AMD's Radeon HD 4870 X2 - Testing the Multi-GPU Waters

Race Driver GRID Performance Scaling
Memory is king in the game at 2560x1600. Our 1GB cards handle the stress the best, and lower framebuffer sizes mean worse performance (especially during loading screens which ran incredibly slow). Our 512MB 4870 cards tanked in CrossFire at 2560x1600, while the 1GB per GPU 4870 X2 delivered wonderful performance. At all other resolutions, the single 4870 performed really well, but we will be interested in seeing if the 1GB version bumps performance up another notch here.
This game, like Age of Conan, runs incredibly well on AMD hardware. Both CrossFire and SLI scale very well, with 4-way CrossFire once again delivering a flat line of performance across all resolutions.

That kind of message was I hoping for to get from review... a kind of didn't happen.BRDiger - Tuesday, August 12, 2008 - link
I just wondered if you useed the 8.8 Catalysts... The testing rigs specs would be nice for comparison of the benchies...nubie - Wednesday, August 13, 2008 - link
This is interesting, and thanks for the hints about a 1GB model, but guru3d ran an article two weeks ago on a 2GB 4850, so I believe that is trumped.I too was hoping for more enthusiasm, the 9800GTX is $200 and the just released GTX 260 is under $300?? Stop the presses nVidia is no longer on top!!
AMD has wrested back the performance crown with a vengeance, and their mainstream products are totally playable in recent games.
Meanwhile nVidia is trying to plug every price point with the 8800GS and 9600GSO and the 9600GT, not to mention the 9800GTX+, this is freaking ridiculous.
You need to paint a more realistic picture, this is one of the rare times that mainstream games can be played for $170 while decimating the competition's products that cost $250, and the high end is owned by the same company with a working Dual chip card with the performance crown, and being a more efficient electricity user than the competition.
If nVidia comes out with a GTX 260 x2 or a GTX 280 x2 I am going to look very carefully to see how glowing THAT review is.
I want SLi and Crossfire to die. There is no reason to only allow 2 displays (or worse just one) on a multi-output machine. Worse still a machine with 2x PCI-E 16x slots (even in dual 8x mode) should be allowed to run any hardware that fits in them.
This software hampering of a completely standard PCI-E interface is stupid and childish, they should just drop it.
