Intel Xeon w5-3425 OEM Workstation Processor (PK8071305082100) – 12-Core, 24-Thread, Up to 4.6GHz, LGA 4677, 30MB cache

The Intel Xeon w5-3425 (PK8071305082100) is an LGA 4677 workstation processor with 12 cores, 24 threads and boost clocks up to 4.6GHz. Built on Xeon W-3400 (Sapphire Rapids), with 30MB cache, it is aimed at 3D artists, engineers, video editors and AI developers running heavy multi-threaded workloads.

Workstation core counts for renders, simulations and AI.

More Cores, Memory Channels and PCIe for Professional Work

Rendering, simulation, large code builds and local AI work scale with cores, memory bandwidth and PCIe lanes. Mainstream desktop platforms top out at dual-channel memory and limited lanes, which caps how many GPUs, NVMe drives and network cards you can run at full speed.

The Intel Xeon w5-3425 moves to the LGA 4677 workstation platform: 12 cores, DDR5-4800 ECC RDIMM, 8-channel memory and 112 PCIe 5.0 lanes. Multi-GPU rigs, large memory footprints and fast storage arrays run without the bottlenecks of a desktop platform.

Cores, Clocks and Cache in Practice

With 12 cores, 24 threads, up to 4.6GHz and 30MB cache, the Intel Xeon w5-3425 handles renders, simulations and multi-GPU compute with headroom. Power is rated at 270W TDP.

Platform and Connectivity

The LGA 4677 socket supports DDR5-4800 ECC RDIMM, 8-channel and 112 PCIe 5.0 lanes. A discrete graphics card is required for display output.

Setup Instructions

How to Install the Intel Xeon w5-3425

1. Check your motherboard uses the LGA 4677 socket and update its BIOS to a version that supports the Xeon w5-3425.
2. Open the socket retention mechanism, align the CPU’s markings with the socket and lower it in without force.
3. Apply thermal paste if needed and install a capable air or liquid cooler – no cooler is included.
4. Install a discrete graphics card, boot into BIOS, confirm memory runs in all channels and install the latest chipset drivers.
