Server processor for dense compute

The AMD EPYC 7402 is a 24-core Socket SP3 CPU built for dual-processor servers and high-thread workloads such as virtualisation, database hosting and rendering. It runs at 2.8 GHz base with a 3.35 GHz maximum turbo and provides 128 MB of L3 cache alongside 48 threads. The 7 nm process helps keep the thermal design power at 180 W.

Suited for multi-socket scaling not single-thread

This part targets administrators who need 128 PCIe 4.0 lanes and eight DDR4 3200 channels across two sockets for memory-heavy clusters or storage nodes. Builders looking for higher per-core frequency or a lower power envelope for single-socket workstations should evaluate other options.

Socket SP3 with 128 PCIe 4.0 lanes

The processor fits Socket SP3 platforms and exposes up to 128 lanes of PCI Express 4.0 for add-in cards and storage controllers. A compatible cooler rated for 180 W TDP must be sourced separately as no cooling device is included.

Questions about this item

How do I install the EPYC 7402 into a Socket SP3 board, and which step is most often done wrong?

Align the gold triangle on the processor with the socket triangle, lower the retention frame, then torque the captive screws in a cross pattern to the board vendor's specified value; skipping the cross-pattern torque sequence is the step most often done wrong.

What maintenance or replacement will the EPYC 7402 need later?

The processor itself has no serviceable parts; plan to replace the thermal interface material whenever the cooler is removed, and verify that the platform firmware supports the 7402 before deployment.

What limit appears first when the EPYC 7402 runs sustained workloads at its 180W TDP?

The 180W thermal design power is the first limit; the socket and cooler must dissipate that heat continuously or the processor will throttle to stay within its thermal envelope.
