TCECs goal is to keep the ratios similar to the AlphaZero paper, not price or power or other benchmark. Increasing the hardware of one would require an increase of the hardware of the other. But, the hardware is donated, so it's hard to be too critical.
But why are we comparing used 2021 prices when these hardware weren't purchased in today's market? Especially when GPUs are 1.5-2x MSRP right now. Even very old GPU prices are insane. I recently sold a 980ti near what I purchased it new. 4669v4 MSRP was $7k, so they are not far off. The V100 is pretty dated too as it is from 2017, and doesn't have FP16 which is heavily used by Leela. For this and several other reasons, a single 3090 is actually faster than 4x v100s according to their own bechmarks[1]. A single v100 is approximately equal to a 3080 or 2080ti in performance.
Maybe you should also checkout the CCCC[2] hardware which is even stronger for both: 2x A100 vs 2x AMD EPYC 7H12
