ATI IS STAKING its high-end reputation on its upcoming 3870 X2 card, which has two R670 chips on a single board. Details have been scarce, but not only has one turned up in a system at CES, but it's been benchmarked too.
The card is absolutely huge-mongous, with two GPUs, two sets of memory, two power connectors and a bridging chip sat between them - not to mention the Crossfire connector sat on the top.
There's 1GB of memory on board, and the GPUs are currently running at 770/2250MHz.
The folks at Hot Hardware have pics of the card from the show floor here, whilst the stripped naked pics and benchmarks are over here at OC Workbench. Tasty. µ
even PCI-E 1.0 spec would most lieky not get saturated in 16x/8x bridge mode

PCI-E 2.0 has 2x more bandwith then 1.0 spec so 2.0 is getting 16x type of speeds per chip in that 3870 2x mode
Very nice scoring for x2 but i'm still sad... they only made a pciex bridge that is capable of 8x speed, sure... it's pciex 2.0...but it's 8x.does it have enough bandwith througput to deliver the power it really have? Dunno
ATI where? You guys means AMD?
