Dueling Drivers, A PR Do-Over, & The Test
Coinciding with the launch of the 7970GE, both AMD and NVIDIA have released new drivers this week. For AMD the 7970GE will be launching with the Catalyst 12.7 beta, while NVIDIA has released the 304.48 betas for the entire lineup. For both AMD and NVIDIA these are major performance drivers, with both groups seeing significant performance in a handful of games.
We’ll take a look at the full performance spectrum starting with our regular benchmarks on the next page, but first we wanted to quickly break out the performance impact of the driver changes for both the 7970 and the GTX 680 at 2560x1600.
The biggest gains for AMD and NVIDIA are seen in DiRT 3 and Shogun 2 respectively. For reasons we’re not fully sure of, AMD has managed to significantly improve their performance on DiRT 3 and turn the tables on what was previously a game favoring NVIDIA. At the same time however NVIDIA has finally fixed the Kepler performance bug that was introduced in the March update for Shogun 2, restoring performance to where it was before the update and pushing NVIDIA ahead of AMD once more.
Meanwhile AMD sees lesser gains in Batman, BF3, and Skyrim, while NVIDIA also gains on Batman but that’s about it. Altogether AMD’s latest driver update has pushed their average performance ahead slightly more than NVIDIA’s, which for the 7970 versus the GTX 680 means that the GTX 680 now leads by about 9% instead of 10%. It’s not nearly enough to change any recommendations, but the fact that AMD and NVIDIA have swapped leads in certain games is a reminder of how important drivers can be and how volatile performance leads are.
A PR Do-Over
Because the 7970GE is functionally identical to the 7970 save its higher clocks and PT Boost, we’re opting to use our limited time to focus solely on performance. With that said it was interesting to see that AMD is very much treating the 7970GE launch as a do-over for the 7900 series. In their press presentation they spent a fair bit of time focusing on various aspects of the 7900 series and GCN we’re already familiar with, such as compute performance, their Leo technology demo, and of course GCN.
None of this has any direct relevance to the performance of the 7970GE, but we thought it was worth mentioning since it gives a bit more insight into how AMD is approaching things. This is all we’re going to say on the matter, but we have reproduced a few of the press slides below for any of you that are interested.

LOLor
AMD sucks, but in a good way

In the normal clock tests you test 5760x1200 which is a very good thing. Could you not do the same resolution with your overclock tests as well? I would really like to see how triple monitor performance is overclocked.Another thing I was wondering, does running triple monitor at 5760x1200 increase power usage of the card or make it run hotter?

1) Obviously it's a bit too late for that in this article, but we can certainly look into doing that for future articles.2) Generally speaking, no. Unless a card is already operating well under its PT limit (in which case the game is likely CPU-bound), increasing the resolution doesn't significantly shift the power consumption. The actual display controllers are effectively "free" at these power levels.

Not retaking back performance crown?cmdrdredd - Friday, June 22, 2012 - link
Nope because it doesn't win every single benchmark. Just because it wins one resolution doesn't equate to being the fastest one.CeriseCogburn - Tuesday, June 26, 2012 - link
If any of these people had been paying any attention at all in between articles ( meaning checking on the net) they would already know it takes about 1250 on the 7970 core to equal the 680oc.1000 doesn't do it. 1050 nope. 1150 nay.
Hexus already proved same core speed results in the 7970 behind. That's already been linked in replies.. so here it is because the amd fans will descend calling names and declaring liar (though they likely saw it before and just can't for the fanboy of themremember, as most brains use the delete key a lot)

My regular stock 7970 overclocks higher than this Ghz Edition, and does it on lower voltages. At least this makes the prices drop on regular 7970's.owendingding - Friday, June 22, 2012 - link
I think we can find a 7970ghz edition bios and put it on a regular 7970 and achieve the same performance. I also assume that you have a non reference 7979, like mine a gigabyte wind force you can get a lower temperature and 680 like performance. I just hope that bios is universal.CeriseCogburn - Tuesday, June 26, 2012 - link
Someone already posted Tom's shows it is NOT universal and cannot just be flashed to any 7970.NOPE. Amd locks you out, because they are evil.
