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.

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.
