Intel Xeon W7-2595X 26-core server processor

The Intel Xeon W7-2595X is a 26-core, 52-thread server CPU built on the Sapphire Rapids architecture. It operates at a 2.8 GHz base frequency and reaches a 4.8 GHz maximum turbo frequency with Intel Turbo Boost Max Technology 3.0. The processor includes 48.75 MB of L3 cache and supports DDR5 4800 memory across four channels. It is designed for single-socket workstations handling rendering, simulation and virtualization workloads.

Compatibility checks for LGA 4677 platform

Verify that your motherboard uses the LGA 4677 socket and a chipset that supports this Xeon W series processor. Confirm the board provides DDR5 slots wired for quad-channel operation up to the 2 TB maximum capacity. Ensure the BIOS version listed by the board vendor includes support for the Sapphire Rapids core. The CPU offers 64 lanes of PCI Express 5.0; check that your required expansion cards and storage devices match the available lane allocation.

Thermals noise and power draw in normal use

The processor has a 250 W thermal design power and a 300 W maximum turbo power rating. A cooling solution rated for at least this thermal load must be sourced separately as none is included. Under sustained multi-core workloads the chip will draw power close to the turbo limit, so case airflow and cooler capacity should be planned accordingly. Acoustic output will depend entirely on the third-party cooler and fan curves selected by the builder.

Questions about this item

Does the BX807132595X box include a cooler or do I need to buy one separately?

The processor is sold without a cooling device; a compatible LGA 4677 cooler rated for at least 250 W TDP must be purchased separately.

Should I choose this 26-core 2.8 GHz model or a higher-clocked variant for single-threaded workloads?

This 26-core model reaches 4.8 GHz with Turbo Boost Max 3.0 and 4.6 GHz on a single core, so it already delivers the highest single-thread speeds in the W7-2595X line.

What does the 4.8 GHz Turbo Boost Max 3.0 figure mean once the CPU is installed in a workstation?

It is the maximum frequency one core can hit under light load when power and thermal headroom allow; sustained all-core speeds will be lower and depend on your cooling solution.
