Verdict

Which should you buy?

Winner overall

The EPYC 9755 wins overall with far more cores and cache for heavy server workloads, leaving the older Threadripper 3990X in a different performance class.

Best value

For budget buyers, the Threadripper 3990X is the smarter pick if you need high core count on a single-socket platform without the EPYC's premium cost.

When the other wins

The Threadripper 3990X is the right choice for a home workstation running multithreaded creative apps where power and cooling limits make the 500W EPYC impractical.
