Intel® Xeon™ W-2155

The Intel Xeon W-2155 is a server processor with 10 cores and 20 threads, built on the Skylake architecture. It launched in Jul 2017. Clocks run from 3.3 GHz base to 4.5 GHz boost. A 13.75-MB L3 cache backs the cores (2.4 MB per core). It addresses DDR4 memory up to 512 GB across 4 channels. The chip drops into the FCLGA2066 socket and exposes PCIe 3.0 (48 lanes). Rated TDP is 140 W. Notable platform capabilities: AVX-512, Extended Page Tables (EPT).

The Intel Xeon W-2155 scores 2,562 in single-core performance and 20,620 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 7,268 for overall performance, 16,990 for productivity performance, 15,953 for creator performance, 21,780 for engineering performance and 12,841 for gaming performance. Its multi-core throughput works out to 2,062 per core, 1,031 per thread and 147 per watt. Its computed efficiency index is 614. Its performance index is 90, so its overall performance is 10% below 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-2155 scores 71,674 in integer math, 44,300 in floating-point math, 308,329 in compression, 7,253 in cryptography, 1,243 in physics simulation, 24,717 in vector SIMD, 75 in the prime sieve and 39,383 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 22% above in integer math, 3% below in floating-point math, 35% above in compression, 37% below in cryptography, 14% above in physics simulation, 59% above in vector SIMD, 12% above in the prime sieve and 74% 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-2155 has 10 physical cores and runs 20 logical threads. It runs 2 threads per core. It runs at a base clock of 3.30 GHz and boosts up to 4.50 GHz.
