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.

"All the same AMD has also boosted their memory clocks from 5.5GHz to 6GHz, which will give the card 9% more memory bandwidth with it needs it."=>
"when it needs it"

RyanAs you mentioned Dirt Showdown will take the place of Dirt 3 in your test suite I would like to make a suggestion that a few more games be changed. Max Payne 3 and Alan Wake are good changes. Maybe Crysis Warhead could be replaced by Alan Wake and Portal 2 by Max Payne 3. Another very demanding game which could find a place is Witcher 2 Enhanced edition. Focusing on games released in the last 12 months in your test suite helps prospective buyers / gamers decide based on performance on recent titles which they will most probably be playing.

You are showing the OCed version of the 7970e in comparison to the stock GTX680.For fairness the stock GTX680 should be Overclocked also.

There's nothing fair or unfair about overclocking. Why do people bring this up every time there's one of these articles...CeriseCogburn - Saturday, June 23, 2012 - link
Good to hear it this time, as all the prior moaning has been amd fans wailing that the 680 core is already overclocked out of the box !L M H O
I just want to see the 470, 480, 570, and 580 at the equivalent radeon clocks for those series, and see amd get SPANKED even more in those series.... to be fair, of course....
Yes, thanks so much for saying "you guys always say it" - no - it's not "you guys" - it's the amd fan boys !
This time they didn't moan and complain about fairness, because amd got beat anyway, and they wouldn't if it won, which it did not, I must point out, feeling the overwhelming need to state, again, and again.
This sums it up well: AMD loses, as usual

They're also comparing the OCed version of the 7970e to the stock 7970e. That seems unfair to me. To be fair, you should only compare the OCed 7970e to itself, the OCed 7970e.Arbie - Friday, June 22, 2012 - link
It's probably too late now, but there were at least three more places where you could have used "performance crown" in the opening paragraphs.

Amd LIED, with their false advertising about this card - their hot loud slow housefire...Amd is an evil corporate monster who lies to the little children they sell their products to (and to soccer Mommies who actually pay the card price to keep the lies going - granted they pay less than Abu Dhabi oil sheiks)

Another successful paperlaunchI'm not sure why they could not wait until they had actual product available.
