32-core Xeon Gold 6458Q for dual-socket servers

The Intel Xeon Gold 6458Q is a 32-core, 64-thread server processor built on 10 nm Sapphire Rapids architecture. It targets dual-socket platforms that need high core counts and large memory capacity for virtualisation, database and compute workloads. The LGA 4677 socket and 2S scalability define its deployment scope.

350 W TDP and turbo behaviour

Thermal design power is rated at 350 W, so substantial cooling capacity is required for sustained operation. Base frequency runs at 3.1 GHz with a maximum turbo frequency of 4.0 GHz across the 32 cores. Power draw and acoustic output will scale with the cooling solution chosen by the system integrator.

LGA 4677 mounting and platform connectivity

The processor drops into an LGA 4677 socket and provides 80 lanes of PCI Express 5.0 for high-speed storage, networking and accelerator cards. Eight-channel DDR5 4800 memory support enables up to 4 TB of system memory per socket. No cooling device is included in the package.

Questions about this item

How do I install the Intel Xeon Gold 6458Q into an LGA 4677 socket without bending pins?

Align the processor triangle marker with the socket corner, lower it straight down without forcing, then secure the carrier lever; the LGA 4677 socket has fragile pins on the motherboard side, so never press the chip after it seats.

What cooling maintenance will the 350 W Xeon Gold 6458Q require over time?

Replace thermal paste every two to three years and clean heatsink fins quarterly; the 350 W thermal design power demands a server-grade cooler rated for at least that TDP, and dust buildup reduces heat dissipation quickly.

At what point does the 32-core Xeon Gold 6458Q hit its power limit during sustained AVX-512 workloads?

The 350 W thermal design power is the first ceiling; under continuous AVX-512 the processor will throttle to stay within that envelope, so ensure your cooling solution can sustain 350 W heat removal indefinitely.
