Intel PK8071305121300 Xeon Gold 6448H 32-core server processor

Socket LGA 4677 server processor

The Intel Xeon Gold 6448H is a 32-core, 64-thread CPU built on 10 nm Sapphire Rapids architecture. It runs at a 2.4 GHz base frequency with a 4.1 GHz maximum turbo. Designed for multi-socket servers, it supports up to 4 TB of DDR5 4800 memory across eight channels and provides 80 PCIe 5.0 lanes. The 250 W thermal design power requires robust cooling in a compatible chassis.

Verify motherboard and memory compatibility

Confirm the board uses the LGA 4677 socket and supports the S4S scalability topology. Ensure the platform firmware is updated for 4th Generation Xeon Scalable processors. Memory must be DDR5 4800; earlier DDR generations will not fit or function. The 80 PCIe 5.0 lanes need matching backplane or riser support for full utilisation.

Processor-only packaging demands adequate cooling

The unit ships without a heatsink or fan, so a 250 W-rated server cooler must be sourced separately. Eight memory channels mean eight DIMM slots per socket; populate all for maximum bandwidth. The 60 MB L3 cache and Intel AMX, AVX-512 instruction sets accelerate AI and HPC workloads. Multi-socket trays need sufficient airflow to sustain turbo frequencies under load.
