Trying to precisely >quantify how large that advantage is is not so easy... Honestly, I am not so sure how big that advantage is. Hydra runs on 16 processors instead of 4, so for the same nps it is less efficient. In addition, his cards can't probe the hash table in the last few ply which also leads to a lot of duplicate work. I have a suspicious Hydra gets a speedup of 4 or so . . . anthony
