okidoki back with some more info

this would explain the chart and the numbers might be very real, but enabling AF kills performance of the HD 4890/4870X2 (and possibly HD 5870)

The show continues with 3DMark Vantage results:

Tested on a Core i7 965 system with 6GB memory.

and then a comparo: Radeon HD 5870 vs Geforce GTX 295 and Radeon HD 5850 vs GTX 285

Vantage numbers seem correct

same as the Czech gamer site; the HAWX results are also correct, without AF ATI does quite well there; but enable it and you lose 50% performance.
Looking forward to the HD 5870, fastest GPU and an impressive speed bump over the GTX 285, it even matches the 295 in some games/settings!
The HD 5850 will be priced $100 cheaper than GTX 285 but deliver same performance... ouch

Biased baby... but the cards look overal impressive, let the price wars begin...

Ouch... so used to be AA killed ATI's performance... now it is AF?? Almost everyone uses 16AF, I wonder what is going on with this. Perhaps an early driver issue??

Edit: I spoke to soon, AF doesn't seem to be killing performance in that large performance chart, sounds more like a single game issue now.

yes, in most games 4xAF comes for free with recent VGA cards, and small performance drop for 8/16xAF, only in HAWX it seems to be an issue for ATI:)

one last chart, HD 5870 CF vs GTX 295 SLI
