Intel® Xeon™ Platinum 8470

The Intel Xeon Platinum 8470 is a server processor with 52 cores and 104 threads, built on the Sapphire Rapids architecture. It launched in Jan 2023. Clocks run from 2.0 GHz base to 3.8 GHz boost. A 105-MB L3 cache backs the cores (2.0 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 350 W. Notable platform capabilities: AMX (Advanced Matrix Extensions), AMX, AVX-512, Extended Page Tables (EPT).

The Intel Xeon Platinum 8470 scores 3,153 in single-core performance and 89,850 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 16,831 for overall performance, 62,817 for productivity performance, 55,093 for creator performance, 125,790 for engineering performance and 31,922 for gaming performance. Its multi-core throughput works out to 1,728 per core, 864 per thread and 257 per watt. Its computed efficiency index is 900. Its performance index is 209, so its overall performance is 109% 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 8470 scores 418,386 in integer math, 296,902 in floating-point math, 1,464,729 in compression, 91,348 in cryptography, 7,673 in physics simulation, 105,059 in vector SIMD, 529 in the prime sieve and 182,474 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 610% above in integer math, 547% above in floating-point math, 542% above in compression, 695% above in cryptography, 604% above in physics simulation, 577% above in vector SIMD, 690% above in the prime sieve and 706% 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 8470 has 52 physical cores and runs 104 logical threads. It runs 2 threads per core. It runs at a base clock of 2.00 GHz and boosts up to 3.80 GHz.

The Intel Xeon Platinum 8470 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 8470 has 105 MB of L3 cache. That adds up to about 105.0 MB of cache, or 2.02 MB per core. Feex has no recorded L1 cache size for this processor.

The Intel Xeon Platinum 8470 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 8470 does not include integrated graphics, so a discrete graphics card is required for display output.

The Intel Xeon Platinum 8470 uses the FCLGA4677 socket, supports PCI Express 5.0 and provides up to 80 PCIe lanes.

The Intel Xeon Platinum 8470 has a rated TDP of 350 W.
