AMD Ryzen Threadripper 7980X vs AMD Ryzen Threadripper PRO 3995WX
Buy the Threadripper 7980X for a new workstation: it is a newer Zen 4 chip with PCIe Gen5, DDR5 and a 5.1 GHz boost, and it fits current sTR5 boards. The PRO 3995WX only makes sense if you already own an sWRX8 platform, since it is Zen 2 on DDR4 with a 4.2 GHz boost. No prices were provided for either chip, so compare live store prices before deciding.

What reviewers say
AMD Ryzen Threadripper 7980X
Owners treat the 7980X as a workstation chip: they praise its all-core throughput in rendering and encoding and accept the platform cost. Complaints center on heat, power draw and gaming performance that trails cheaper consumer CPUs.
- Multi-core performancePraisedOwners say all-core rendering and encoding jobs finish far faster than on mainstream CPUs.
- Heat and powerCriticisedSustained loads push the 350 W chip hot, requiring large coolers and strong case airflow.
- Platform costCriticisedsTR5 boards and quad-channel DDR5 kits add a lot to the total build price.
Questions and answers
- Which is faster for rendering?
- The 7980X. Same core count, but Zen 4 cores and a 5.1 GHz boost beat Zen 2 at 4.2 GHz in most render and encode workloads.
- Does the 3995WX work in an sTR5 motherboard?
- No. It uses socket sWRX8, so it needs a WRX80 board. The 7980X uses sTR5 and will not fit either.
- Which handles more memory?
- The 7980X, at 256GB of DDR5 with ECC. The 3995WX listing caps at 32GB of DDR4, though its eight channels help bandwidth.
- Is the 7980X worth the extra cost?
- For a new build, yes, because you get a current platform, PCIe Gen5 and faster cores. For an existing sWRX8 owner, a new board and RAM often outweigh the gain.
- Do either have integrated graphics?
- No. Both need a discrete GPU.
- Which runs cooler?
- The 3995WX on paper, at 280 W versus 350 W. Real temperatures depend on the cooler and the sTR5 or sWRX8 mounting.
