96-core Xeon for dense compute

The Intel Xeon 6731E packs 96 cores and 96 threads into a single FCLGA 4710 socket. Base frequency sits at 2.2 GHz with a maximum turbo of 3.1 GHz. The chip targets workloads that scale across many parallel threads such as cloud infrastructure, virtualisation hosts and high-throughput data analytics.

250 W TDP and thermal profile

Rated at 250 W, the processor draws significant power under full load and requires robust server-grade cooling. Eight-channel DDR5 6400 memory support feeds the cores with high bandwidth while the 3 nm manufacturing process helps contain leakage. No UPI links are present, so the part is limited to single-socket deployments.

PCIe 5.0 and memory capacity

The platform exposes PCI Express 5.0 lanes for modern accelerators and storage controllers. Maximum addressable memory reaches 4 TB across eight channels, enabling large in-memory databases. Virtualisation technology is supported in hardware, but the lack of multi-socket scaling means buyers needing larger NUMA domains must look elsewhere.

Questions about this item

How is the FCLGA 4710 processor installed and what step is often missed?

Align the notches on the 96-core CPU with the socket keys, lower it straight down without pressure, then close the load-plate lever until it clicks; the step most often missed is torquing the heatsink mounting screws in the prescribed diagonal sequence so the 250 W TDP makes full contact.

What maintenance or replacement will the Xeon 6731E need later?

The processor itself has no user-serviceable parts; plan to replace thermal paste every two to three years and verify the cooler’s fan curve handles sustained 250 W loads, while DDR5 6400 memory and PCIe 5.0 devices can be upgraded independently.

What limit appears first when the 96 cores run at max turbo continuously?

The 250 W thermal envelope is reached before the 3.1 GHz max turbo can be held across all 96 threads, so the CPU throttles to the 2.2 GHz base frequency once the cooler saturates.
