AMD Radeon HD 7970 GHz Edition Review: Battling For The Performance Crown

Synthetics
Because the 7970GE uses the same architecture – and indeed same chip as the 7970 – there’s not much to report here with synthetic performance, but we’ll quickly run through the numbers.
Starting with 3DMark Pixel and Texel Fill, the 7970GE improves on the 7970 around as expected. Pixel fill is a bit low at only 4.5% though, which is unexpected since the 7970GE got a big boost in both its core clock and its memory clock.
Next up is tessellation. While at normal tessellation levels we’re CPU or otherwise throughput limited, at maximum tessellation levels the 7970GE further improves upon the 7970 by 13%, which means we’re likely seeing the full impact of PT Boost in action here. However at this performance level we’re also approaching the same throughput limits we saw with normal tessellation, which means that we either need a better test or GPUs are reaching the point where they have more than enough tessellation performance for future games.
Finally we have Unigine’s Heaven. The GTX 600 series has always done well here, and while the 7970GE improves on the 7970, the GTX 680 is still well ahead for what it’s worth.

There will be custom designs with nice quiet coolers flooding the market in no time..raghu78 - Friday, June 22, 2012 - link
http://www.tomshardware.com/reviews/radeon-hd-7970..."There’s a silver lining on this one, though. Ahead of this review, I let AMD know about our acoustic concerns and the company claims that most partner boards will employ third-party cooling, not its reference configuration."
So noise is not an issue at all. Cards like sapphire with dual x , gigabyte with windforce, powercolor with PCS+ have good cooler designs. Power will be more. But the Radeon HD 7970 Ghz edition frankly more than makes up for that with its performance at 1600p and multi monitor setups.
If you are on a 1080p monitor and want perf/watt , price perf and a cooler setup go for custom GTX 670. For the rest who have 1600p or multi monitor frankly there is only one option - a custom Radeon HD 7970 card or a custom Radeon HD 7970 Ghz edition.

Hogwash, the GTX 680's and GTX 670's are still SMOOTHER, and more enjoyable at high rez and multi monitor.Check the hundreds of reviews.

AMD should have released a balanced 7970 in the first place, somewhere halfway in performance between the 7970 and GE. Now they have an overconservative card and an powerhungry monsterReikon - Friday, June 22, 2012 - link
On page 3:"For AMD the 7970GE will be launching with the Catalyst 10.7 beta, while NVIDIA has released the 304.48 betas for the entire lineup."
I think you mean 12.7

Whoops. Thanks.fausto412 - Friday, June 22, 2012 - link
Will these new Power Tune and overclocking advancements trickle down 6900 series cards to unleash more performance safely?What would prevent AMD from affective the 6990 with these new advancements?

These features would require a new BIOS. As far as I'm aware, AMD does not support flashing their cards with new BIOS. Anyway, there's nothing there that you can't acheive via normal overclocking anyway (asides from the slightly better chip binning).silverblue - Friday, June 22, 2012 - link

Did you try reaching AMD to comment on the rather low performance ceiling on Skyrim? looks as if their drivers are way more CPU hungry than Nvidia's and that's why they are getting capped at a lower rate.Maybe that's what usually hinders performance in other CPU limited titles like WoW?
