32-core Xeon 6 for single-socket servers

The Intel Xeon 6731P is a 32-core, 64-thread server processor built on a 3 nm process and designed for the FCLGA 4710 socket. It targets single-socket platforms that need high core density and large memory capacity without multi-socket complexity. The chip supports DDR5 6400 memory up to 4 TB and provides 136 lanes of PCI Express 5.0 for fast storage and accelerator connectivity. Buyers who need multi-socket scaling or a bundled cooler should look elsewhere.

Sustained all-core turbo at 3.9 GHz

Under continuous multi-threaded load the processor maintains an all-core turbo frequency of 3.9 GHz across its 32 cores. This steady clock speed is well above the 2.5 GHz base and close to the 4.1 GHz single-core maximum, so throughput does not collapse when every thread is active. Workloads such as database serving, virtualization hosting and scientific simulation benefit from the consistent frequency. The 144 MB L3 cache helps keep data close to the cores during long runs.

245 W TDP requires adequate cooling

The thermal design power is rated at 245 W, reflecting the heat output when all cores run at the all-core turbo frequency. No cooling device is included, so a server-grade heatsink or liquid loop rated for at least this TDP must be sourced separately. Power draw will track workload intensity, but sustained heavy compute will approach the rated figure. Acoustic noise depends entirely on the chosen cooling solution and chassis airflow design.

Questions about this item

How much heat does the 245 W TDP generate when all 32 cores run at 3.9 GHz continuously?

The processor is rated at 245 W thermal design power. At the 3.9 GHz all-core turbo frequency the chip will sustain that power level, so plan cooling capacity for at least 245 W of heat removal.

Which memory modules and motherboard socket are required for the FCLGA 4710 package?

You need a motherboard with an FCLGA 4710 socket and DDR5 modules rated for 6400 MT/s. The integrated memory controller supports up to 4 TB of DDR5 across the available channels.

Can the 136 PCIe 5.0 lanes connect to existing PCIe 4.0 add-in cards without a bottleneck?

The CPU provides 136 lanes of PCI Express 5.0. PCIe 4.0 cards will operate at their native 4.0 speeds on these lanes; the interface is backward compatible, so older cards work but do not gain 5.0 bandwidth.
