Intel® Xeon™ E5-4640 v3

The Intel Xeon E5-4640 v3 is a server processor with 12 cores and 24 threads, built on the Haswell architecture. It launched in Apr 2015. Clocks run from 1.9 GHz base to 2.6 GHz boost. A 30-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 E5-4640 v3 scores 1,514 in single-core performance and 10,372 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 3,963 for overall performance, 8,861 for productivity performance, 8,430 for creator performance, 11,280 for engineering performance and 7,135 for gaming performance. Its multi-core throughput works out to 864 per core, 432 per thread and 99 per watt. Its computed efficiency index is 387. Its performance index is 49, so its overall performance is 51% 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.

Workload sub-scores (integer math, floating point, compression, encryption, physics, SIMD, prime sieve and sorting) are not recorded for the Intel Xeon E5-4640 v3.

The Intel Xeon E5-4640 v3 has 12 physical cores and runs 24 logical threads. It runs 2 threads per core. It runs at a base clock of 1.90 GHz and boosts up to 2.60 GHz.
