for the curious
gtx 670
7970
not to mention 1302 on the gtx 7970 was completely stable and not burning the card up where as 1250mhz on the radeon tended to crash every now and then in bf3

how the hell you get P9106 with 1250 on the core?? when i get P9074
with a mild oc of 1150 on it??
and btw your cpu have 200mhz extra on the 670 so that helps the score to rise better on the 670 bench.. suicide run? lol

I surely blows your 670 out of the water with a lil bit more... XD

I think is time to spent money on the cpu so you can add extra performance on top of that so your shinny 670 performs by good numbers..

http://www.guru3d.com/article/geforce-gtx-670-review/24 Here with 1200+ core clock in 1080p and 1400p we see 6 fps and 5 fps increase. With so good overclock i expect better scale in performance

How is that poor scaling though? A 17% overclock translated to a 11% increase in fps. And here you see a 20% overclock equated to a 13.8% increase in fps. That seems like fairly standard scaling to me. Based on the Guru3D 7950 review, it only scaled 14% better (12.5% increase in fps with a 20% overclock). tongue.gif


I made another good post here comparing the 7950 to the 670 both under full overclock. It should be pretty helpful in answer the original posters question thumb.gif

ok lets talk about scaling

about 33% increase in fps

So 56% overclock (800-> 1250) netted 36% average performance increase across all resolutions? How is that better than 17->11 and 20->14?

that is the volt fanboy:p

the core clock is 1150 memory is 1575

Yeah, lets do. They overclocked the card by 43% (from 800c stock, to 1150c) but only saw a 33% increase in fps. That's a .76% fps increase for every 1% overclock.

Compared to this reference 670 here, which overclocked by 20% and saw a 13.8% increase in fps. That's a .69% increase in fps for every 1% overclock.

In conclusion: There's a .07% per 1% overclock difference between the 7950 and 670. That's a percent difference of only 10% (ie, 7950 scales 10% better than 670). Overclock scaling is just a small part of the total equation anyways. The fact that the 670 can hit a higher average max-overclock makes up for this small 10% difference in scaling. That's why at max overclocks the 670 is ~4-7% faster in game benchmarks, and ~11% faster in synthetic benchmarks when both cards are overclocked.

Another note here: AMD is foolish for releasing their cards at such a low stock core speed when they have so much overclocking headroom. The 7950 should have been released at 950c for the stock reference model. This would have made them look a lot more competitive to the uneducated buyer that only looks at stock speed benchmarks (in which the 670 murders the 7950 when both are at stock speeds). Silly AMD, trying to set the bar low so they could easily top it later if they needed to tongue.gif

I expected this but good to see the numbers. Nice post.

GTX 670 don't got nothing on the HD7950 for those that know how to over clock.

Sigh, please read this entire thread, specifically this post before making comments like that (which are backed up by nothing). Why even say that if you aren't willing to prove your position with facts? I presented so much evidence through out that other thread, where is your evidence?

Core Clock: ~1300 MHz 30%

15% fps !!!!!!!!!!!!!! even that gtx680 was a golden chip it hit 1300

gtx670 is the little brother and he will act like his big brother;)

wait for the guru gtx670overclock guide and you will see

Yes, you are correct, I misread the chart. However, according to SeanPoe's calculations, the point still stands: 7950 just 10% better at scaling than 670. It's a little better, but not "ZOMG!!! Amazing scaling!1!1!1", like some people make it sound here. I still didn't see the proof that clock for clock, 7950 is faster than 670.
