AMD EPYC 7443P
The AMD EPYC 7443P is a 24-core, 48-thread single-socket dedicated server processor based on the 7nm Zen 3 architecture for Socket SP3. Designed to deliver high single-thread velocity and enterprise I/O for 1-socket (1P) server platforms, it operates with a 2.85 GHz base clock, boost up to 4.00 GHz, 128MB of L3 cache, and a 200W TDP. It provides the full 8 channels of DDR4-3200 memory and 128 lanes of PCIe 4.0 expansion typically reserved for high-end dual-socket servers, allowing customers to build economical single-socket storage appliances, virtualization nodes, and branch office servers without paying dual-socket hardware or licensing premiums. Used buyers should check PSB locking.
