It takes even more tuning as it is still a NUMA box. On the 4-way and 2-way boxes memory is local, 1 hop or 2 hops away. This adds to that. 2. it won't be 2x faster as nobody scales perfectly. IE Crafty would probably be about 1.7X faster, more or less depending on lots of things. That is not enough to make up for the apparent difference in playing strength between Shredder and Hydra. IE Hydra appears to be 200+ points stronger based on a final result of 6-2. 1.7X faster won't get 200 points for Shredder... These machines are not bad. There are _several_ companies with 8-way boxes ready to go. I ran on one at least 6 months ago. AMD has had one in their development lab since well before the last CCT event...
