Intel Xeon Platinum 8558 48 Cores 96 Threads 4GHz E (LGA 4677) PK8072205512300 Server CPU

High-Density Data Center Server CPU architecture with the Intel Xeon Platinum 8558 (SKU PK8072205512300)

The Intel Xeon Platinum 8558 is a 5th Gen Intel Xeon Scalable Emerald Rapids-SP tray processor for LGA4677 platforms, designed for 1S and 2S enterprise servers where predictable throughput, memory bandwidth, and modern I/O define node efficiency. With 48 cores and 96 threads, the Intel Xeon Platinum 8558 targets consolidation-heavy virtualisation clusters and private cloud compute nodes that require consistent performance under mixed VM and container scheduling.

The Intel Xeon Platinum 8558 couples DDR5 up to 5200 MT/s with ECC and up to 4TB memory capacity to sustain in-memory databases, large JVM footprints, and analytics pipelines with reduced paging pressure. PCIe 5.0 connectivity with up to 80 lanes enables high-bandwidth attachment for NVMe storage fabrics and accelerator-class I/O for CPU-centric AI inference, while maintaining balanced expansion for high-speed networking. In 2S designs, 4 UPI links provide the inter-socket bandwidth needed for NUMA-aware database and HPC deployments. Note that the Intel Xeon Platinum 8558 has no integrated GPU and is supplied without a cooler, supporting data center thermal and airflow planning.
