Intel® Xeon™ W3580

The Intel Xeon W3580 is a server processor with 4 cores and 8 threads, built on the Nehalem architecture. It launched in Aug 2009. Clocks run from 3.33 GHz base to 3.6 GHz boost. A 8-MB L3 cache backs the cores (2.3 MB per core). It supports DDR3 memory. It uses the FCLGA1366 socket. Rated TDP is 130 W. Notable platform capabilities: AVX-512, Extended Page Tables (EPT).

The Intel Xeon W3580 scores 1,556 in single-core performance and 3,638 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 2,379 for overall performance, 4,543 for productivity performance, 4,802 for creator performance, 3,502 for engineering performance and 5,578 for gaming performance. Its multi-core throughput works out to 910 per core, 455 per thread and 28 per watt. Its computed efficiency index is 209. Its performance index is 29, so its overall performance is 71% 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 W3580 scores 19,505 in integer math, 8,365 in floating-point math, 80,927 in compression, 665 in cryptography, 439 in physics simulation, 2,234 in vector SIMD, 25 in the prime sieve and 11,247 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 67% below in integer math, 82% below in floating-point math, 65% below in compression, 94% below in cryptography, 60% below in physics simulation, 86% below in vector SIMD, 63% below in the prime sieve and 50% 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 W3580 has 4 physical cores and runs 8 logical threads. It does not use a hybrid performance and efficiency core layout. It runs 2 threads per core. It runs at a base clock of 3.33 GHz and boosts up to 3.60 GHz.

The Intel Xeon W3580 is a server processor, belongs to the Intel Xeon W family and uses the Nehalem architecture. It launched in Aug 2009.

The Intel Xeon W3580 has 256 KB of L1 cache, 1 MB of L2 cache and 8 MB of L3 cache. That adds up to about 9.3 MB of cache, or 2.31 MB per core. Each core has 256 KB of private L2 cache.

The Intel Xeon W3580 has a 3-level cache hierarchy: L1 at 256 KB, L2 at 1 MB and L3 at 8 MB. L3 is the largest level and makes up about 86% of the cache listed here.

The Intel Xeon W3580 supports DDR3 memory and runs memory at up to 1,333 MT/s. It does not support DDR5, DDR4 and LPDDR memory.
