Intel Xeon Max 9460 40-core server processor

The Intel Xeon Max 9460 is a 40-core server processor with 80 threads and a base frequency of 2.2 GHz. It targets data-centre workloads that scale across many cores, such as large-scale analytics, scientific modelling and dense virtualisation. The LGA 4677 socket and 2-socket scalability fit standard dual-socket server platforms.

Sustained 350 W thermal design power

A thermal design power of 350 W means the chip is built to run at high utilisation for extended periods when paired with adequate server cooling. The 10 nm Sapphire Rapids architecture and 97.5 MB L3 cache help maintain throughput on memory-intensive tasks without throttling. Turbo frequency reaches 3.5 GHz for burst phases, but sustained loads rely on the base clock and cooling capacity.

LGA 4677 socket, eight-channel DDR5, PCIe 5.0

The processor installs into an LGA 4677 socket and requires a compatible server board with robust power delivery. Eight memory channels support up to 4 TB of DDR5 at 4800 MT/s single-DIMM or 4400 MT/s dual-DIMM per channel. Eighty PCIe 5.0 lanes provide high-bandwidth connectivity for accelerators, storage and networking. No cooling device is included.

Questions about this item

How much heat does the 350 W TDP generate when the Xeon Max 9460 runs at full load all day?

The processor has a 350 W thermal design power, so sustained full-load operation will dissipate that much heat and requires a server-grade cooler rated for at least 350 W.

What memory and motherboard must I already have to install this LGA 4677 CPU?

You need a motherboard with an LGA 4677 socket and DDR5 modules — up to 4800 MT/s with one DIMM per channel or 4400 MT/s with two DIMMs per channel across eight channels.

Will the PCIe 5.0 lanes on this 40-core Xeon work with my existing PCIe 4.0 add-in cards?

Yes, the 80 lanes of PCI Express 5.0 are backward compatible, so PCIe 4.0 cards will operate at their rated 4.0 speeds.
