Intel® Xeon™ Platinum 8558

The Intel Xeon Platinum 8558 is a server processor with 48 cores and 96 threads, built on the Emerald Rapids architecture. It launched in Oct 2023. Clocks run from 2.1 GHz base to 4.0 GHz boost. A 260-MB L3 cache backs the cores (5.4 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 330 W. Notable platform capabilities: AMX (Advanced Matrix Extensions), AMX, AVX-512, Extended Page Tables (EPT).

The Intel Xeon Platinum 8558 has 48 physical cores and runs 96 logical threads. It runs 2 threads per core. It runs at a base clock of 2.10 GHz and boosts up to 4.00 GHz.

The Intel Xeon Platinum 8558 is a server processor, belongs to the Intel Xeon Platinum family, uses the Emerald Rapids architecture and carries the codename Emerald Rapids. It launched in Oct 2023.

The Intel Xeon Platinum 8558 has 260 MB of L3 cache. That adds up to about 260.0 MB of cache, or 5.42 MB per core. Feex has no recorded L1 cache size for this processor.

The Intel Xeon Platinum 8558 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 8558 does not include integrated graphics, so a discrete graphics card is required for display output.

The Intel Xeon Platinum 8558 uses the FCLGA4677 socket, supports PCI Express 5.0 and provides up to 80 PCIe lanes.

The Intel Xeon Platinum 8558 has a rated TDP of 330 W.
