SLI vs Crossfire scaling

post #1 of 4
Thread Starter 
I just noticed this.

In COD4 (Yes I know not much of a test) that the HD48xx are scaling much better than the GTX 2xx with multi GPU setups

For example:

GTX 280
@1280x1024
-Single = 83fps
-Sli = 125fps
50.6% improvement ok

@2560x1600
-Single = 43fps
-Sli = 77fps
79.1% improvement nice

HD4850
@1280x1024
-Single = 72fps
-XFire = 143fps
98% improvement very nice

@2560x1600
-Single = 32fps
-XFire = 67fps
109.3% improvement WOW!


So
2 GTXs = only 1.5 GTX

But
2 48s = 2 48s Now thats bang for your buck!

actually the gtx also scale nicely,but you need a quad running at 4Ghz to harness their power,the tri sli review at guru3d showed that these card do scale nicely if you have a beast of a cpu.

One thing is for sure, both companies seem to have their multi-GPU scaling down much better then they used to.
