First of all, if the focus on cypress and fermi is about DirectX11, then it is clear that Fermi wins by far.
480 vs 5870 on unigine
Forget about the FPS, just look at the scene, which card produce a smoother scene through the branch?
Of course the "6 month late" is being used over and over again, but then are you comparing 480 with the 5870 at launch? Both have limited supplies at launch. Now I don't look back, I look at what we have now. There are lots of 5870 around, but not 480, which is a true problem in terms of purchase. Other than that, I don't see why that "6 month late" plays any roles.
No one denies the fact that 480 uses more electricity. Because of that, it produces more heat. Because of that, it produces more noise. Breaking this down into 3 separate points is not a fair comparison. Now 480 requires more electricity, about 33% more than 5870 but produce almost 100% better on unigine branching. Is this not efficient?
Now back to Dx9/10 games, both cards play toe to toe. Now the thing that eats up FPS is AA, and both vendors attack it differently. The new architecture should be able to compute AA using a new method, which is not effective on older generations. Until that is out, they are still using the old method, and therefore, not completely utilizing the card. Yes, I really don't know if there will be a new driver that increases the performance, but is it really so gay to say that there is a high possibility?
As of now, with the existing driver, it ties with 5870 on Dx9 and Dx10 games, but beat 5870 under Dx11 branching. Is it not logical for engineers to focus its performance on Dx11 before Dx9/10 as Dx11 is the "big thing" now?
You may say that 480 don't have a lead on Dx11 games, but you should also know that those so called Dx11 games are really Dx10 plus a few Dx11 support that doesn't impact the game. In other words, you can treat them as Dx10.
Again, I am not saying that 5870 is garbage and people should throw it away and grab 480. In fact, they are both good cards. If you already got a 5870 card, gratz on the new card. I just hope that people who got the new Fermi card can have the same blessing instead of telling them that they have got a old ineffective hot junk, or the thing that Mrk6 described.
