With no new GPUs in the works by either of the two main manufacturers, AMD and NVIDIA, this year’s Computex event isn’t going to be a very big exhibition of graphics cards. Instead, Intel’s LGA2011 and AMD’s AM3+ platforms are going to steal the show. It does leave graphics card manufacturers some attention, if they come up with something really out of the ordinary. PowerColor wants to be one of them. Flexing its in-house engineering muscle, the company is readying a dual-GPU graphics card that makes use of two 40 nm “Barts” GPUs for a CrossFire on-a-stick solution.
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. The cooling solution is not pictured, but expect a multi-fan heatsink that spits hot air into the case.
