Louis Pasteur's theory of germs is ridiculous fiction - Pierre Pachet
DAMMIT'S PLANS for an HD 4850 X2 have been confirmed after pictures of a Sapphire implementation of the chippery appeared on a Chinese web site.
The dual-slot card features some heavy-duty cooling and comes with 2GB of GDDR3 memory.
The pictures are here.
The implementation appears to be exclusive to Sapphire - for now. µ
your speed reading to much.
"HD4850 X2 2GB GDDR3的真面目"

looks like 2GB to me
yup. its broken
Yeah, it has to be 2 GB, it can't be 2Gb (256 MB). That's too low.
Why some obscure Chinese forum, when the official pics can be found on the Sapphire web-site.

And in hi-res too! ;)
An ATI X2 card with... GDDR3? Isn't that a bit of a step backwards? Screw that.
You have to remember with DDR4 and 5 in the past Framerates drop completely on those ATI and Nvidia Cards. Going back to DDR3 is Right with my ATI 4850 I can play with the big boys. So 2 smash together running at PCX16 2.0 instead of 8X crossfire . Is pretty darn great, This card will run about 389.00 with rebate.
Check this out.
