Description

AMD EPYC 7543 (Milan) balances per-core speed with core count, delivering excellent performance for virtualization, databases, and HPC workloads. With 32 cores, 256MB L3, and PCIe Gen4, it supports dense NVMe, GPUs, and high-speed networking on SP3 platforms. Eight-channel DDR4-3200 ECC memory maximizes bandwidth for memory-heavy applications.

Features

- Zen 3 cores with large 256MB L3 for strong per-core and total throughput
- 128 lanes of PCIe 4.0 enable dense NVMe and accelerator footprints
- 8-channel DDR4-3200 ECC for high memory bandwidth
- Optimized for virtualization, databases, and mixed workloads
- 2-socket capable for scalable symmetric configurations
