Best AMD Threadripper PRO processors for WRX90 workstations

Top pick: Threadripper PRO 7975WX (32 cores). It's the sweet spot for a WRX90 build — 32 cores and 64 threads at up to 5.3 GHz, so it's fast in single-threaded CAD and simulation work while still chewing through renders and VM stacks. It's also the best-reviewed of the line here and the easiest to find in stock.

Who the others suit:

• 7995WX (96 cores) — if your work is pure throughput: big render farms, CFD, huge compile jobs. You pay a lot for cores you won't use in everyday work.
• 7985WX (64 cores) — the middle ground when 32 cores isn't quite enough but 96 is overkill.
• 7965WX (24 cores) — a sensible step down for mixed workloads on a tighter build budget.
• 7955WX (16 cores) — the entry point to WRX90: full platform, memory bandwidth and PCIe lanes, modest core count.

All are sTR5 and drop into WRX90 boards; the 9000-series (9985WX, 9955WX) are the newer generation if you want the latest silicon.
