Intel® Core™ Ultra 7 265F

The Intel Core Ultra 7 265F is a desktop processor with a hybrid 20-core layout (8 performance cores + 12 efficiency cores) and 20 threads, built on the Arrow Lake architecture (Compute Tile 's N3B process). It launched in Jan 2025. Clocks run from 2.4 GHz base to 5.3 GHz boost. A 30-MB L3 cache backs the cores (3.4 MB per core). It addresses DDR5 memory up to 256 GB across 2 channels. The chip drops into the FCLGA1851 socket and exposes PCIe 5.0 (24 lanes). Rated TDP is 65 W. Notable platform capabilities: Gaussian Neural Accelerator, Extended Page Tables (EPT), Control-flow Enforcement (CET).

The Intel Core Ultra 7 265F scores 4,755 in single-core performance and 49,548 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 15,349 for overall performance, 38,863 for productivity performance, 35,810 for creator performance, 60,077 for engineering performance and 26,652 for gaming performance. Its multi-core throughput works out to 2,477 per core, 2,477 per thread and 762 per watt. Its computed efficiency index is 1,904. Its performance index is 190, so its overall performance is 90% above the Intel Core i5-12400 (index 100). Each bar shows the score as a share of a reference ceiling, which is the larger of the 99th-percentile score across the Feex CPU database and a fixed baseline.

Scores for individual PassMark CPU Mark test categories. Higher is better. These are measured test scores, not computed from the single-core and multi-core ratings.

In the individual workload tests the Intel Core Ultra 7 265F scores 138,056 in integer math, 173,782 in floating-point math, 506,513 in compression, 39,457 in cryptography, 3,170 in physics simulation, 39,191 in vector SIMD, 415 in the prime sieve and 62,409 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 134% above in integer math, 279% above in floating-point math, 122% above in compression, 243% above in cryptography, 191% above in physics simulation, 153% above in vector SIMD, 519% above in the prime sieve and 176% above in sorting. Each bar shows the score as a share of that workload's reference ceiling, the larger of the 99th-percentile score across CPUs with a recorded value and a fixed baseline.

The Intel Core Ultra 7 265F has 20 physical cores and runs 20 logical threads. It uses a hybrid layout of 8 performance cores and 12 efficiency cores. It does not support simultaneous multithreading, so its thread count equals its core count. It runs at a base clock of 2.40 GHz and boosts up to 5.30 GHz.

The Intel Core Ultra 7 265F is a desktop processor, belongs to the Intel Core Ultra 7 family, uses the Arrow Lake architecture, carries the codename Arrow Lake and is manufactured on a Compute Tile 's N3B process. It launched in Jan 2025.

The Intel Core Ultra 7 265F has 2 MB of L1 cache, 36 MB of L2 cache and 30 MB of L3 cache. That adds up to about 68.0 MB of cache, or 3.40 MB per core.

The Intel Core Ultra 7 265F has a 3-level cache hierarchy: L1 at 2 MB, L2 at 36 MB and L3 at 30 MB. L2 is the largest level and makes up about 53% of the cache listed here.

The Intel Core Ultra 7 265F supports DDR5 memory, addresses up to 256 GB of memory and uses 2 memory channels. It does not support DDR4 and LPDDR memory. It does not support ECC memory.

The Intel Core Ultra 7 265F does not include integrated graphics, so a discrete graphics card is required for display output.

The Intel Core Ultra 7 265F uses the FCLGA1851 socket, supports PCI Express 5.0 and provides up to 24 PCIe lanes.

The Intel Core Ultra 7 265F has a rated TDP of 65 W.
