Intel Xeon W9-3575X 44-core server CPU

The Intel Xeon W9-3575X is a 44-core, 88-thread processor built for single-socket workstations. It runs at a 2.2 GHz base frequency with a maximum turbo of 4.8 GHz and provides 97.5 MB of L3 cache. The chip fits the LGA 4677 socket and supports eight-channel DDR5 4800 memory up to 4 TB capacity.

For heavy multi-threaded workloads only

This processor suits users running large-scale rendering, simulation or virtualisation tasks that scale across 44 cores and 112 PCIe 5.0 lanes. Buyers who need multi-socket scaling, lower power draw or a smaller core count for single-threaded applications should look at something else.

Verify socket, memory, power and cooling

Confirm your motherboard uses the LGA 4677 socket and supports a 340 W base TDP with headroom for 408 W max turbo power. Ensure the board provides eight DDR5 slots for full memory bandwidth. A compatible cooling solution must be sourced separately as none is included.

Questions about this item

What motherboard socket is required for the Xeon W9-3575X?

The processor fits the LGA 4677 socket, so a motherboard with that socket is needed.

Can the W9-3575X share a platform with a second Xeon processor?

The chip is rated for 1S only, meaning it operates in single-socket systems and does not support multi-socket configurations.

How can I confirm the CPU reaches its 4.8 GHz Turbo Boost Max frequency?

Monitor single-core clock speeds under load with a tool such as Intel XTU or HWInfo; sustained readings at 4.8 GHz indicate the feature is active.
