Intel® Xeon™ W-3175X

The Intel Xeon W-3175X is a desktop processor with 28 cores and 56 threads, built on the Skylake architecture. It launched in Oct 2018. Clocks run from 3.1 GHz base to 3.8 GHz boost. A 38.5-MB L3 cache backs the cores (2.4 MB per core). It addresses DDR4 memory up to 512 GB across 6 channels. The chip drops into the FCLGA3647 socket and exposes PCIe 3.0 (48 lanes). Rated TDP is 255 W. Notable platform capabilities: AVX-512, Extended Page Tables (EPT).

The Intel Xeon W-3175X scores 2,555 in single-core performance and 45,520 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 10,784 for overall performance, 33,165 for productivity performance, 29,635 for creator performance, 60,883 for engineering performance and 19,045 for gaming performance. Its multi-core throughput works out to 1,626 per core, 813 per thread and 179 per watt. Its computed efficiency index is 675. Its performance index is 134, so its overall performance is 34% 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-3175X scores 190,199 in integer math, 116,343 in floating-point math, 938,001 in compression, 22,501 in cryptography, 2,543 in physics simulation, 57,617 in vector SIMD, 188 in the prime sieve and 107,091 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 223% above in integer math, 153% above in floating-point math, 311% above in compression, 96% above in cryptography, 133% above in physics simulation, 272% above in vector SIMD, 181% above in the prime sieve and 373% 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-3175X has 28 physical cores and runs 56 logical threads. It runs 2 threads per core. It runs at a base clock of 3.10 GHz and boosts up to 3.80 GHz.
