Intel® Xeon™ E5-2660 v3

The Intel Xeon E5-2660 v3 is a server processor with 10 cores and 20 threads, built on the Haswell architecture. It launched in Jul 2014. Clocks run from 2.6 GHz base to 3.3 GHz boost. A 25-MB L3 cache backs the cores (2.8 MB per core). It addresses DDR4 memory up to 768 GB across 4 channels. The chip drops into the FCLGA2011 socket and exposes PCIe 3.0 (40 lanes). Rated TDP is 105 W. Notable platform capabilities: Extended Page Tables (EPT).

The Intel Xeon E5-2660 v3 scores 1,802 in single-core performance and 12,996 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 4,839 for overall performance, 10,970 for productivity performance, 10,391 for creator performance, 13,727 for engineering performance and 8,655 for gaming performance. Its multi-core throughput works out to 1,300 per core, 650 per thread and 124 per watt. Its computed efficiency index is 472. Its performance index is 60, so its overall performance is 40% 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 E5-2660 v3 scores 51,982 in integer math, 26,104 in floating-point math, 216,794 in compression, 3,862 in cryptography, 780 in physics simulation, 13,696 in vector SIMD, 56 in the prime sieve and 29,176 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 12% below in integer math, 43% below in floating-point math, 5% below in compression, 66% below in cryptography, 28% below in physics simulation, 12% below in vector SIMD, 16% below in the prime sieve and 29% 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 E5-2660 v3 has 10 physical cores and runs 20 logical threads. It runs 2 threads per core. It runs at a base clock of 2.60 GHz and boosts up to 3.30 GHz.
