Intel® Xeon™ w7-3555

The Intel Xeon w7-3555 is a workstation processor with 28 cores and 56 threads, built on the Sapphire Rapids architecture. It launched in Jul 2024. Clocks run from 2.7 GHz base to 4.8 GHz boost. A 75-MB L3 cache backs the cores (4.8 MB per core). It addresses DDR5 memory up to 4 GB across 8 channels. The chip drops into the FCLGA4677 socket and exposes PCIe 5.0 (112 lanes). Rated TDP is 325 W. Notable platform capabilities: AMX, AVX-512, Extended Page Tables (EPT), Control-flow Enforcement (CET).

The Intel Xeon w7-3555 scores 3,549 in single-core performance and 67,754 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 15,507 for overall performance, 49,009 for productivity performance, 43,653 for creator performance, 90,621 for engineering performance and 27,586 for gaming performance. Its multi-core throughput works out to 2,420 per core, 1,210 per thread and 209 per watt. Its computed efficiency index is 860. Its performance index is 192, so its overall performance is 92% above 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 w7-3555 scores 244,642 in integer math, 190,917 in floating-point math, 966,970 in compression, 48,007 in cryptography, 5,802 in physics simulation, 77,619 in vector SIMD, 398 in the prime sieve and 96,112 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 315% above in integer math, 316% above in floating-point math, 324% above in compression, 318% above in cryptography, 432% above in physics simulation, 400% above in vector SIMD, 494% above in the prime sieve and 324% above 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 w7-3555 has 28 physical cores and runs 56 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 2.70 GHz and boosts up to 4.80 GHz.

The Intel Xeon w7-3555 is a workstation processor, belongs to the Intel Xeon W family, uses the Sapphire Rapids architecture and carries the codename Sapphire Rapids. It launched in Jul 2024.

The Intel Xeon w7-3555 has 2.19 MB of L1 cache, 56 MB of L2 cache and 75 MB of L3 cache. That adds up to about 133.2 MB of cache, or 4.76 MB per core. Each core has 2 MB of private L2 cache.

The Intel Xeon w7-3555 has a 3-level cache hierarchy: L1 at 2.2 MB, L2 at 56 MB and L3 at 75 MB. L3 is the largest level and makes up about 56% of the cache listed here.

The Intel Xeon w7-3555 supports DDR5 memory, addresses up to 4 GB of memory and uses 8 memory channels. It does not support DDR4 and LPDDR memory.

The Intel Xeon w7-3555 does not include integrated graphics, so a discrete graphics card is required for display output.

The Intel Xeon w7-3555 uses the FCLGA4677 socket, supports PCI Express 5.0 and provides up to 112 PCIe lanes.

The Intel Xeon w7-3555 has a rated TDP of 325 W.
