Intel® Xeon™ W-3365

The Intel Xeon W-3365 is a workstation processor with 32 cores and 64 threads, built on the Ice Lake architecture. It launched in Jul 2021. Clocks run from 2.7 GHz base to 4.0 GHz boost. A 48-MB L3 cache backs the cores (2.8 MB per core). It addresses DDR4 memory up to 4 GB across 8 channels. The chip drops into the FCLGA4189 socket and exposes PCIe 4.0 (64 lanes). Rated TDP is 270 W. Notable platform capabilities: AVX-512, Extended Page Tables (EPT).

The Intel Xeon W-3365 scores 2,587 in single-core performance and 57,312 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 12,176 for overall performance, 40,875 for productivity performance, 36,178 for creator performance, 80,237 for engineering performance and 22,089 for gaming performance. Its multi-core throughput works out to 1,791 per core, 896 per thread and 212 per watt. Its computed efficiency index is 741. Its performance index is 151, so its overall performance is 51% 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-3365 scores 262,387 in integer math, 154,909 in floating-point math, 863,135 in compression, 43,762 in cryptography, 3,587 in physics simulation, 66,257 in vector SIMD, 264 in the prime sieve and 109,686 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 346% above in integer math, 237% above in floating-point math, 278% above in compression, 281% above in cryptography, 229% above in physics simulation, 327% above in vector SIMD, 294% above in the prime sieve and 384% 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-3365 has 32 physical cores and runs 64 logical threads. It runs 2 threads per core. It runs at a base clock of 2.70 GHz and boosts up to 4.00 GHz.
