AMD Ryzen Threadripper PRO 5955WX vs AMD Ryzen Threadripper PRO 5975WX

The 5975WX is the stronger workstation chip: 32 cores and 64 threads against 16 and 32, plus 128 MB of L3 cache versus 64 MB, on the same sWRX8 platform and the same 280 W envelope. Both top out at 4.5 GHz boost and both give you 128 PCIe 4.0 lanes and 8 memory channels, so the 5955WX only makes sense if you want fewer cores and higher base clocks for lightly threaded work. Owners and reviewers treat the 5975WX as the render-farm and simulation pick and the 5955WX as the budget entry to the platform.

• Choose the Ryzen Threadripper PRO 5955WX if your work is mostly single-threaded or lightly threaded and you want the cheapest way onto the sWRX8 platform with 128 PCIe lanes.
• Choose the Ryzen Threadripper PRO 5975WX if you render, simulate, compile or run VMs and want double the cores, double the threads and double the L3 cache for the same power draw.
