Xeon W7-2595X 26-core server processor

The Intel Xeon W7-2595X is a 26-core, 52-thread server CPU built for single-socket workstations. It runs at a 2.8 GHz base frequency and reaches a 4.8 GHz maximum turbo frequency using Intel Turbo Boost Max Technology 3.0. The LGA 4677 package includes 48.75 MB of L3 cache and a quad-channel DDR5-4800 memory controller supporting up to 2 TB of RAM.

Suited for heavy parallel workloads.

This processor targets professionals who need high thread counts for rendering, simulation, code compilation, or dense virtualisation on a single-socket platform. The 64 lanes of PCI Express 5.0 provide ample bandwidth for accelerators and fast storage. Buyers who require multi-socket scalability should look elsewhere because the part is limited to 1S operation.

LGA 4677 socket and 250 W base power define

The processor fits only motherboards with the LGA 4677 socket and a thermal solution rated for at least 250 W base power, with headroom for 300 W maximum turbo power. No cooler is included in the tray package. Quad-channel DDR5-4800 is the supported memory standard, and the 10 nm manufacturing process underpins the 26 cores and 48.75 MB cache.

Questions about this item

Does this Xeon W7-2595X require a motherboard with an LGA 4677 socket?

Yes, it installs only in an LGA 4677 socket; the processor is not soldered and sits in the socket on the PCB.

What is the correct installation step for the LGA 4677 socket that people often miss?

Align the processor using the socket keying notches, lower it straight down without pressure, then engage the independent loading mechanism lever to secure it evenly.

When will the thermal interface material on this 250 W TDP processor need replacement?

Reapply thermal paste every two to three years or whenever the cooler is removed, as the 250 W base power and 300 W max turbo power accelerate paste drying.
