If it was possible to achieve a level close to top human players with computing resources available in 1992, hardware of equivalent cost can probably handily beat any human in 2020. So no big lab is going to spend any time on hammering home that point, because they're looking for interesting research problems, like games where no program plays at human level yet. If you want to see how well computers play using consumer hardware, maybe try https://www.gnu.org/software/gnubg/ https://www.gnu.org/software/gnubg/ I have no idea whether a rating of 2000 is superhuman or not.
