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.

Don't forget, when the 4870 pricing was low, at the end of 2008, BOTH AMD and Nvidia were settling price fixing lawsuits. These companies have cheated before; they'll do it again.Hubb1e - Wednesday, February 15, 2012 - link
"Recessions are good for the rich... not so good for everyone else. "Really? So when the stock market lost 40% of its value and the rich lost 40% of their net worth, that was good for them?
The rich can ride out a recession better than the poor because they don't live paycheck to paycheck, but it sure as hell wasn't good for them.

Maybe we can see 4870's with maximum performance/die size in mind pricing failure because it was performing close to the big die from Nvidia gtx2xx. Or maybe we can see the ''double performance from last gen'' tactic from Nvidia a fail when it means building a super big die with low performance/size ratio just to get that double performance motto... It was all a question of ''goal to attain'' from each company. One goal paid off more than the other that time.From an Nvidia's fanboy perception, the first will be true and the second unthinkable. From an ATI fanboy, the first will make no sense and the second will suit them well. From someone with no choosen side, both can be true.
But these 7770 and 7750 here, makes no sense, such small die with such performance for that price.....

I agree, smells fishy, usually at this point nVidia would lower their card price.The latest price competitive part from AMD is the 6800 series. Probably have to wait for the 8800 series?

I know, I bought a 5850 before the MSRP hike for around $279 + VAT in 2009 and I just checked, it clearly beats a 7770 so a >$159 value today, maybe close to the $200 card being launched in March. The 6xxxx series I thought was just because they had to scrap the 34nm process and deliver essentially a refined 5xxx series, but now they're on 28nm and there's not much bang for the buck for those of us that already have a gaming card from the 4/5xxxx series. I hope this is just a temporary situation until nVidia gets their Kepler out, or I might just sit out another generation...eminus - Wednesday, February 15, 2012 - link
AMD has AMD (Accute Money Deficiency) right now so they need every penny they can gain.Cygni - Wednesday, February 15, 2012 - link
It seriously seems that the 4850/4870 was an incredible purchase. In 2009, you could get a 4850 for $99 dollars. And it STILL holds up to the top range cards.I mean we all know that Nvidia and AMD are playing the profit game 10 times harder than the performance game in this sector, simply because games can't press the limits of the hardware, but it's still impressive.

I bought 4 cards in the 4x lineup..First a 4850 for $170, Second a 4870 for $199 Third a 4870 1G for $229 and lastly a 4830 for 140.. While I live in Canada I don't think prices ever came that low unless you got one helluva good deal.. $99 pricing for the 4850 wasn't the norm even late in its production run.

I got mine real chaep at launch! BestBuy mispriced them. Still, not too much later there were good deals again and I got one for my daughter's desktop. These cards in CF still hold up well for 1920x1200 gaming. I would like to upgrade to better performance and lower power, but AMD is making that hard dollar-wise.Jorgisven - Wednesday, February 15, 2012 - link
Indeed. Best Buy had a 25% off all Visiontek cards the week of the 4850 launch, so I got mine at launch for $150. I then caught an amazing deal on a 4870 a few months later ($129 shipped), sold my 4850 for $140. I basically bought both for a net $140.I've been waiting for a good AMD card, but just haven't seen one. I've been tempted by the 560 Ti or 570, but they're still too expensive for my taste, and don't offer enough of an advantage to spend the cost of a PS3 on upgrading from an already decent GPU.
I'm rather disappointed with Red as of late.
