EDIT: FWIW, their own bench isn't even accurate anymore. My 780 does better than a 7970 on their current core. (app) ID: 32376 · Rating: 0 · rate: / Reply Quote

No, because even Titan get slowed down to "only" 1/3 its SP performance in DP. CPUs can do it at 1/2 rate, but it doesn't get any better than this. In DP you always loose performance for increased precision, which is a really bad idea if your calculations are precise enough in SP.
