OC: Gaming Performance
Moving on to our gaming performance section, let’s see what our 15% overclock can do for gaming performance. Assuming the 7970GE’s performance continues to scale well with clockspeeds, we should see around a 10-12% real world performance gain.
Starting as always with Crysis, what was already an incredible lead for the 7970GE becomes increasingly absurd. The 7970GE OC sees a further 8% performance improvement here, pushing it past 60fps at 1920 and past 40fps at 2560. Against the stock GTX 680 it’s now leading by 35% on average framerates.
Minimum framerates on the other hand haven’t changed by nearly as much. Given what we know about PT Boost and Crysis’s love of memory bandwidth, it’s reasonable to assume we’re being held back by memory bandwidth limits here.
Moving on to Metro, the 7970GE once again gains 8-9% due to our overclock. The earlier 56W jump in power consumption at the wall makes it an expensive gain, but as it stands this is by far the fastest we’ve seen a single-GPU card perform at Metro.
With Batman we once more see gains of around 9% from our overclock. Even at 2560 our framerates are now in excess of 70fps.
With Portal 2 being one of the 7970GE’s biggest defecits relative to the GTX 680, a solid overclock can help to close the gap but it’s not enough to eliminate it. Still, it’s enough to push the average framerate over 60fps at 2560 with SSAA. The overall scaling from the overclock also looks very good here, with the 7970GE OC picking up a larger than normal 11-12%.
Finally we have AMD’s other notable weak spot, Battlefield 3. Much like with Portal 2 overclocking can’t eliminate the GTX 680’s lead, but it can significantly cut into it. At 2560 and at 1920 with MSAA this is enough to push past 60fps, making for a solid 10% performance gain from overclocking.

They can justify it, the are the amd fanboy. Ever DOLLAR counts when it comes to card pricing, five or ten bucks makes amd the WINNER !!!!!!!! and greatest card value ever for enthusiasts !!!!!!!!!!!But then, moments later, the nearly unavailable and much more expensive montior is all theirs, at their bosom (moments before they harped amd wins in high rez triple screen no matter the data) - now suddenly they have a 1920x1200 IPS or whatever...
Here's why...
1920x1080: " GeForce GTX680 is on average 17.61% more efficient than the Radeon 7970.
Here, the performance difference in favor of the GTX680 are even greater "
1920x1200: " GeForce GTX680 is on average 10.14% more efficient than the Radeon 7970.
At slightly higher resolution appears to have slightly worse performance of the new card (compared to 1920x1080). "
That's an over 7% performance difference overall... nVidia still kicks amd's lousy second placer, but it's not SO embarrassing at 17%+....
See, now they all love 1920x1200 and will DEMAND as hyper-harpies that anand keep the monitor rez as is...
In the end it will just be anand "listening" to it's fan base.... R O F L
Dude, they COULD just run their 1920x1200 in 1920x1080 for the benches - it's not hard at all - but you know... amd doesn't look better than crappy as heck then..

I couldn't care less which it is as long as the image is good. I do think you're downplaying the framerate advantage of 1080p over 1200p though as we're talking an extra 11% screen area going from one to the other.1200p used to be far more common and Apple are one of the manufacturers keeping it alive (along with 4:3 ratios).

Real good dudes use 1920*1200silverblue - Monday, June 25, 2012 - link
Nah. With a card like these, I'd rather use 2560xwhatever. :PZok - Friday, June 22, 2012 - link
Maybe I missed it in the article, but does the lack of hardware changes mean that existing 7970s can be "upgraded" by being flashed with a 7970GE BIOS (so long as they can hit the clock speeds)?haukionkannel - Friday, June 22, 2012 - link
No it can not be upgraded... So what else has been changed?http://www.tomshardware.com/reviews/radeon-hd-7970...
Zok - Friday, June 22, 2012 - link
Well that's disappointing. Wonder if there are hardware changes or a workaround is possible.haukionkannel - Friday, June 22, 2012 - link
You said that you may use some extra setting for Scyrim... How about using some popular extra large texturemap upgrade? It would be more punishing to use those larger texturemaps, and In Scyrim, like Oblivion before, those texturemaps are guitep popular among users of more poverfull graphic cards!milkod2001 - Friday, June 22, 2012 - link
7950/70 games+computing /trade off :noise+power less efficient670/80 games/trade off:weak in computing
the only card I find as a good choice would be 670 but it needs to get to 300-350 price level
