Intel® Core™ Ultra 7 265

The Intel Core Ultra 7 265 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 7 265 scores 4,694 in single-core performance and 49,735 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 15,279 for overall performance, 38,899 for productivity performance, 35,803 for creator performance, 60,304 for engineering performance and 26,516 for gaming performance. Its multi-core throughput works out to 2,487 per core, 2,487 per thread and 765 per watt. Its computed efficiency index is 1,895. Its performance index is 189, so its overall performance is 89% 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 7 265 scores 134,743 in integer math, 172,680 in floating-point math, 522,901 in compression, 40,460 in cryptography, 2,925 in physics simulation, 41,471 in vector SIMD, 417 in the prime sieve and 63,831 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 129% above in integer math, 276% above in floating-point math, 129% above in compression, 252% above in cryptography, 168% above in physics simulation, 167% above in vector SIMD, 522% above in the prime sieve and 182% 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 7 265 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 7 265 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 7 265 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 7 265 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.
