Crysis: Warhead
Kicking things off as always is Crysis: Warhead. It’s no longer the toughest game in our benchmark suite, but it’s still a technically complex game that has proven to be a very consistent benchmark. Thus even four years since the release of the original Crysis, “but can it run Crysis?” is still an important question, and the answer continues to be “no.” While we’re closer than ever, full Enthusiast settings at a 60fps is still beyond the grasp of a single-GPU card.
With AMD’s GCN architecture, Crysis is finally losing some of its predictive power, but it’s still a good indicator of overall performance. And the indicators aren’t very good.
From a price/performance perspective the 7700 needs to beat at least the 6850 on the AMD side and at least the GTX 560 on the NVIDIA side in order to ensure a clear-cut victory. Unfortunately it’s falling well short of that, underperforming the 6850 by 20% never mind the GTX 560. On paper the 7770 is outgunned on everything from texture performance to ROP performance to shader performance, so take your pick on what’s holding back Crysis performance, but the end result is that it’s well behind its previous-generation peers. In fact it’s closer to the 2.5 year old 5770 than it is the 6850.
As for the 7750, things are a bit better. In spite of its massive texture and shader deficit compared to the 7770, it’s only behind by 15%, offering some strong support that the actual performance difference between the two cards won’t be nearly as big as it is on paper. That said, on a price/performance basis it should be able to beat the 5770, and it isn’t quite there. But as the only card here that’s sub -75W, it has other favorable attributes.
Elsewhere XFX’s R7770 BESDD shows us that 7770 performance scales well with clockspeeds, with a 12% core overclock netting 11% better performance. This is a good sign for overclockers, but for factory overclocked cards it’s a mixed bag, as the higher price these cards fetch only puts them more in competition with the 6870.
The story of minimum framerates is much the same. The 7700 series continues to underperform its last-generation competition by quite a bit, and unfortunately we’re still several frames per second away from being able to sustain 30fps+ in Crysis at 1680.

For the cost of one game you could just get the nvidia 560. In fact you could of gotten it a long time ago and still be way ahead.beginner99 - Wednesday, February 15, 2012 - link
Well seeing this makes me feel a little less bad on how much a paid for my 5850 1.75 years ago. Absolutely 0 reason to upgrade...However now it seems AMD GPU division is starting to blunder too...

I really don't understand what AMD is thinking here. The 7770 is preposterous at this performance/price level, and it boggles the mind that they designed it this way. I'm really stumped here, it's like they're spitting in all of our faces to release a card that has less performance and costs more than a widely available 2 year old part.They must take us for fools. Nothing else could explain this. Technology is supposed to improve as the years go by, not tread water, and certainly not get worse. You see this kind of bs and the revolving door of talent at AMD starts to make more sense. There must be some real pieces of work running that place.
I think it's finally time to join them. Nvidia, here i come.

It's obvious isn't it ? They are a collapsing wreck that have culled with the ax their dwindling workforce as they've sold off assets to leave them with nothing but ip.Now after striking away Bain Capital style at the failing red bottom line - in the deep debt for endless years under the tightwad whining fan base and OCD focused complaint review sites meshing pennies and fps to an insane nuovo art form that should embarrass it's fans rather than fill them with false self esteem and self congratulating "I'm brilliant" mirror apprasials, they must further the save their life goal and actually ask their tenderly coddled and deceived rabid fan base to cough up some survival dollars...
Unfortunately, the years of low price bragging filled with lies albeit effectiveness as an ignorant fool lives in bliss, has come to backfire on them at the worst time possible, the end of the line.
As Mr. Smith said, it was inevitable.
Now amd needs a hero to save it's collapse and absorption into the wider market matrix.

I have a gts250 and I get about the same fps as the 7750. I paid just over 100 bucks (109 IIRC) for it and its almost 3 years old and keeps up with these brand new cards. I cant decide if that's funny or sad.Menoetios - Wednesday, February 15, 2012 - link
While these cards definitely deserve flak for their starting prices, I'm not nearly as disappointed overall as many here seem to be. I have no doubt that their prices will come down in time. Consider that the 7750 is the absolute slowest GCN card. I fully expect to see a tastey sub-$90 price for the 7750s by the time Nvidia gets their 28nm line out. The 28nm process is still extremely supply constrained; it wouldn't make sense to price the cards out any lower to increase sales when there simply aren't any to sell. Whether Kepler trounces GCN or equals it, its introduction will be when the real shift in the price/performance shift occurs, both from competitive pricing as well as the 28nm ramp up.kmmatney - Wednesday, February 15, 2012 - link
Well, I'm glad I was able to pickup an HD6850 for $139 shipped (no rebates). I can see why the 7750 would be great for notebooks, but I don't see much point in this card for the desktop.CknSalad - Wednesday, February 15, 2012 - link
I think it's safe to say that ever since the release of bulldozer, AMD has been hit hard financially. They spent a lot of R&D and probably put all their eggs in one basket in that project. As much as their efforts can be admired, it seems that this has taken so much of AMD R&D money that now they don't have much to offer for even their gpu lineup.I understand that there is little competition and that this is the 'first gen' of 28nm cards, but there should seriously be at least 10-15% performance boost for the whole lineup. Going from 40nm to a 28nm process is a big jump. The 'there is little competition' so these cards are priced this way is still unacceptable. I'm starting to be wary of the 7800 series cards as I'm looking forward to buying a card no more than the low $300 range.
Hopefully Nvidia has something up their sleeves and can give us true 28nm performance we should be seeing. I am in no way an nvidia fanboy as I have had both ati and nvidia cards. The only thing i worry for nvidia's kepler cards is the power consumption. However, if the performance gain more than makes up for the minor increases in power consumption, then it will be more than worth it.

Yes they are price gouging for the next 3 months because they can. Also the 7700 series is complete shit performance wise and will only find its home in the hands of the uninformed and the low power systems built by Dell and HP.Nvidia is the only hope of seeing a good price/performance boost now.

"and at that point, this card at 159$ would make sense."No it wouldn't actually, since with the move to 28nm you should be seeing a performance increase per dollar not the same. The performance of a 6850 should be around $79 this generation, with the $160 cards offering almost 6950/560ti level of performance.
This is what Nvidia will most probably be offering with their next gen parts, and what AMD will have to lower their costs to if they expect anyone outside of the fanboys to but them.
