Intel® Xeon™ w9-3575X

The Intel Xeon w9-3575X is a workstation processor with 44 cores and 88 threads, built on the Sapphire Rapids architecture. It launched in Jul 2024. Clocks run from 2.2 GHz base to 4.8 GHz boost. A 97.5-MB L3 cache backs the cores (4.3 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 340 W. Notable platform capabilities: AMX, AVX-512, Extended Page Tables (EPT), Control-flow Enforcement (CET).

The Intel Xeon w9-3575X scores 3,662 in single-core performance and 83,098 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 17,444 for overall performance, 59,141 for productivity performance, 52,296 for creator performance, 116,337 for engineering performance and 31,761 for gaming performance. Its multi-core throughput works out to 1,889 per core, 944 per thread and 244 per watt. Its computed efficiency index is 946. Its performance index is 216, so its overall performance is 116% 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 w9-3575X scores 297,328 in integer math, 271,471 in floating-point math, 1,215,205 in compression, 62,177 in cryptography, 6,883 in physics simulation, 109,213 in vector SIMD, 681 in the prime sieve and 134,348 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 405% above in integer math, 491% above in floating-point math, 433% above in compression, 441% above in cryptography, 531% above in physics simulation, 604% above in vector SIMD, 916% above in the prime sieve and 493% 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 w9-3575X has 44 physical cores and runs 88 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 2.20 GHz and boosts up to 4.80 GHz.

The Intel Xeon w9-3575X 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 w9-3575X has 3.44 MB of L1 cache, 88 MB of L2 cache and 97.5 MB of L3 cache. That adds up to about 188.9 MB of cache, or 4.29 MB per core. Each core has 2 MB of private L2 cache.

The Intel Xeon w9-3575X has a 3-level cache hierarchy: L1 at 3.4 MB, L2 at 88 MB and L3 at 97.5 MB. L3 is the largest level and makes up about 52% of the cache listed here.

The Intel Xeon w9-3575X 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 w9-3575X does not include integrated graphics, so a discrete graphics card is required for display output.

The Intel Xeon w9-3575X uses the FCLGA4677 socket, supports PCI Express 5.0 and provides up to 112 PCIe lanes.

The Intel Xeon w9-3575X has a rated TDP of 340 W.
