Civilization V
Our final game, Civilization 5, gives us an interesting look at things that other RTSes cannot match, with a much weaker focus on shading in the game world, and a much greater focus on creating the geometry needed to bring such a world to life. In doing so it uses a slew of DirectX 11 technologies, including tessellation for said geometry, driver command lists for reducing CPU overhead, and compute shaders for on-the-fly texture decompression.
Thanks to AMD’s radically improved compute shader performance, the 7700 series fares extremely well here. Instead of stuggling to keep up with the 6850, the 7770 is well in the lead even against the 6870. Throw in XFX’s factory overclock and now a 7700 card is leading even the GTX 560 on a game NVIDIA was handily winning 2 months ago. Even the 7750 greatly benefits here, tying with the 6850 instead of the 5770 as it normally does.
It’s a shame for AMD that more games aren’t like Civ V, for if they were the 7700 series would look quite a lot better.

I thought the 7770 would outperform the 6850 at least. Great review.sigmatau - Wednesday, February 15, 2012 - link
For AMD cards, you look at the second number to indicate performance. An 8 series card like in the 6850 usualy performs as well or slightly better than a next generation 7 series card like the 7770.The 3rd number also indicates performance, but not nearly as much as the second number.

er, not really. A 58xx is faster than a 68xx.sigmatau - Wednesday, February 15, 2012 - link
The 68xx series introduced an anomaly in the formula. But generaly what I stated is true.CeriseCogburn - Saturday, March 10, 2012 - link
The anomaly here is the NVIDIA Gtx460 SMOKES the 7770 on everything, in every test, and costs 33% less.I see the crazed fan base cannot bring themselves to say it.
I'll say it - 19 pages unsaid, over a long time.
THE NVIDIA GTX460 SMOKES THIS CARD RO DEATH, AND THERE'S MORE OF THOSE ON NEWEGG FOR LESS MONEY THAN THE 7770.

My word you are tiresome.nissangtr786 - Thursday, July 5, 2012 - link
Using your logic a gtx 580 smoke the gtx 460.The reason why 7770 costs a bit is because its new technology, power consumption goes down quite a bit. Compare the card to same power consumption of new generation card maybe a 7870 and the 7870 will smoke the gtx 460.
perferformance per watt 7770m smokes the gtx 460.

you seriously need to stop posting. everything you post comes off as rabid nvidia fanatic, because you evidently are one, and you seem to camp outside these benchmarks to say the same thing everytime!! "this thing SMOKES~~~~!! the 7770!!! thats all i look at are the frame rates!!! i dont take anything else into consideration cause im an nvidia superfan"Beararam1 - Thursday, February 16, 2012 - link
Really? I thought the 6870>5850. No?CeriseCogburn - Saturday, March 10, 2012 - link
This 7k series needs some www.verdetrol.com--
LOL - How low can you go amd ?
Seems like more firings and cullings are in the works - or perhaps they already dragged the cat in and are now stuck with perverts.
