Total War: Shogun 2
Total War: 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 (on higher end hardware at least).
Similar to what AMD did with improving their DiRT 3 performance, NVIDIA has similarly improved their Shogun 2 performance. NVIDIA was previously bitten by a major performance regression introduced in a March update for Shogun 2, which significantly reduced performance at 2560 with our Ultra settings. With NVIDIA having fixed that regression through a driver update, their performance has now been restored.
Consequently this is the first game where the 7970GE can’t power ahead of the GTX 680 at 2560. The 7970GE is just fast enough to break past 30fps, but compared to the GTX 680 the latter has a 12% performance lead here, which is a big deal for NVIDIA since performance is low across the board here.
Like we saw with the GTX 670 versus the 7970 and the GTX 570 versus the 6970, performance patterns are quickly devolving to the point where any performance leads are extremely inconsistent and strongly depend on the game in question. Or in other words, we’re going to see a lot of back-and-forth movement with the 7970GE winning with some games and the GTX 680 winning with others. For better or worse there won’t be a single clear winner across every game.

A whole new card launch and yet another pair of similarly named but differently performing products because they changed a few numbers that anyone can in several free, easily available programs.I suppose they can do this because you can actually buy their products though, unlike the 6XX series.

Yeah, tough to find 6xx products indeed. There is something called the 'internet' you could check out. Your buddy who posted for you might be able to help you out. ;)Pantsu - Friday, June 22, 2012 - link
I doubt any AIB will actually release GE cards with reference cooling. Most likely they will be custom cooled, so the loudness of the reference card is a bit of a moot point.It's good to see some decent driver improvements from AMD. I'm still quite happy about 7970 performance at 5760x1080, and it's enough for most games when OC'd. It would be interesting to see though, whether the GE has improved the max OC. Most likely it's no better though, and you'll be better off buying an old custom 7970 for a good price and OC'ing it to the same levels as the GE.

The GE chips are better binned parts, one would assume that they have a bit more room for higher clocks than the normal 7970 parts. Certainly the average overclock will be higher.CeriseCogburn - Saturday, June 23, 2012 - link
So we can deduce that the prior 7970 overclocks were sucking down an even larger amount of enormous electrical power as those chips are of lower bin.I guess we need an overclocked power suction chart with an extended table for the amd housefire 7970.
Any savings on card price or a few frames at a resolution near no one owns will be gobbled up by your electric bill every month for years - save 1 watt or 9 watts at extended idle, but when you game it's 100+ watts and beyond with the overclocked 7970 - maybe they should be $300 with 3 games.

Well, it works both ways. You won't always be gaming, in addition there's all that compute hardware that, if properly harnessed, would save you money over competing solutions because you'd get the job done quicker. It used to be pointless to consider using anything for compute that wasn't a Quadro, Tesla or even FirePro, however those days are coming to an end.Having a 7970 will make sense for compute if that's your bag (there's a reason for the die size plus the extra memory and bus width), but this time, NVIDIA enjoys a performance/watt advantage which might go unchallenged for a while. Unless, of course, that extra hardware on the 7970 is properly leveraged; future games, perhaps?

So do we think this will encourage nVidia to release a GeForce GK110 based product in the next few months rather than restrict it to Tesla?PsiAmp - Friday, June 22, 2012 - link
Nvidia isn't holding GK110 in its sleeve waiting for something. It is unfinished in the first place and there's no manufacturing capacity to produce such a large chip. Nvidia still struggles to fix GK104 design to have good yields. GK110 would be impossible to produce in since it is twice bigger and such will have at least 4 times less yield.Server market is not only much more profitable, it is operating on a contract basis. Nvidia will start to produce Tesla K20 in Q4 2012.
IF(?) desktop card based on GK110 will hit the market it won't be sooner than Q1 2013. And it is not something that you can change really.

"Of course this isn’t the first time we’ve had a hot & loud card on our hands – historically it happens to NVIDIA a lot – but when NVIDIA gets hot & loud they bring the performance necessary to match it. Such was the case with the GTX 480, a notably loud card that also had a 15% performance advantage on AMD’s flagship. AMD has no such performance advantage here, and that makes the 7970GE’s power consumption and noise much harder to justify even with a “performance at any cost” philosophy."Very true, however the power consumption and heat difference between the 5870 and the 480 was definitely more pronounced.
The 680 is an incredible card, no doubt about it. It may not win in some titles, but it's hardly anywhere near unplayable either. AMD being right there at the very high end is fantastic but unless titles truly make use of GCN's compute ability, the extra power and noise are going to be hard to swallow. Still, I'd own either. :P
