Intel Xeon W9-3475X 36-core server processor

The Intel Xeon W9-3475X is a 36-core, 72-thread server processor built on the Sapphire Rapids architecture. It operates at a 2.2 GHz base frequency and reaches a 4.80 GHz maximum turbo frequency. The CPU features 82.5 MB of L3 cache and an 8-channel DDR5 4800 memory controller.

Suited for multi-threaded workloads on LGA 4677

This processor targets workstations and servers that need high core counts and large memory bandwidth for rendering, simulation or virtualization. Buyers who need a lower thermal design power or a consumer desktop socket should consider other options.

360 W maximum turbo power defines cooling

The processor has a 300 W base power and a 360 W maximum turbo power, requiring a cooling solution and voltage regulation capable of sustaining that thermal load under full turbo operation.

Questions about this item

Which socket and power rating must the motherboard support for the Xeon W9-3475X?

The processor uses an LGA 4677 socket and has a base power of 300 W with a maximum turbo power of 360 W, so the board must be rated for at least 360 W.

What is the correct installation sequence for the LGA 4677 processor and the step often missed?

Open the socket lever, align the notches on the CPU with the socket keys, place the chip gently without pressure, close the lever, then secure the independent loading mechanism; the step often missed is torquing the ILM bolts in the specified cross pattern.

When should the thermal interface material be replaced on this 36-core Xeon?

Replace the thermal paste whenever the cooler is removed or if temperatures rise above normal under sustained 360 W loads; a high-quality paste rated for server TDPs is recommended.
