This brings up the question of why NNs that require both a GPU and a CPU are even included in a Single Version list, as they require two processors, not one. A normal pc will have several CPU cores but only one GPU, so if a program is mostly GPU-bound then limiting it to only 1 CPU core is only a minor restriction. I imagine there are very few users with just one CPU who also have a decent GPU. I'm glad you include the NNs on your rating list, just not on the Single Version list.

It is a tricky issue. In CCRL we currently treat the GTX1050 and below as single CPU, and the RTX2080 as multiple CPU. I'm not sure there is a right or wrong answer. In reality the GTX1050 is probably in between 1 and 2CPU. But your point is that all GPU engines should be treated as multi-CPU because they use both CPU and GPU ? Definitely a strong argument for that. GPU testing is a bit of a nightmare !

But is the CPU version of Leela on the list? That obviously can be single CPU with no fudging.

We slowed down our graphic cards to get a ratio near 1 in comparison to 1CPU Stockfish. This is the way we tried to solve this issue (this is our standard). And here for instance for some faster cards we even use 1CPU for NN engines. This is not always easy as Scorpio uses per default all threads of the pc and Stoofvlees is a hybrid engine using 4 threads of my quad but with only 25% of the CPU.

Yes.
