Total War: Shogun 2
One of our goals with this iteration of our benchmark suite was to throw in some additional non-FPS games, so we’re broadening our horizons a bit by adding in Total War: Shogun 2. Shogun 2 is the latest installment of the long-running Total War series of turn based strategy games, and alongside Civilization V is notable for just how many units it can put on a screen at once. As it also turns out, it’s the single most punishing game in our benchmark suite.
When deciding on what settings to use with Shogun, it required a bit more creativity on our part. 2560 is a true moonshot; everything is turned on, and it takes a minimum of 1.5GB of VRAM to run the game at this resolution. Accordingly performance is rather dismal, though as this is a TBS 30fps isn’t quite as critical as it is in other games. In any case the 7970 comes the closest to hitting 30fps, coming in just shy at 28.2fps, which is 29% ahead of the GTX 580 and 48% ahead of the 6970.
Meanwhile for 1920 we turned Shogun’s settings down to Very High, and yet we still had to disable MSAA to make it work with 1GB cards (did we mention that Shogun loves VRAM?). At these lower settings performance rockets up, and at the same time so does the 7970’s lead over the GTX 580. Here it’s 36% ahead of the GTX 580, which will be the greatest lead among all of our gaming benchmarks. As for the 7970 compared to the 6970, it’s still 48% of the 6970 showing us just how similar these video cards are at times.
Finally at 1680 the overall performance goes up yet again, but the 7970’s lead remains. It’s ahead of the GTX 580 by 30%, and 48% ahead of the 6970.

Hi Ryan , All these older GPUs ie (5870 ,gtx570 ,580 ,6950 were rerun on the new hardware testbed ? If so GJ lotsa work there.FragKrag - Thursday, December 22, 2011 - link
The numbers would be worthless if he didn'tAnand Lal Shimpi - Thursday, December 22, 2011 - link
Yep they're all on the new testbed, Ryan had an insane week.Take care,

How many monitors on the market today are available at this resolution? Instead of saying the 7970 doesn't quite make 60 fps at a resolution maybe 1% of gamers are using, why not test at 1920x1080 which is available to everyone, on the cheap, and is the same resolution we all use on our TV's?I understand the desire (need?) to push these cards, but I think it would be better to give us results the vast majority of us can relate to.

The difference between 1920 x 1200 vs 1920 x 1080 isn't all that big (2304000 pixels vs. 2073600 pixels, about an 11% increase). You should be able to conclude 19x10 performance from looking at the 19x12 numbers for the most part.I don't believe 19x12 is pushing these cards significantly more than 19x10 would, the resolution is simply a remnant of many PC displays originally preferring it over 19x10.
Take care,
Anand

Oh, and my laptop is 1920x1200 too, Dell Precision M4400.My old laptop is 1920x1200 too, Dell Latitude D800..

Heh, I too have 3 Dell U2410 and one Dell 2710. I REALLY want a Dell 30" now. My GTX 580 seems to be able to handle any of these monitors tho Crysis High-Def does make my 580 whine on my 27 inch screen!mczak - Thursday, December 22, 2011 - link
The text for that test is not really meaningful. Efficiency of ROPs has almost nothing to do at all with this test, this is (and has always been) a pure memory bandwidth test (with very few exceptions such as the ill-designed HD5830 which somehow couldn't use all its theoretical bandwidth).If you look at the numbers, you can see that very well actually, you can pretty much calculate the result if you know the memory bandwidth :-). 50% more memory bandwidth than HD6970? Yep, almost exactly 50% more performance in this test just as expected.

That's actually not a bad thing in this case. AMD didn't go beyond 32 ROPs because they didn't need to - what they needed was more bandwidth to feed the ROPs they already had.
