Full published specifications for the AMD Ryzen Threadripper PRO 7985WX 64-Core Workstation Processor, as supplied. Confirm platform support before ordering: compatibility validation against your specific server model is part of every order.
Where the Ryzen Threadripper PRO 7985WX 64-Core is deployed
- Capacity expansion on existing systems
- Like-for-like replacement and spares holding
- New build-outs specified around a fixed platform
Who this part is for
- Procurement sourcing a like-for-like replacement under fault
- Integrators building to a specified processor model and stepping
- Teams upgrading compute inside an existing chassis rather than replacing it
Questions buyers ask about this part
Will the 7985WX 64-Core drop into my board?
It needs Socket sWRX8 / sTR5 and a board that supports Zen 3 / Zen 4 Workstation. Socket is absolute (a processor for another socket will not fit whatever else matches), and the board also needs a BIOS level that recognises this stepping. Send us the server or board model and we will confirm both before you order.
What cooling does the 7985WX 64-Core need?
It is a 350W part, so the chassis has to be rated for that at the ambient temperature you run. Dropping a 350W processor into a chassis specified for a lower-wattage bin will throttle under sustained load rather than fail outright, which is harder to diagnose. Tell us the platform and we will check the thermal rating and whether a different heatsink is required.
How many cores is 7985WX 64-Core, and does that affect licensing?
64C / 128T. Per-core licensing on databases and some hypervisors means the core count is a cost decision as much as a performance one: a higher-clocked part with fewer cores is often cheaper to run overall. Tell us what you are licensing and we will quote both ways.
Is this AMD part genuine, and is the warranty intact?
Yes. We supply through authorized distribution only, so the part carries the full AMD manufacturer warranty and its firmware update path stays supported. No grey-market stock, no re-labelled drives, no voided warranties.
Do you offer volume pricing and accept purchase orders?
The listed price is per unit and indicative; tiered pricing applies at quantity. We accept purchase orders from qualified businesses, government and defence agencies, and educational institutions, with net terms and consolidated invoicing available. Email the quantity you need and we will come back within 48 business hours.
