28-Core EPYC 7453 Server Processor

The AMD EPYC 7453 is a 28-core server processor built for the Socket SP3 platform. It operates at a 2.75 GHz base frequency and can reach a 3.45 GHz max turbo frequency. The chip provides 56 threads and 64 MB of L3 cache within a 225 W thermal design power envelope.

Suited for Dense DDR4 Platforms

This processor fits data centres that have qualified DDR4 3200 memory and PCIe 4.0 infrastructure across eight memory channels and 128 lanes. It is not for builds that require a different socket, a lower power target, or memory technology beyond the supported DDR4 standard.

64 MB L3 Cache Capacity

The 64 MB L3 cache delivers a high hit rate for complex, multi-threaded workloads and virtualisation tasks. This cache size determines whether the processor can keep large working sets close to the 28 cores without frequent main memory access.

Questions about this item

What motherboard socket and CPU cooler clearance does the EPYC 7453 require?

The processor fits Socket SP3 and has a 225 W thermal design power; a compatible server cooler rated for at least 225 W must be sourced separately because no cooling device is included.

How is the EPYC 7453 installed, and what step is often missed?

Place the CPU into the SP3 LGA socket, close the retention frame and torque the captive screws in the prescribed sequence; the step often missed is applying fresh thermal paste before mounting the cooler.

When will the EPYC 7453 need thermal-paste replacement or cooler servicing?

Plan to refresh thermal paste every two to three years or whenever the cooler is removed, because the 225 W TDP and continuous server loads degrade paste faster than desktop workloads.
