56-core EPYC 7663P server processor

The AMD EPYC 7663P is a 56-core, 112-thread server CPU built for Socket SP3 platforms. It operates at a 2.0 GHz base frequency and can reach a 3.5 GHz max turbo frequency. The processor includes 28 MB of L2 cache and 256 MB of L3 cache to handle demanding multi-threaded workloads.

DDR4-3200 eight-channel memory and PCIe 4.0 limits

The integrated memory controller supports DDR4 at 3200 MT/s across eight channels for high bandwidth. The processor provides 128 lanes of PCI Express 4.0 connectivity for add-in cards and storage. System memory speed and PCIe lane allocation depend on the specific motherboard implementation and BIOS configuration.

Socket SP3 platform and 240 W thermal design power

Verify that your motherboard uses the Socket SP3 interface and delivers sufficient power for the 240 W TDP. A compatible cooling solution is required as none is included in the package. Ensure the system firmware supports the EPYC 7003 series before installation.

Questions about this item

Should I pick the 56-core EPYC 7663P or a lower-core model from the 7003 series?

Choose the 56-core 7663P when your workloads need 112 threads and 256 MB L3 cache; a lower-core model reduces thread count and cache proportionally.

What does the 3.5 GHz max turbo frequency deliver in a live server?

The 3.5 GHz max turbo lets individual cores burst above the 2.0 GHz base for short periods, improving single-thread latency while the 240 W TDP governs sustained all-core speed.

How does the PCI Express 4.0 interface with 128 lanes limit expansion?

PCIe 4.0 provides 128 lanes total, so each lane runs at the 4.0 rate; you can populate up to 128 lanes of devices such as GPUs, storage controllers or NICs without exceeding the CPU link budget.
