Intel® Xeon™ Platinum 8450H

The Intel Xeon Platinum 8450H is a server processor with 28 cores and 56 threads, built on the Sapphire Rapids architecture. It launched in Jan 2023. Clocks run from 2.0 GHz base to 3.5 GHz boost. A 75-MB L3 cache backs the cores (2.7 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 250 W. Notable platform capabilities: AMX (Advanced Matrix Extensions), AMX, AVX-512, Extended Page Tables (EPT).

The Intel Xeon Platinum 8450H has 28 physical cores and runs 56 logical threads. It runs 2 threads per core. It runs at a base clock of 2.00 GHz and boosts up to 3.50 GHz.

The Intel Xeon Platinum 8450H 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 8450H has 75 MB of L3 cache. That adds up to about 75.0 MB of cache, or 2.68 MB per core. Feex has no recorded L1 cache size for this processor.

The Intel Xeon Platinum 8450H 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 8450H does not include integrated graphics, so a discrete graphics card is required for display output.

The Intel Xeon Platinum 8450H uses the FCLGA4677 socket, supports PCI Express 5.0 and provides up to 80 PCIe lanes.

The Intel Xeon Platinum 8450H has a rated TDP of 250 W.
