Workstation processor for single-socket servers

The Intel Xeon W7-3565X is a 32-core, 64-thread server CPU built for workstations that run heavy compute workloads on a single socket. It targets engineers, researchers and content creators who need high core counts without multi-socket complexity. The processor drops into the LGA 4677 platform and supports up to 4 TB of DDR5 memory across eight channels.

Single-socket constraint with 112 PCIe 5.0 lanes

Scalability is limited to 1S only, so this chip cannot be paired with a second processor in a dual-socket board. If your workload demands multi-socket scaling or more than 112 lanes of PCIe 5.0 connectivity, this part will not meet the requirement. Buyers planning dual-socket servers or larger lane budgets must choose a different processor line.

335 W base power and 402 W max turbo power

The processor carries a thermal design power of 335 W and can draw up to 402 W under Intel Turbo Boost Max Technology 3.0. A cooling solution rated for at least the maximum turbo power is required because no cooler is included in the box. Sustained all-core loads will run near the base power level while bursty single-thread tasks can push consumption toward the higher figure.

Questions about this item

How does the 32-core design with 64 threads perform in a real workstation?

Thirty-two cores and sixty-four threads let you run heavy multi-threaded workloads such as rendering, simulation or large-scale compilation with high parallel throughput.

What does the PCI Express 5.0 interface with 112 lanes actually cap in practice?

The CPU exposes up to 112 lanes of PCIe 5.0, so total platform bandwidth is limited by that lane count and the 5.0 signalling rate per lane.

What does the LGA 4677 socket need for mounting and cooling?

The processor fits an LGA 4677 socket and requires a compatible cooler rated for its 335 W base power or 402 W max turbo power, as no cooling device is included.
