Second in the RTX 5090 series — but the GPU sits ~23% idle. This Go life-and-death solver is CPU-bound, and the prime suspect for the gain is the Core Ultra 9's 3 MB-per-core L2 cache — 12x the 2014 Xeon's.

A 2023 paper solved a tiny 7x7 Go position on a 12-GPU cluster. I re-ran the exact same solver on a single RTX 5090 — identical proof, and a clean benchmark of what a decade of…
