route workloads to the most appropriate core type in real time, helping to balance responsiveness and efficiency across mixed workloads such as gaming alongside background streaming or compilation tasks. The die is fabricated on TSMC’s N3B (3 nm class) node and integrates 17,800 million transistors. chip cache totals 30 MB of Intel Smart Cache (L3) and 36 MB of L2 cache. The processor base power is 125 W, with a maximum turbo power of 250 W; adequate cooling rated to PCG 2020A or above is required, and the maximum operating temperature is 105 °C. Memory support extends to dual-channel DDR5 at speeds up to 6400 MT/s, with a maximum addressable capacity of 192 GB. For connectivity, the chip provides up to 24 PCIe lanes split across PCIe 5.0 and PCIe 4.0 configurations (e.g., 1×16 + 2×4, 2×8 + 2×4, or 1×8 + 4×4), plus a DMI 4 interface with 8 lanes linking to the platform controller. Thunderbolt 4 support is present. An integrated Intel AI Boost NPU delivers 13 TOPS (Int8), contributing to a system-level peak of 25 TOPS (Int8). The NPU supports Windows Studio Effects and frameworks including OpenVINO, WindowsML, DirectML, ONNX Runtime, and WebNN. The CPU itself includes Intel Deep Learning Boost (DL Boost) and supports the same AI software frameworks. The Gaussian & Neural Accelerator version is 3.5. The unlocked multiplier (indicated by the “K” suffix) allows straightforward overclocking. Instruction set extensions include SSE4.1, SSE4.2, and AVX2; AVX-512 is not supported. Hardware virtualisation features include Intel VT-x, VT-d, VT-x with EPT, and IOMMU (PCI passthrough). Security technologies include AES-NI, Intel Trusted Execution Technology, Boot Guard, OS Guard, Control-Flow Enforcement Technology, Execute Disable Bit, Secure Key, and Mode-Based Execute Control.
