Radeon HD 4870, 4850 performance slides

Andreas G · Guest

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. You can find the slides posted by Donanimhaber below.

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

That's impressive if it's true.

once these are released, the enthusiasts will flock to ATI cards...

I wouldn't be too sure about the "cherry picking", Crysis is also included in these tests, and that's a game that's optimized for nVidia's cards.

hmm...
9800 GTX core is about 650 GFLOPs
HD 4870 performance is about 140% of that, sooooo:
HD 4870 is at least 910 Gflops. (but then again that doesn't take memory bandwidth into consideration or driver quality)
