Which is better for 3D rendering?

The 5975WX has 8 more cores, which helps in heavily multithreaded renderers. The 7965WX wins on single-thread speed, so it is better for lighter or mixed workloads.

Which is better for gaming?

The 7965WX. Its 5.3 GHz boost and Zen 4 cores give higher frame rates, though a mainstream desktop CPU is cheaper for gaming alone.

Can I use the 7965WX in an sWRX8 motherboard?

No. The 7965WX needs socket sTR5 and a new motherboard. The 5975WX needs sWRX8.

Which supports more memory?

The 5975WX supports up to 2TB of ECC DDR4. The 7965WX supports up to 1TB of ECC DDR5, which is faster per channel.

Is the 7965WX worth the extra cost?

For a new build, yes, because of DDR5, PCIe 5.0, and higher clocks. If you already own an sWRX8 board, the 5975WX avoids a full platform swap.

The 5975WX has a 280 W TDP versus 350 W for the 7965WX, so it needs less cooling capacity.

AMD Ryzen Threadripper PRO 5975WX vs AMD Ryzen Threadripper PRO 7965WX

Buy the 7965WX for new builds: it is faster per core, uses DDR5, and runs on the current sTR5 platform with PCIe 5.0. Buy the 5975WX only if you already own an sWRX8 board and need 32 cores or up to 2TB of DDR4 ECC memory. No prices were provided for either chip, so compare live store prices before deciding.
