Intel® Xeon™ E5-1603

The Intel Xeon E5-1603 is a server processor with 4 cores and 4 threads, built on the Sandy Bridge architecture. It launched in Mar 2012. A 10-MB L3 cache backs the cores (2.8 MB per core). It supports DDR3 memory. It uses the FCLGA2011 socket. Rated TDP is 130 W.

The Intel Xeon E5-1603 scores 1,334 in single-core performance and 3,472 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 2,152 for overall performance, 4,124 for productivity performance, 4,311 for creator performance, 3,342 for engineering performance and 4,870 for gaming performance. Its multi-core throughput works out to 868 per core, 868 per thread and 27 per watt. Its computed efficiency index is 189. Its performance index is 27, so its overall performance is 73% 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 E5-1603 scores 11,826 in integer math, 6,055 in floating-point math, 54,723 in compression, 863 in cryptography, 359 in physics simulation, 2,757 in vector SIMD, 28 in the prime sieve and 7,364 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 80% below in integer math, 87% below in floating-point math, 76% below in compression, 92% below in cryptography, 67% below in physics simulation, 82% below in vector SIMD, 58% below in the prime sieve and 67% 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 E5-1603 has 4 physical cores and runs 4 logical threads. It does not use a hybrid performance and efficiency core layout. It does not support simultaneous multithreading, so its thread count equals its core count. It runs at a base clock of 2.80 GHz.

The Intel Xeon E5-1603 is a server processor, belongs to the Intel Xeon E5 family and uses the Sandy Bridge architecture. It launched in Mar 2012.

The Intel Xeon E5-1603 has 256 KB of L1 cache, 1 MB of L2 cache and 10 MB of L3 cache. That adds up to about 11.3 MB of cache, or 2.81 MB per core. Each core has 256 KB of private L2 cache.

The Intel Xeon E5-1603 has a 3-level cache hierarchy: L1 at 256 KB, L2 at 1 MB and L3 at 10 MB. L3 is the largest level and makes up about 89% of the cache listed here.

The Intel Xeon E5-1603 supports DDR3 memory and runs memory at up to 1,066 MT/s. It does not support DDR5, DDR4 and LPDDR memory.

The Intel Xeon E5-1603 uses the FCLGA2011 socket.

The Intel Xeon E5-1603 has a rated TDP of 130 W.
