28-core Xeon workstation CPU

The Intel Xeon W-3275M is a 28-core processor built for single-socket workstations that need up to 56 threads. It targets professionals running multi-threaded workloads such as rendering, simulation or large-scale data analysis. The chip operates at a 2.5 GHz base frequency with a 4.4 GHz maximum turbo.

LGA 3647 socket installation

The CPU drops into an LGA 3647 socket using the standard server retention mechanism; no soldering or special tools are required. Because the part is an OEM tray unit, it ships without a cooler or retail box. Installers must supply a compatible 205W-rated heatsink and apply thermal paste before powering the system.

205W TDP defines cooling and chassis

The processor draws up to 205 watts, so the workstation must provide a single-socket motherboard and cooling solution rated for that thermal envelope. Dual-socket boards and compact enclosures that cannot dissipate 205W are unsuitable. Buyers needing a lower-power chip or a multi-socket platform should look elsewhere.

Questions sur cet article

How can I verify the Xeon W-3275M is running at its 4.4 GHz max turbo frequency after installation?

Monitor core clocks under load using system utilities; all 28 cores should reach 4.4 GHz when thermal and power headroom allow.

What ships with the tray processor and what must be sourced separately?

The CPU arrives in an anti-static clamshell protector; a compatible LGA 3647 motherboard, cooling for 205W TDP, and system memory must be purchased separately.

Which Xeon W-3275M version suits a single-socket Mac Pro 2019 upgrade?

This 28-core 2.5 GHz model with 205W TDP is the Apple-authorised processor for the 2019 Mac Pro; ensure the workstation firmware supports the 38.5 MB L3 cache configuration.
