Your still missing the point, even if deactivated. It still had an unnatural group of ROPs.The 1080 ti is based on GP102 die used by the titan x Pascal GPU which has all 96 ROPs (and 2 SM desactivated), they desactivated 8 ROPs for the 1080 ti (not more SM) + reduced the memory interface.
The 3080 ti is based on 3090 die which has 128 ROPs, here it's 16 desactivated.
The 1080ti could show that some GP102 had deffect at ROPs level and why the 1080 ti differ only at this level compared to the titan x Pascal.
So anything is possible when it comes to Mark Cerny. You guys refuse to believe anything that different.
Just like when people were saying PS5's FPU was cut down, which turns out it is actually densely compact and still is 256.
