Intel® Xeon™ D-1520

The Intel Xeon D-1520 is a server processor with 4 cores and 8 threads. It launched in Mar 2015. Clocks run from 2.2 GHz base to 2.6 GHz boost. A 6-MB L3 cache backs the cores (1.8 MB per core). It supports DDR3L, DDR4 memory. It uses the FCBGA1667 socket. Rated TDP is 45 W.

The Intel Xeon D-1520 scores 1,270 in single-core performance and 4,917 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 2,499 for overall performance, 4,974 for productivity performance, 4,990 for creator performance, 4,733 for engineering performance and 5,039 for gaming performance. Its multi-core throughput works out to 1,229 per core, 615 per thread and 109 per watt. Its computed efficiency index is 373. Its performance index is 31, so its overall performance is 69% 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-1520 scores 18,291 in integer math, 11,543 in floating-point math, 80,500 in compression, 1,758 in cryptography, 500 in physics simulation, 3,938 in vector SIMD, 26 in the prime sieve and 11,968 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 69% below in integer math, 75% below in floating-point math, 65% below in compression, 85% below in cryptography, 54% below in physics simulation, 75% below in vector SIMD, 61% below in the prime sieve and 47% below 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-1520 has 4 physical cores and runs 8 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 2.20 GHz and boosts up to 2.60 GHz.

The Intel Xeon D-1520 is a server processor and belongs to the Intel Xeon D family. It launched in Mar 2015.

The Intel Xeon D-1520 has 256 KB of L1 cache, 1 MB of L2 cache and 6 MB of L3 cache. That adds up to about 7.3 MB of cache, or 1.81 MB per core. Each core has 256 KB of private L2 cache.

The Intel Xeon D-1520 has a 3-level cache hierarchy: L1 at 256 KB, L2 at 1 MB and L3 at 6 MB. L3 is the largest level and makes up about 83% of the cache listed here.

The Intel Xeon D-1520 supports DDR3L, DDR4 memory and runs memory at up to 2,133 MT/s. It does not support DDR5 and LPDDR memory.
