MojoKid writes "AMD officially launched their new high-end flagship graphics card today and
this one has a pair of graphics processors on a single PCB.
The Radeon HD 3870 X2 was codenamed R680 throughout its development.
Although that codename implies the card is powered by a new GPU, it is not. The
Radeon HD 3870 X2 is instead powered by a pair of RV670 GPUs linked together on
a single PCB by a PCI Express fan-out switch. In essence, the Radeon HD 3870 X2
is "CrossFire on a card" but with a small boost in clock speed for each GPU as
As the benchmarks and testing show, the Radeon HD 3870 X2 is one of the
fastest single cards around right now. NVIDIA is rumored to be readying a dual
GPU single card beast as well."

sole test of the validity of any idea is experiment."
