What the heck did Nvidia do to neuter kepler in compute tasks? Does it really save many transistors or wattage?
Probably not.
I'm thinking they nerfed kepler on purpose to force students/professionals/edu to buy tesla cards instead of desktop cards like they did with 580s
They must have learnt it from Intel.
Intel loves do the same thing with lowend CPUs, turning features off on purpose.
Anyways title of thread is really misleading.
In all 3 of the benchmarks where the 7970 is included it's better than the 680.
^ yep, stock 7970 (non ghz ed) beating the 680, by huge amounts.
Also makes you question why in some tests they didnt use any AMD cards to compair.
If there was a card that was "excellent performance per dollar" it would be the 7970.
680 = 133
7970 = 689 (x5 times the 680) (costs ~399$)
7970 1ghz ed = wasnt tested.
Titan = 1309 (x1.8 times 7970) (costs ~999$ = x2.5 of 7970)
71.5 vs 63 = ~13% differnce. (a 7970 1ghz ed would probably be faster)
Price differnce = ~250% differnce.
