Very interesting this test.
The picture for the test was 512px using DPMPP_2M + SGM_UNIFORM in ComfyUI.
As you can see Q8 is much slower than FP8, but it has the best gpu freshy temp and great ram usage.
Q4_1 is 15 sg slower than FP8 but the ram usage is ridiculous!
Q8 has the best gpu temp but it is a turtle.
My pc : i7920 2.66ghz overclocked 3.8ghz , 24 gb ram, 1070ti 8gb vram.
It is a tricky decision if you want your gpu fresh, fast renders, ram usage or max quality.
This picture was render with Q4_1, it has outstanding quality (1024px) 20 steps.
This princess was render with Q8, and took 8 min
