Server processor for single-socket platforms

The Intel Xeon Gold 5412U is a 24-core, 48-thread server CPU built on 10 nm Sapphire Rapids silicon. It targets single-socket systems that need high thread counts and large memory capacity without multi-socket complexity.

185 W base power with DDR5 4400 support

The processor carries a 185 W thermal design power and integrates an eight-channel DDR5 4400 memory controller. In normal operation the chip runs at 2.1 GHz base frequency and can reach 3.9 GHz maximum turbo frequency across its cores.

1S-only scalability limits deployment options

This model supports single-socket configurations only, so it cannot be used in dual-socket or larger scale-up servers. The 80 PCI Express 5.0 lanes and 45 MB L3 cache remain available within that single-socket constraint.

Fragen zu diesem Artikel

How do I install this LGA 4677 socket processor and which step is most often done incorrectly?

Align the notches on the CPU with the socket keys, lower it straight down without force, then close the retention lever until it clicks; the step most often missed is verifying the lever is fully latched before applying thermal paste.

What maintenance or replacement will this 185 W Xeon Gold 5412U need over its service life?

Plan to replace the thermal interface material every two to three years and inspect the heatsink fan for dust buildup; the processor itself has no user-serviceable parts and does not require scheduled replacement.

What limit appears first when all 24 cores run sustained workloads at 2.1 GHz?

The 185 W thermal design power is the first constraint; the cooling solution must dissipate that heat continuously or the CPU will throttle below its base frequency.
