Intel® Xeon™ W-2140B

The Intel Xeon W-2140B is a server processor with 8 cores and 16 threads. It launched in Dec 2017. Clocks run from 3.2 GHz base to 4.2 GHz boost. A 11-MB L3 cache backs the cores (2.4 MB per core). It supports DDR4 memory. It uses the FCLGA2066 socket. Rated TDP is 120 W. Notable platform capabilities: AVX-512.

The Intel Xeon W-2140B scores 2,545 in single-core performance and 17,286 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 6,633 for overall performance, 14,799 for productivity performance, 14,088 for creator performance, 17,718 for engineering performance and 11,957 for gaming performance. Its multi-core throughput works out to 2,161 per core, 1,080 per thread and 144 per watt. Its computed efficiency index is 606. Its performance index is 82, so its overall performance is 18% 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-2140B scores 55,781 in integer math, 33,311 in floating-point math, 267,147 in compression, 6,638 in cryptography, 1,145 in physics simulation, 17,660 in vector SIMD, 62 in the prime sieve and 29,775 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 5% below in integer math, 27% below in floating-point math, 17% above in compression, 42% below in cryptography, 5% above in physics simulation, 14% above in vector SIMD, 7% below in the prime sieve and 31% 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-2140B has 8 physical cores and runs 16 logical threads. It does not use a hybrid performance and efficiency core layout. It runs 2 threads per core. It runs at a base clock of 3.20 GHz and boosts up to 4.20 GHz.

The Intel Xeon W-2140B is a server processor and belongs to the Intel Xeon W family. It launched in Dec 2017.

The Intel Xeon W-2140B has 512 KB of L1 cache, 8 MB of L2 cache and 11 MB of L3 cache. That adds up to about 19.5 MB of cache, or 2.44 MB per core. Each core has 1 MB of private L2 cache.

The Intel Xeon W-2140B has a 3-level cache hierarchy: L1 at 512 KB, L2 at 8 MB and L3 at 11 MB. L3 is the largest level and makes up about 56% of the cache listed here.
