a 1175 Mhz HD 7950 will win more games wrt 1250 GTX 670. It depends on things like exact game level being tested and settings at which tested. Since I wanted to show OC perf I have chosen both cards OC'd.
BF3 Ultra 2X MSAA 2560 x 1600
XFX HD 7950 (1195) - avg 54.2 min 35
BF3 Ultra FXAA high 2560 x 1600
GTX 670 (1234) - avg 58.1 min 36
I am inclined to believe HD 7950 OC is better given its at 2X MSAA whereas GTX 670 is at FXAA high. bandwidth becomes a factor at high GPU clock speeds and very high res with high image quality settings. Even if you want to call it a tie I wouldn't object.
2560 X 1600 MSAA8X + FXAA (marginal HD 7950 OC win or tie)
XFX HD 7950 OC (1195) - avg 79.5 min 30
GTX 670 (1234) - avg 74.5 min 29
Deus Ex - 2560 x 1600 FXAA high
XFX HD 7950 OC ( 900 ) - avg 65.6 min 33
GTX 670 (980 boost) - avg 58.9 min 36
At max OC Deus Ex will be a clear win for HD 7950 OC over GTX 670 OC.
2560 X 1600 FXAA
HD 7950 (800 ) - avg 36.7 fps min 18
HD 7950 OC (900 ) - avg 40.5 fps min 19
HD 7950 OC (1195) - avg 50.5 fps min 19
GTX 670 - avg 44.7 fps min 28
GTX 670 (1234) - avg 49.7 fps min 30
Runs clearly better on GTX 670 given the much better min fps.
HD 7950 - 50 fps
GTX 670 - 42 fps
will be much faster on HD 7950 OC compared to GTX 670 OC given more clock headroom.
Witcher 2 - HD 7950 OC will be faster than GTX 670 OC given that HD 7950 (800) wins against GTX 670 (980 Mhz ).
1080P UBERSAMPLING OFF
HD 7950 - 59
GTX 670 - 54
2560 X 1600 Ultra 4xaa (DX 11 with high res textures)
HD 7950 (1150) - 43
GTX 670 (1280) - 40
faster on HD 7950 OC
Shogun 2 - faster on HD 7950 OC (because of latest patch issue crippling Nvidia perf) .
Out of these 8 games released in the last 12 months GTX 670 OC wins Batman AC clearly. BF3, Skyrim can be called a tie. Deus Ex, Witcher 2, Alan Wake, Crysis 2 are in favour of HD 7950 OC . Older games like Metro and Crysis games (1 / warhead ) run faster on HD 7950 OC than GTX 670 OC . There is no doubt about that.
GTX 670's major advantage will be power consumption. But for a person looking at maximum performance and spending USD 400 on a card I think that is of lesser priority. For those who want perf with lower power GTX 670 is the better option. For those who want maximum performance its better to get a good HD 7950 OC edition card and OC the heck out of it.
