Intel® Xeon™ D-1587

The Intel Xeon D-1587 is a server processor with 16 cores and 32 threads. It launched in Feb 2016. Clocks run from 1.7 GHz base to 2.3 GHz boost. A 24-MB L3 cache backs the cores (1.7 MB per core). It supports DDR3L, DDR4 memory. It uses the FCBGA1667 socket. Rated TDP is 65 W.

The Intel Xeon D-1587 scores 1,394 in single-core performance and 13,630 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 4,359 for overall performance, 10,811 for productivity performance, 10,006 for creator performance, 15,674 for engineering performance and 7,590 for gaming performance. Its multi-core throughput works out to 852 per core, 426 per thread and 210 per watt. Its computed efficiency index is 541. Its performance index is 54, so its overall performance is 46% 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 D-1587 scores 59,472 in integer math, 38,365 in floating-point math, 266,410 in compression, 4,944 in cryptography, 655 in physics simulation, 12,773 in vector SIMD, 47 in the prime sieve and 31,549 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 1% above in integer math, 16% below in floating-point math, 17% above in compression, 57% below in cryptography, 40% below in physics simulation, 18% below in vector SIMD, 30% below in the prime sieve and 39% 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 D-1587 has 16 physical cores and runs 32 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 1.70 GHz and boosts up to 2.30 GHz.

The Intel Xeon D-1587 is a server processor and belongs to the Intel Xeon D family. It launched in Feb 2016.

The Intel Xeon D-1587 has 512 KB of L1 cache, 2 MB of L2 cache and 24 MB of L3 cache. That adds up to about 26.5 MB of cache, or 1.66 MB per core.

The Intel Xeon D-1587 has a 3-level cache hierarchy: L1 at 512 KB, L2 at 2 MB and L3 at 24 MB. L3 is the largest level and makes up about 91% of the cache listed here.
