If you've ever wondered about multi-GPU performance and whether CrossFireX or SLI would scale better across multiple cards, OCC has put together a Crossfire vs SLI Performance Comparison. You can check it out here - http://www.overclock...ossfire_vs_sli/



If you enjoy this, perhaps you wouldn't mind to take a moment and Digg the article. :) ~d3bruts1d

Physx enabled? Blah.

It'd be interesting to see an average scaling chart with percentage increases over the single GPU versions of whatever GPUs were tested.

I noticed that the two HD4850 X2s in CrossFire owned two HD4870 X2s in CrossFire (Crysis), how is that possible rly? :o
But the review is very very helpful and i like it rly much. Id say it's the most helpful review about multi-gpus in the whole wide world in like last 3 years...
Then again... it is OCC and OCC is the best... makes sense imo. :D

I'm guessing the results got swapped by accident or something based on the other results.

I will double check just to make sure

Your point? There are always anomalies, the differences here don't look that great...It could just be a couple of isolated cases where the cards scale better.

That's cool. It wouldn't be the first time we've seen odd results with no explanation. Computers have a habit of doing things like that to vex us. :lol:

Ya Crossfire is funny that way. Everyonce in a while you get something that makes you retest over and over again because you can't believe it :lol:
