Intel® Xeon™ E5-2676 v3

The Intel Xeon E5-2676 v3 is a server processor with 12 cores and 24 threads, built on the Haswell architecture. It launched in 2015. Clocks run from 2.4 GHz base to 3.0 GHz boost. A 30-MB L3 cache backs the cores (2.8 MB per core). It supports DDR3, DDR4 memory. It uses the FCLGA2011-3 socket. Rated TDP is 120 W.

The Intel Xeon E5-2676 v3 scores 1,602 in single-core performance and 12,952 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 4,555 for overall performance, 10,662 for productivity performance, 10,007 for creator performance, 14,085 for engineering performance and 8,044 for gaming performance. Its multi-core throughput works out to 1,079 per core, 540 per thread and 108 per watt. Its computed efficiency index is 416. Its performance index is 56, so its overall performance is 44% 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 E5-2676 v3 scores 57,378 in integer math, 28,781 in floating-point math, 237,981 in compression, 3,652 in cryptography, 635 in physics simulation, 15,053 in vector SIMD, 51 in the prime sieve and 30,624 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 3% below in integer math, 37% below in floating-point math, 4% above in compression, 68% below in cryptography, 42% below in physics simulation, 3% below in vector SIMD, 24% below in the prime sieve and 35% 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 E5-2676 v3 has 12 physical cores and runs 24 logical threads. It runs 2 threads per core. It runs at a base clock of 2.40 GHz and boosts up to 3.00 GHz.
