But better evaluation gives you asymptotic speedups. You can give Stockfish several times its computation (which is already a lot, I mean, 64 threads, come on) and it doesn't make good use of it since it just runs into the search wall. If you gave Stockfish the equivalent in CPU power (and I'm not sure this is a fair hypothetical since part of the appeal of NNs is that they have such efficient hardware implementations, so it seems unfair to then grant a less efficient algorithm equivalent computing power by fiat), I'm not sure it would be restored to parity or superiority.
