Intel® Xeon™ W-1350

The Intel Xeon W-1350 is a workstation processor with 6 cores and 12 threads, built on the Rocket Lake architecture (14 nm process). It launched in Apr 2021. Clocks run from 3.3 GHz base to 5.0 GHz boost. A 12-MB L3 cache backs the cores (2.6 MB per core). It addresses DDR4 memory up to 128 GB across 2 channels. The chip drops into the FCLGA1200 socket and exposes PCIe 4.0 (20 lanes). Rated TDP is 80 W. Notable platform capabilities: Gaussian Neural Accelerator, AVX-512, Extended Page Tables (EPT).

The Intel Xeon W-1350 scores 3,408 in single-core performance and 18,447 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 7,929 for overall performance, 16,762 for productivity performance, 16,280 for creator performance, 18,332 for engineering performance and 14,836 for gaming performance. Its multi-core throughput works out to 3,075 per core, 1,537 per thread and 231 per watt. Its computed efficiency index is 887. Its performance index is 98, so its overall performance is 2% 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-1350 scores 61,660 in integer math, 36,660 in floating-point math, 230,963 in compression, 11,660 in cryptography, 848 in physics simulation, 16,385 in vector SIMD, 52 in the prime sieve and 26,956 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 5% above in integer math, 20% below in floating-point math, 1% above in compression, 1% above in cryptography, 22% below in physics simulation, 6% above in vector SIMD, 22% below in the prime sieve and 19% 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-1350 has 6 physical cores and runs 12 logical threads. It runs 2 threads per core. It runs at a base clock of 3.30 GHz and boosts up to 5.00 GHz.
