AMD Ryzen Threadripper 7980X vs AMD Ryzen Threadripper PRO 3995WX
For a new 64-core workstation build, the Ryzen Threadripper 7980X is the better buy. It is a Zen 4 part on sTR5 with PCIe 5.0, DDR5-5200 and a 5.1 GHz boost, while the Threadripper PRO 3995WX is Zen 2 on sWRX8 with PCIe 4.0 and DDR4-3200. The 7980X is the faster chip per core and per watt-class, but it needs a new sTR5 board and DDR5.

Questions and answers
- Which is faster for rendering?
- The 7980X. Zen 4 cores plus a 5.1 GHz boost give it a clear lead in most CPU renderers despite the same 64 cores. The 3995WX's 256 MB L3 cache narrows the gap in some large-scene workloads.
- Do they use the same motherboard?
- No. The 7980X needs an sTR5 board; the 3995WX needs sWRX8 (WRX80). Neither fits the other's socket, so the platform cost differs.
- Which has more memory bandwidth?
- The 3995WX, with up to eight DDR4 channels. The 7980X uses four DDR5-5200 channels, which is faster per channel but fewer lanes.
- Is the 7980X worth the extra cost?
- If you are building new, yes: it is the only one of the two on a current platform. If you already own an sWRX8 board, the 3995WX avoids a full rebuild.
- Which runs cooler?
- The 3995WX at 280 W TDP versus 350 W for the 7980X. Both need large coolers; the 7980X needs more headroom.
- Does either have integrated graphics?
- No. Both need a discrete GPU.
