AMD Ryzen Threadripper PRO 5965WX Workstation Processor

Zen 3 · Chagall · Socket sWRX8 (WRX80) · OEM Tray
24-Core / 48-ThreadUp to 4.5 GHz128 MB L3 Cache8-Channel DDR4 ECC

The AMD Ryzen Threadripper PRO 5965WX is a Zen 3 (Chagall) workstation processor with 24 cores and 48 threads, a 3.8 GHz base clock that boosts to 4.5 GHz, 128 MB of L3 cache and full 8-channel DDR4-3200 ECC memory support — built for professional workstations that need huge memory and PCIe bandwidth alongside high per-core clocks. Supplied as an OEM tray unit (part number 100-000000446) without a cooler. Typically in stock with fast delivery across Cyprus.

Compatibility — read before you buy
This is a workstation processor for the AMD Socket sWRX8 (WRX80 chipset) platform — it requires a WRX80 motherboard and is not compatible with consumer AM4/AM5 boards. It supports 8-channel registered ECC DDR4-3200 (RDIMM/LRDIMM) up to 2 TB and provides 128 PCIe 4.0 lanes. It ships without a cooler, so use a compatible sWRX8 workstation air or liquid cooler rated for its 280W TDP.

Frequently Asked Questions

What motherboard does the Threadripper PRO 5965WX need?
It requires an AMD WRX80-chipset motherboard with the sWRX8 socket — not consumer AM4/AM5 boards. These boards provide the 8 memory channels and 128 PCIe lanes the CPU supports.
Does it come with a cooler?
No. This is an OEM tray unit supplied without a cooler. Use a compatible sWRX8 workstation air or liquid cooler rated for its 280W TDP.
Does the Threadripper PRO 5965WX have integrated graphics?
No. It has no integrated graphics, so a discrete workstation or gaming graphics card is required for display output.
Why choose Threadripper PRO over a standard Ryzen?
Threadripper PRO adds 8-channel ECC memory (up to 2 TB), 128 PCIe 4.0 lanes and PRO management/security features that mainstream AM4/AM5 Ryzen chips do not offer — essential for memory- and I/O-heavy professional workstations.
Singular Expert Insight
The Threadripper PRO 5965WX balances 24 high-clocked Zen 3 cores with the full 8-channel memory and 128 PCIe lanes of the WRX80 platform — ideal for studios that need strong per-core speed plus heavy parallelism and large memory. For more cores the 5975WX (32-core) and 5995WX (64-core) scale up on the same platform; the 5955WX (16-core) costs less. Pair it with registered ECC DDR4 memory across all eight channels for maximum bandwidth.

Buyer's Guide

Buy it if
You run demanding professional workloads and want 24 cores with 8-channel ECC memory, 128 PCIe 4.0 lanes and PRO features on the WRX80 platform.
Skip it if
You want a gaming or mainstream desktop CPU (a Ryzen 9 is far cheaper), or you do not need the memory and PCIe capacity of the WRX80 platform.
Also consider
The Threadripper PRO 5975WX (32 cores) or 5995WX (64 cores) for more compute, or the 5955WX (16 cores) for less.
