Purpose-built server processor

The Intel Xeon Gold 5418Y is a 24-core, 48-thread CPU designed for dual-socket server platforms using the LGA 4677 socket. It targets workloads that benefit from high core counts and large memory capacity, such as virtualisation, database hosting and compute-intensive applications. The processor supports up to 4 TB of DDR5 memory across eight channels.

Thermals and power profile

With a thermal design power of 185 W the chip requires robust cooling; no cooler is included in the package. Base frequency sits at 2.0 GHz and can reach 3.8 GHz under turbo, so sustained loads will draw near the rated power. The 10 nm Sapphire Rapids architecture balances density and efficiency for continuous operation in rack environments.

Build and connectivity implications

The package delivers 80 lanes of PCI Express 5.0, enabling direct attachment of multiple high-speed accelerators, storage controllers or networking cards without bandwidth bottlenecks. Eight memory channels demand a motherboard with a full complement of DIMM slots to realise the 4 TB limit. Scalability is limited to two-socket configurations.

Questions about this item

How is the LGA 4677 processor seated and what alignment step is often missed?

Align the notches on the 24-core chip with the socket keys, lower it vertically without tilting, then engage the retention lever fully; the common error is partially closing the lever before the package sits flat.

What cooling upkeep does the 185 W TDP demand over time?

Replace thermal paste every two to three years and verify the heatsink fan spins at rated RPM; dust buildup on fins reduces dissipation and can trigger throttling on this 10 nm part.

At what point does the 3.8 GHz turbo ceiling limit sustained all-core workloads?

When all 24 cores run AVX-512 the package hits its 185 W power budget, forcing frequencies below the single-core 3.8 GHz maximum to stay within thermal limits.
