The 4850x2 does have 2gb of ram, so it will outperform 2 4850s in xfire at higher res...but then you would just get a 4870x2...

Normally on the 2gpus on a single die they downclock the gpus to below standard clocks as there is only one cooler to cool twice the heat. Two in crossfire would have more raw performance and probably cheaper you probably would only need 2gb of graphics memory if your running at higher then 1900x1200 providing you have sufficient system RAM

The 4850X2 has two RV770 chips at the standard core speed of 625mhz just like a single 4850.

Two in xfire would be the same thing. And the 4850's reference design uses a single slot cooler while the 4850X2's is a large dual slot...it should cool extremely well.

Basically an overclocked 4850X2 will match a 4870X2...just gotta get the core clock up to 750mhz
which might be hard to do.

clocking it to 750 alone will not do it

do you forget quad pumped gddr5 memory.. HUGE bandwidth difference

The 4850X2's memory runs at a higher clock speed (186mhz higher to be exact) so that will make up part of the difference, and it is 512bit so its not like its slow.

it would not be cooling twice the heat, twice the heat would be say 60 degrees compared to 120 degrees, you cannot just plus the radiance heat together. let me put it this way, if u have 2 jugs of water at 30 degrees, combine them together and its still 30 degrees water, and takes less energy to cool down the a jug of 60 degrees water.

Last time I checked a jug of water isn't a self heating entity so isn't up for comparison as gpu's produce heat. Put 2 on a single board and you double the number of heat producing elements and thus the temperature would be doubled if the same cooler was used as the single gpu.
