56-Core EPYC 7663 Server Processor

The AMD EPYC 7663 is a 56-core server processor built on the Milan architecture. It runs at a 2.0 GHz base frequency with a 3.5 GHz maximum turbo frequency. The chip provides 112 threads and 256 MB of L3 cache in a Socket SP3 package.

Suited For Multi-Threaded Workloads

This processor suits virtualisation hosts, database servers and compute clusters that need high core counts and 128 PCIe 4.0 lanes. It is not for buyers who need an integrated cooling solution, as the processor is sold without a cooling device. It is also not for systems limited to lower TDP envelopes.

240 W Thermal Design Power

The processor has a thermal design power of 240 W. This figure determines the cooling capacity and power delivery the motherboard and chassis must provide. Ensure the platform can sustain 240 W continuous heat dissipation before selecting this part.

Questions about this item

What motherboard socket and memory type does the EPYC 7663 require?

The processor fits a Socket SP3 motherboard and uses DDR4 memory controlled through eight channels at 3200 MT/s.

Will my existing PCIe 3.0 add-in cards work with the 128 PCIe 4.0 lanes?

Yes, PCIe 4.0 is backward compatible so PCIe 3.0 cards will operate at their rated 3.0 speeds across the available lanes.

How can I confirm the 56 cores and 112 threads are active after installation?

Check the operating system task manager or run a CPU identification utility; it should report 56 cores, 112 threads and a 2.0 GHz base frequency.
