Thread: GB Radeon HD 7970 OC selective 1st appearance

We have acquired an exclusive first look at GIGABYTE's upcoming customized Radeon HD 7970 video card, the GV-R7970C-iii GD. The GB GV-RV7970OC-iii GD has been customized through GB from the printed circuit board, to the heat sink and fan unit, to the out-of-box overclock.

We have been expecting to acquire our hands on non-reference Radeon HD 7970 video cards, and this one appears to not dissatisfaction. We too have a customized XFX Radeon HD 7970 on its path, and an ASUS Radeon HD 7970, which we will have complete ratings on soon.GB has overclocked the Radeon HD 7970 from 925MHz to 1000MHz out of the box.

When this overclock is a bit tame for the Radeon HD 7970 graphics processing unit, it should give you a slender characteristic to function equated to standard Radeon HD 7970's with no attempt on your component. From our overclock trying, we familiar the Radeon HD 7970 is capable of going a lot higher, so we expect forward to overclocking this video card since it has custom cooling.

GB is utilizing what it dubs the "Wind force 3X" cooling plan with "Triangle Cool" technology. It is a lot of fancy phrasing that commonly means there are custom fans and a custom heat sink. The heat sink itself is aluminum with iii 8mm



copper heat pipes, and is sectioned into 3 units. The random access memory too has a heat sink in place which creates exact contact with the primary heat sink, meaning the random access memory is actively air cooled as well. It is good to see this characteristic, we do not see actively cooled memory on a video card so often these days.

The fins of the heat sinks are an concerning characteristic on this video card. Rather of flat heat sink fins GB has alter the structure of the fins through including a clip down the center which elements a slightly triangle shape, which GB mentioned will increase heat transfer and minimize air turbulence.

This is just on the primary heat sink right atop the graphics processing unit however.As we stated, the video card is overclocked to One GHz. The memory stays at the reference clock velocity of 5.5GHz. Since GB has focused heavily on the customized cooling of this video card we can not wait to see what overclocking possible this video card has.

We have the first example of this GB video card, and as such we do not have the last retail packing now to show you, only the video card. The PCB on our video card is really black, dissimilar the blue one demonstrated in the presentation above.

There are 3 heat sinks, linked with heat pipes, with the triangle core on the center heat sink, and 3 big fans to maintain these entire cool.
