Intel® Xeon™ E5-4603

The Intel Xeon E5-4603 is a server processor with 4 cores and 8 threads, built on the Sandy Bridge architecture. It launched in Apr 2012. A 10-MB L3 cache backs the cores (2.9 MB per core). It addresses DDR3 memory up to 384 GB across 4 channels. The chip drops into the FCLGA2011 socket and exposes PCIe 3.0 (40 lanes). Rated TDP is 95 W. Notable platform capabilities: Extended Page Tables (EPT).

The Intel Xeon E5-4603 scores 953 in single-core performance and 3,391 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 1,798 for overall performance, 3,538 for productivity performance, 3,580 for creator performance, 3,264 for engineering performance and 3,707 for gaming performance. Its multi-core throughput works out to 848 per core, 424 per thread and 36 per watt. Its computed efficiency index is 184. Its performance index is 22, so its overall performance is 78% 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 E5-4603.

The Intel Xeon E5-4603 has 4 physical cores and runs 8 logical threads. It runs 2 threads per core. It runs at a base clock of 2.00 GHz.
