Intel® Xeon™ D-1527

The Intel Xeon D-1527 is a server processor with 4 cores and 8 threads. It launched in Nov 2015. Clocks run from 2.2 GHz base to 2.7 GHz boost. A 6-MB L3 cache backs the cores (1.7 MB per core). It supports DDR3L, DDR4 memory. It uses the FCBGA1667 socket. Rated TDP is 35 W.

The Intel Xeon D-1527 scores 1,460 in single-core performance and 4,948 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 2,688 for overall performance, 5,260 for productivity performance, 5,349 for creator performance, 4,762 for engineering performance and 5,617 for gaming performance. Its multi-core throughput works out to 1,237 per core, 619 per thread and 141 per watt. Its computed efficiency index is 454. Its performance index is 33, so its overall performance is 67% 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-1527 scores 16,655 in integer math, 10,751 in floating-point math, 71,680 in compression, 1,390 in cryptography, 390 in physics simulation, 4,254 in vector SIMD, 22 in the prime sieve and 9,209 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 72% below in integer math, 77% below in floating-point math, 69% below in compression, 88% below in cryptography, 64% below in physics simulation, 73% below in vector SIMD, 67% below in the prime sieve and 59% 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-1527 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 2.70 GHz.

The Intel Xeon D-1527 is a server processor and belongs to the Intel Xeon D family. It launched in Nov 2015.

The Intel Xeon D-1527 has 128 KB of L1 cache, 512 KB of L2 cache and 6 MB of L3 cache. That adds up to about 6.6 MB of cache, or 1.66 MB per core.

The Intel Xeon D-1527 has a 3-level cache hierarchy: L1 at 128 KB, L2 at 512 KB and L3 at 6 MB. L3 is the largest level and makes up about 91% of the cache listed here.
