Batman: Arkham City
Batman: Arkham City is loosely based on Unreal Engine 3, while the DirectX 11 functionality was apparently developed in-house. With the addition of these features Batman is far more a GPU demanding game than its predecessor was, particularly with tessellation cranked up to high.
Previously both the 7970 and GTX 680 were tied here at 2560. With both AMD and NVIDIA improving their performance here however, things have finally begun to separate. The GTX 680 now has a small-but-measurable lead over the 7970, but it’s not enough to hold off the 7970GE. As a result the 7970GE enjoys a 5% performance lead at 2560. Strangely however it falls behind by a significant margin at 5760, which is not what we would have expected.
As a side note, it's worth mentioning that Batman is one of the titles with PhysX support that can actually make a difference in how the game looks. While performance with our non-PhysX settings may be close, there's something to be said for the PhysX effects here. That's an NVIDIA exclusive, and if it's something you want you'll have to go with an NVIDIA GPU.

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.
