680 670 vs 7970 7950 Overclocked

[redeemer]

Hey guys current updated information only which architecture is kicking out more performance when overclocked. I just want your thoughts very curious to see what you opinions are.

It really depends on how much you want to spend.

The price to performance for the 7950 is REALLY nice, now that they got another price cut.

It also depends on what games you are playing.
If you are playing bf3, then go for the 680 at 500, 670 at 400 or 7950 at 330, exclude the 7970.

For sure prices are great right now, i assume that anybody you buys a video cards would probably want to buy the best card in the segment considering we are talking about two top tier cards from each camp.

This review uses a limited set of benchmarks, but its max OC vs max OC:

Quote:
"Even without being able to increase the voltage on the MSI GeForce GTX 680 Lightning, it was able to keep up with the Radeon HD 7970 GHz Edition overclocked. The Overclocked MSI GeForce GTX 680 Lightning was faster in 3 of our tests while the Overclocked AMD Radeon HD 7970 was faster in the other 4 tests. Once voltage tweaking becomes available the MSI GeForce GTX 680 Lightning will most likely perform faster than the AMD Radeon HD 7970 in two more of those tests"

Of course, Overclockers Club tests all of their cards overclocked vs. overclocked. I hate their charts, they're so hard to read, and there is no summary chart, which would be nice.

They got dead on even between the GTX 680 reference model and the Sapphire 7970 Toxic overclocked in BF3 at 1920x1080:

I suppose you could go through those charts and come up with some conclusions that serve your inquiry if you wished to do the work.

I assume you've read the Anandtech review of the EVGA 680 Classified, which is EVGA's most ambitious 680 model so far. You get a pretty good sense there of the absolute limits of the GK104: the 680 classified has 4GB of RAM and can overclock like an absolute beast. So its limits tend to come from VRAM bus/bandwidth (as opposed to sheer quantity) or from the GPU itself. Anyway the review is here: http://www.anandtech.com/show/6096/evga-geforce-gtx-680-classified-review/9 There are some very instructive charts with the latest drivers comparing the 7970 GHz Edition to various 680 profiles. But that chart won't give you the greatest sense of what a truly OCed 7970 or 7970 GE (not that they're particularly different on manual OCs) can do, nor will it tell you much about the 670 or 7950.
