Intel® Xeon™ Platinum 8454H

The Intel Xeon Platinum 8454H is a server processor with 32 cores and 64 threads, built on the Sapphire Rapids architecture. It launched in Jan 2023. Clocks run from 2.1 GHz base to 3.4 GHz boost. A 82.5-MB L3 cache backs the cores (2.6 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 (80 lanes). Rated TDP is 270 W. Notable platform capabilities: AMX (Advanced Matrix Extensions), AMX, AVX-512, Extended Page Tables (EPT).

The Intel Xeon Platinum 8454H scores 2,831 in single-core performance and 62,347 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 13,285 for overall performance, 44,489 for productivity performance, 39,387 for creator performance, 87,286 for engineering performance and 24,080 for gaming performance. Its multi-core throughput works out to 1,948 per core, 974 per thread and 231 per watt. Its computed efficiency index is 809. Its performance index is 165, so its overall performance is 65% 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 Platinum 8454H scores 231,421 in integer math, 164,874 in floating-point math, 850,479 in compression, 51,263 in cryptography, 7,445 in physics simulation, 66,681 in vector SIMD, 366 in the prime sieve and 113,491 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 293% above in integer math, 259% above in floating-point math, 273% above in compression, 346% above in cryptography, 583% above in physics simulation, 330% above in vector SIMD, 446% above in the prime sieve and 401% 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 Platinum 8454H has 32 physical cores and runs 64 logical threads. It runs 2 threads per core. It runs at a base clock of 2.10 GHz and boosts up to 3.40 GHz.

The Intel Xeon Platinum 8454H is a server processor, belongs to the Intel Xeon Platinum family, uses the Sapphire Rapids architecture and carries the codename Sapphire Rapids. It launched in Jan 2023.

The Intel Xeon Platinum 8454H has 82.5 MB of L3 cache. That adds up to about 82.5 MB of cache, or 2.58 MB per core. Feex has no recorded L1 cache size for this processor.

The Intel Xeon Platinum 8454H 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 Platinum 8454H does not include integrated graphics, so a discrete graphics card is required for display output.

The Intel Xeon Platinum 8454H uses the FCLGA4677 socket, supports PCI Express 5.0 and provides up to 80 PCIe lanes.

The Intel Xeon Platinum 8454H has a rated TDP of 270 W.
