If we consider that Hydra probably peaks at 200 million nodes/s and the average speed is say 150 million nodes/s, then if we remember that doubling of speed adds 30 elo points in long games; If i remember correctly, then Brutus was running at 20 million nodes/s (peaking at 30 million nodes/s) on a dual machine, so if we do a a little math here we have: 150 divided by 2=75, 75 devided by 2=32.5 which means that Hydra on a regular dual running 20 million nodes/s would be roughly 80 elo weaker than the beast they had playing Adams. If we say even that doubling of speed gives you 70 elo points it would still only be roughly 160 elo weaker (at that time control, they used in the Adams match). Considering that Hydra running 150. million nodes/s is rated 3100+ then it would still be a lot stronger than your average pc program. Is this fairly accurate or am i way off?
