Intel® Xeon™ W-3265M

The Intel Xeon W-3265M is a workstation processor with 24 cores and 48 threads, built on the Cascade Lake architecture. It launched in Apr 2019. Clocks run from 2.7 GHz base to 4.4 GHz boost. A 33-MB L3 cache backs the cores (2.4 MB per core). It addresses DDR4 memory up to 2 GB across 6 channels. The chip drops into the FCLGA3647 socket and exposes PCIe 3.0 (64 lanes). Rated TDP is 205 W. Notable platform capabilities: AVX-512, Extended Page Tables (EPT).

The Intel Xeon W-3265M scores 2,665 in single-core performance and 36,104 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 9,809 for overall performance, 27,199 for productivity performance, 24,654 for creator performance, 46,033 for engineering performance and 17,021 for gaming performance. Its multi-core throughput works out to 1,504 per core, 752 per thread and 176 per watt. Its computed efficiency index is 685. Its performance index is 122, so its overall performance is 22% 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 Xeon W-3265M scores 141,616 in integer math, 85,069 in floating-point math, 690,715 in compression, 17,594 in cryptography, 2,059 in physics simulation, 41,686 in vector SIMD, 134 in the prime sieve and 74,725 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 140% above in integer math, 85% above in floating-point math, 203% above in compression, 53% above in cryptography, 89% above in physics simulation, 169% above in vector SIMD, 100% above in the prime sieve and 230% 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 Xeon W-3265M has 24 physical cores and runs 48 logical threads. It runs 2 threads per core. It runs at a base clock of 2.70 GHz and boosts up to 4.40 GHz.
