Intel® Xeon™ w7-3465X

The Intel Xeon w7-3465X is a workstation processor with 28 cores and 56 threads, built on the Sapphire Rapids architecture. It launched in Jan 2023. Clocks run from 2.5 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 300 W. Notable platform capabilities: AMX, AVX-512, Extended Page Tables (EPT), Control-flow Enforcement (CET).

The Intel Xeon w7-3465X scores 3,183 in single-core performance and 61,559 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 13,998 for overall performance, 44,470 for productivity performance, 39,587 for creator performance, 82,335 for engineering performance and 24,939 for gaming performance. Its multi-core throughput works out to 2,199 per core, 1,099 per thread and 205 per watt. Its computed efficiency index is 808. Its performance index is 173, so its overall performance is 73% 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 w7-3465X scores 232,584 in integer math, 180,529 in floating-point math, 886,759 in compression, 45,928 in cryptography, 4,625 in physics simulation, 77,860 in vector SIMD, 359 in the prime sieve and 90,491 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 295% above in integer math, 293% above in floating-point math, 289% above in compression, 300% above in cryptography, 324% above in physics simulation, 402% above in vector SIMD, 436% above in the prime sieve and 299% 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 w7-3465X 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 2.50 GHz and boosts up to 4.80 GHz.

The Intel Xeon w7-3465X 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 Jan 2023.

The Intel Xeon w7-3465X 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 w7-3465X 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 w7-3465X 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 w7-3465X does not include integrated graphics, so a discrete graphics card is required for display output.

The Intel Xeon w7-3465X uses the FCLGA4677 socket, supports PCI Express 5.0 and provides up to 112 PCIe lanes.

The Intel Xeon w7-3465X has a rated TDP of 300 W.
