Portal 2
Portal 2 continues the long and proud tradition of Valve’s in-house Source engine. While Source continues to be a DX9 engine, Valve has continued to upgrade it over the years to improve its quality, and combined with their choice of style you’d have a hard time telling it’s over 7 years old at this point. Consequently Portal 2’s performance does get rather high on high-end cards, but we have ways of fixing that…
On the positive side, Portal 2 is easy enough to run that the 7770 easily clears 60fps at 1920, even with 4x MSAA. On the down side, the 6800 series does the same thing only better. Regardless of the resolution this is one of the worst games for the 7700 series, as even the XFX BESDD can’t crack the 6850. The 7750 somehow fares even worse, falling just behind the 5750, never mind the 5770. While this is largely academic thanks to the high framerates, it would appear we’ve found a general weakness in the 7700 series.

Kepler really, really needs to come out soon, and I'm saying this as an AMD fan.Malih - Wednesday, February 15, 2012 - link
Exactly, I'm a fan of AMD myself, and I can't wait for Kepler, AMD needs a kick in the (you know what)DimeDeviL - Wednesday, February 15, 2012 - link

uhhh really? same card performs better hehehehetynopik - Wednesday, February 15, 2012 - link

I feel like reviewers were blinded by performance with the 7970/7950 cards. They offer the same lack of competitive pricing as these lower end cards. The 7950 can be compared directly (in price and performance) to the Nvidia GTX 580, a card that was available a year ago.I'm still rocking a pair of 4870s that set me back ~$400 a few years back. To get a substantial performance upgrade, I'd have to spend $450 on a 7950 today. Where is the value in that? Yes, power consumption and features are important but are tertiary to raw performance in almost every user scenario when it comes to gaming.
To say the least, the lack of competitive pricing between nvidia and amd currently smells a little fishy.....it wouldn't be the first time there was price fixing in the graphics card industry.

I'm convinced that the pricing for 4870s in late 2008/early 2009 was the sweet point to buy. Yes, power consumption sucks, but other than that, a card that cost me $160 then, is pretty competitive with a card that costs $120 today. I think we may have just lucked out with the 4870s, and may need to wait until at least Kepler, if not 8XXX to upgrade.chizow - Wednesday, February 15, 2012 - link
Just be careful not to set expectations on the 4870's pricing for 2 reasons:1) 4870 pricing was a mistake imo. AMD will say it was a calculated one in fluff pieces like the RV770 story and it was true in some degree that AMD needed to recover mindshare/marketshare and consumer confidence after the R600 debacle and a weak performing RV670. Still, when you set your single-GPU flagship at $300 and your second SKU at $200, there's not much room to go down on pricing.
2) Late 2008 early 2009 was the height of the recession. Wall Street, Real Estate, Auto Industry, all that. Nvidia and AMD were feeling it too and got involved in a highly publicized price war. That's why you saw "new" high-end performance parts like the 4890 and GTX 275 launching for $230-$250 that occupy the $350+ market today, with cards like the 4870 and GTX 260c216 selling at tremendous value for $150 or less.
Its obvious AMD is doing its best to correct their 4870 price mistake over the last few years, but with the overall performance of Southern Islands stack, the 7-series was the wrong time to do it. They should've just stuck to their old pricing scheme or at worst, matched Nvidia's pricing ($500, $380) with their Tahiti parts. Then you might see the rest of the stack priced reasonably.

Yeah, at this point of the business cycle, it sucks to have to buy anything. Everything is expensive due to all the capacity cuts.Recessions are good (for buying things, cars, houses, whatever). Btw: Housing is an anomaly due to efforts to stop/slow the process.

Recessions are good for the rich... not so good for everyone else.
