Intel® Xeon™ X5675

The Intel Xeon X5675 is a server processor with 6 cores and 12 threads, built on the Westmere architecture. It launched in 2011. Clocks run from 3.1 GHz base to 3.5 GHz boost. A 12-MB L3 cache backs the cores (2.3 MB per core). It supports DDR3 memory. It uses the FCLGA1366 socket. Rated TDP is 95 W.

The Intel Xeon X5675 scores 1,484 in single-core performance and 6,438 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 3,091 for overall performance, 6,262 for productivity performance, 6,212 for creator performance, 6,398 for engineering performance and 6,062 for gaming performance. Its multi-core throughput works out to 1,073 per core, 537 per thread and 68 per watt. Its computed efficiency index is 317. Its performance index is 38, so its overall performance is 62% 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 X5675 scores 27,113 in integer math, 11,570 in floating-point math, 111,198 in compression, 2,357 in cryptography, 448 in physics simulation, 3,173 in vector SIMD, 30 in the prime sieve and 14,408 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 54% below in integer math, 75% below in floating-point math, 51% below in compression, 79% below in cryptography, 59% below in physics simulation, 80% below in vector SIMD, 55% below in the prime sieve and 36% 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 X5675 has 6 physical cores and runs 12 logical threads. It runs 2 threads per core. It runs at a base clock of 3.10 GHz and boosts up to 3.50 GHz.

The Intel Xeon X5675 is a server processor, belongs to the Intel Xeon family and uses the Westmere architecture. It launched in 2011.

The Intel Xeon X5675 has 384 KB of L1 cache, 1.50 MB of L2 cache and 12 MB of L3 cache. That adds up to about 13.9 MB of cache, or 2.31 MB per core. Each core has 256 KB of private L2 cache.

The Intel Xeon X5675 has a 3-level cache hierarchy: L1 at 384 KB, L2 at 1.5 MB and L3 at 12 MB. L3 is the largest level and makes up about 86% of the cache listed here.
