Default Re: Official Radeon 7970 Review and discussion thread

Gigaybyte Non Reference 7970
The first picture of a non-reference design AMD Radeon HD 7970, which comes from Gigabyte. The GV-R797OC-3GD is a factory-overclocked card, which makes use of Gigabyte's Ultra Durable VGA+ PCB and custom-design triple-fan WindForce cooler.

The Ultra Durable VGA+ PCB uses a 2oz copper layer for better electrical stability and heat distribution, ferrite-core chokes, low RDS (on) MOSFETs, hand-picked high-performance GDDR5 memory chips, and more. The cooler sports a combination of heatsinks and aluminum fin arrays to feed heat from the GPU, memory, and VRM to its copper heat-pipes and ventilated by three fans.
Powercolor 7970 (Expect a huge o/c on this one)

PowerColor is a major AMD partner and we already saw their Vortex cooler in action back on the HD 6970. As far as the PCB is concerned we don't have much details other than it has a beefier VRM and that the card will draw power from two 8-pin PCI-Express power connectors so we guess that it could end up with a nice factory overclock and more overclocking room when compared to the reference card.
