Would a single OC'ed 7970 be faster than a 5970?

post #1 of 67
Thread Starter 
Hi,

Not including the extra 2GB VRAM you get with the 7970. Will it be faster than the 5970 2GB (really only 1GB)?

I haven't seen any benchmarks comparing the two.

an overclocked 7970 should compete with gtx 590 and sometimes even beat it while using less power and less heat. So yes it is overall better

Would an overclocked 7970 beat an overclocked 5970?
post #7 of 67
With respect Bob, Passmark's VGA benches are really out dated and not a very good indicator of true performance, since the test resolutions are so low. The rest of their tests are pretty darn good though. There's gotta be some other benches out there that show similar results though. Granted, a 5970 is/was a very powerful card, but a 7970 will best it with roughly 1/2 the power draw, perhaps less. I don't know if the performance difference would really be worth forking out the dough for one though.

As far as i can see, the question isn't bang per buck, it's which is better. The 7970, in those tests, is only beaten by the 590.

HD 5970 can OC dam well too. I would thing as long as HD 5970 is not vRAM limited it will be faster. HD 5970 as almost the same OC headroom as HD 7970.

The best reason to get the 7970 is that you don't need to have crossfire drivers to get proper performance.
