When you compare the 7870 vs. the 7970 ... i cant help but notice that somethings really wrong with the 7970 ...
The 7870 has 1280SPs while the 7970 has a total of 2048SPs ... i.e the 7970 has 60% more SPs than the 7870 ... and mem and core clocks sort of even out ... cos 7870 has has a higher core clock while the 7970 has higher mem clock ...
but when you compare the performance ... the 7970 is only around 25% faster on average than the 7870 ... i feel there seems to some kinda bottlenecking ... maybe ROPS ... or GCN doesnt scale well ... or may be AMD is purposely doing it ... so when they bring out their next gen cards ... it would look like a huge performance leap ... or may be they'll release a new driver to increase the performance when GTX680 is released
EDIT: i totally forgot that 7970 has 384-bit memory ... ...
