PowerColor develops dual-GPU Radeon HD 6870

The two Barts chips will feature the BartsXT (Radeon HD 6870) configuration, with the card being designed to offer performance on par with HD 6870 CrossFire, with 3-GPU and 4-GPU CrossFireX support, and lower power draw than two single-GPU HD 6870 cards. The PCB design is the same as every dual-GPU AMD card ever made, there are two GPUs sitting on either sides of a PLX-made PCI-Express bridge chip, and each GPU system having its own VRM. There's 1 GB of GDDR5 memory over a 256-bit wide memory interface per GPU. Power is drawn from two 8-pin PCI-Express power connectors.
