This is more of a FYI.
This is to point out Tensor cores (Nvidia mixed precision compute branding as I did a search on it) do for denoising. This is a topic over GPU denoising using Nvidia hardware on KeyShot 9. The denoising feature is really a must, it also demonstrated that other than Nvidia solution can take advantage of. The entry level 5500XT did a good job on the Contemporary Bathroom Interior for my budget. I wasn't able to test it with my WX4100 as I didn't know that feature before on KS9 when I replaced it with the current 5500XT.
Below is 3700x CPU rendering and note the time
This with CPU plus GPU effects enabled
Giving credit on how the 5500XT delivers.
