Intel Xeon Platinum 8444H server processor

The Intel Xeon Platinum 8444H is a 16-core server processor built for data-centre workloads. It delivers 32 threads at a 2.9 GHz base frequency with a 4.0 GHz maximum turbo. The 45 MB L3 cache and eight-channel DDR5 memory controller support up to 4 TB of system memory. This CPU targets virtualisation, database and high-performance computing deployments.

LGA 4677 socket compatibility

This processor fits only the LGA 4677 socket used by Intel Xeon Scalable platforms. The 10 nm Sapphire Rapids die provides 80 lanes of PCI Express 5.0 for high-speed I/O. A motherboard with the matching socket and appropriate chipset is required for installation. Builders using any other socket type cannot use this part.

270 W thermal design power and memory headroom

The 270 W TDP demands robust server-grade cooling; no cooler is included in the package. Eight memory channels running DDR5 at up to 4800 MT/s per DIMM provide ample bandwidth for memory-intensive tasks. Workloads exceeding 4 TB total memory or requiring more than 16 cores will need a higher-tier processor.

Questions about this item

What does the 2.9 GHz base frequency deliver in a real server workload?

The 16 cores run at 2.9 GHz continuously within the 270 W envelope, giving predictable throughput for multi-threaded tasks such as virtualization or database serving.

How does the PCI Express 5.0 interface limit expansion cards?

The processor provides 80 lanes of PCI Express 5.0, so each device operates at 5.0 speeds up to the lane budget; total bandwidth scales with the number of lanes assigned.

What physical space and power does the LGA 4677 socket require?

The chip fits the LGA 4677 socket and draws 270 W, so the board must deliver that power and the cooler must dissipate it; no cooling device is included.
