Power of Powercolor

HD 6870 X2 and HD 6970 X2 

AMD had plans to launch a dual GPU video cards based on two chips Barts and the HD 6990 model built around two core Cayman rebate did decrease the frequency has little power consumption, and so W 375 than standard ATX. PowerColor But he felt responsible to remedy these two situations.

So this year at Computex, we introduced the Radeon HD 6870 X2 and HD 6970 X2. Own creation. And in both cases the connection between the GPU is made ​​by a Crossfire bridge, but through the Hydra 200 chip in LucidLogix, allows these boards are working together with any other model on the market, regardless of manufacturer.

As seen in names, there are two video cards with all the specifications nominal GPUs. This has been put on a second, maximum performance and desired. The Radeon HD 6870 X2 TDP's event was not a problem. This card comes with two GPUs so incorporating each Barts 1120 Stream Processors, 32 ROP's and 56 texture units, and are offered each 1 GB GDDR5 256 bit memory.

And the frequencies are 900 / 4200 MHz. The card is cooled by a dual slot cooler with two 120mm fans, heatpipes and oversized radiators, and electrical needs two PCI-E connectors, eight-pin and six-phase supply. And that gives us the DVI outputs sites, two sites miniDP and a HDMI 1.4a.

Radeon HD 6970 X2 is even more impressive. Overlook the fact that its Cayman active sites have all the 1536 stream processors, 32 ROP's and 80 texture units active, and it works with 2 GB GDDR5 memory and 256 bits. And that has frequencies of 880 / 5500 MHz.

And we at least stop the cooling system needed: a triple slot cooler with two fans, one 120 mm and the second 140 mm heatsink with heatpipes and a larger exchange surface. The board has three connectors having eight-pin PCI-E mediated by an eight-phase power. And the video outputs are the same: 2x DVI, 2x miniDP, 1x HDMI.

It is not yet clear that these cards will find their way to stores. But if they succeed, will require very competitive prices to prevail.
