56-core Xeon for scale-out servers

The Intel Xeon Platinum 8480+ is a 56-core, 112-thread server processor built on a 10 nm Sapphire Rapids core. It targets dense compute clusters, large virtualisation hosts and memory-heavy analytics workloads that benefit from high core counts and eight-channel DDR5 bandwidth. Buyers needing single-thread speed or workstation-class features should look elsewhere.

LGA 4677 socket, no cooler included

Installation requires a server board with an LGA 4677 socket and a cooling solution rated for 350 W TDP; the processor ships without a heatsink or fan. Common issues include insufficient VRM phases on the motherboard, incorrect mounting pressure on the narrow integrated load mechanism, and BIOS revisions that do not yet support the Sapphire Rapids microcode.

4 TB DDR5 capacity with 80 PCIe 5.0 lanes

Eight memory channels accept up to 4 TB of DDR5 at 4800 MT/s in 1DPC or 4400 MT/s in 2DPC, giving ample headroom for in-memory databases. The 80 PCI Express 5.0 lanes support multiple accelerators or high-speed NICs, but platforms limited to fewer lanes or older PCIe revisions will constrain I/O throughput.

Questions about this item

How can I verify the Xeon Platinum 8480+ is running at its 2.0 GHz base frequency and 3.8 GHz max turbo after installation?

Enter the system BIOS or use a hardware monitoring utility to confirm the processor reports 56 cores, 112 threads and reaches 3.8 GHz under load.

What comes in the box with the PK8071305074801 and what must I purchase separately?

The processor only is supplied; a compatible LGA 4677 cooler, DDR5 memory modules and a server motherboard must be bought separately.

Which memory speed should I select for the Xeon Platinum 8480+ given the 4800 MT/s 1DPC and 4400 MT/s 2DPC limits?

Choose DDR5 4800 MT/s modules if populating one DIMM per channel, or DDR5 4400 MT/s if filling two DIMMs per channel across the eight channels.
