Intel® Xeon™ W-3275

The Intel Xeon W-3275 is a workstation processor with 28 cores and 56 threads, built on the Cascade Lake architecture. It launched in Apr 2019. Clocks run from 2.5 GHz base to 4.4 GHz boost. A 38.5-MB L3 cache backs the cores (2.4 MB per core). It addresses DDR4 memory up to 1 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-3275 scores 2,576 in single-core performance and 39,449 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 10,081 for overall performance, 29,248 for productivity performance, 26,334 for creator performance, 52,763 for engineering performance and 17,590 for gaming performance. Its multi-core throughput works out to 1,409 per core, 704 per thread and 192 per watt. Its computed efficiency index is 704. Its performance index is 125, so its overall performance is 25% 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-3275 scores 162,048 in integer math, 99,340 in floating-point math, 726,831 in compression, 16,748 in cryptography, 2,395 in physics simulation, 47,971 in vector SIMD, 170 in the prime sieve and 82,747 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 175% above in integer math, 116% above in floating-point math, 219% above in compression, 46% above in cryptography, 120% above in physics simulation, 209% above in vector SIMD, 154% above in the prime sieve and 265% 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-3275 has 28 physical cores and runs 56 logical threads. It runs 2 threads per core. It runs at a base clock of 2.50 GHz and boosts up to 4.40 GHz.
