32-Core Xeon for Single-Socket Workstations

The Intel Xeon W7-3565X delivers 32 cores and 64 threads in an LGA 4677 package built for single-socket platforms. Its 2.5 GHz base clock and 4.8 GHz maximum turbo frequency target compute-intensive workloads such as simulation, rendering and large-scale data analysis. The 335 W thermal design power demands robust cooling suited to workstation chassis.

82.5 MB L3 Cache and 4 TB Memory Ceiling

A shared 82.5 MB L3 cache reduces latency across all cores when datasets fit, while the eight-channel controller at 4800 MHz feeds up to 4 TB of system memory. Workloads exceeding that capacity or requiring multi-socket scaling will hit the hard 1S-only limit and must move to a different platform tier.

PCIe 5.0 with 112 Lanes for High-Bandwidth I/O

The processor exposes 112 lanes of PCI Express 5.0, enabling dense GPU, storage and networking configurations without lane contention. Systems needing more aggregate bandwidth than 112 lanes provide, or requiring PCIe 6.0 signalling, cannot be satisfied by this CPU.

Questions about this item

Will the LGA 4677 socket on this Xeon W7-3565X fit my existing LGA 4677 motherboard?

The processor uses the LGA 4677 socket, so it installs in any motherboard with that socket.

How can I verify the 32 cores and 64 threads are active after installing the Xeon W7-3565X?

Check the operating frequency of 2.5 GHz and max turbo of 4.8 GHz in BIOS or OS tools to confirm the 32-core, 64-thread configuration is detected.

Does the Xeon W7-3565X box include a cooler or do I need to buy one separately?

The supplier notes the cooling device is not included; only the processor is supplied.
