Intel® Xeon™ w7-3455

The Intel Xeon w7-3455 is a workstation processor with 24 cores and 48 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 67.5-MB L3 cache backs the cores (4.9 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 270 W. Notable platform capabilities: AMX, AVX-512, Extended Page Tables (EPT), Control-flow Enforcement (CET).

The Intel Xeon w7-3455 scores 3,058 in single-core performance and 53,588 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 12,801 for overall performance, 39,113 for productivity performance, 34,978 for creator performance, 68,325 for engineering performance and 22,571 for gaming performance. Its multi-core throughput works out to 2,233 per core, 1,116 per thread and 199 per watt. Its computed efficiency index is 779. Its performance index is 159, so its overall performance is 59% 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 w7-3455 scores 201,576 in integer math, 156,993 in floating-point math, 781,639 in compression, 39,380 in cryptography, 3,260 in physics simulation, 60,641 in vector SIMD, 292 in the prime sieve and 79,669 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 242% above in integer math, 242% above in floating-point math, 243% above in compression, 243% above in cryptography, 199% above in physics simulation, 291% above in vector SIMD, 336% above in the prime sieve and 252% 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 w7-3455 has 24 physical cores and runs 48 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 w7-3455 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 w7-3455 has 1.88 MB of L1 cache, 48 MB of L2 cache and 67.5 MB of L3 cache. That adds up to about 117.4 MB of cache, or 4.89 MB per core. Each core has 2 MB of private L2 cache.

The Intel Xeon w7-3455 has a 3-level cache hierarchy: L1 at 1.9 MB, L2 at 48 MB and L3 at 67.5 MB. L3 is the largest level and makes up about 58% of the cache listed here.

The Intel Xeon w7-3455 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 w7-3455 does not include integrated graphics, so a discrete graphics card is required for display output.

The Intel Xeon w7-3455 uses the FCLGA4677 socket, supports PCI Express 5.0 and provides up to 112 PCIe lanes.

The Intel Xeon w7-3455 has a rated TDP of 270 W.
