The slides below have been around for a while, and I initially hesitated in posting due to questions regarding their validity. It seems, however, that they may indeed be relatively accurate.
|More and more information about the soon to be launched Radeon HD 4800 series is surfacing as we approach the launch date, which is still to be determined. The latest to hit the web are a couple of slide that show the performance of Radeon HD 4870 and 4850 in comparison to their respective nemesis, GeForce 9800GTX and 8800GT/9800GT. Of course, AMD comes out on top in all benchmarks, but they do it with a higher than expected margin. Radeon HD 4870 whips 9800GTX by a 40% margin, while 4850 outpaces 8800GT with the same number. The tests ran at 1900x1200 with 8x anisotropic filtering. It really does seem like the AF problems are fixed. Do remember this is AMD's in-house testing and the tests may of course be cherry-picked.

Kudos to AMD for not screwing with the y-axis, unlike some other...
