Since a while, it is becoming apparent: AMD board partner Sapphire is increasingly taking leave of his conventional Vapor-X models and focuses more on the already popular dual-fan solution. These are usually a very good cross between noise and cooling efficiency dar. Even our newest test specimen, the Sapphire Radeon HD 6970 dual fan, its name and makes it familiar to just such a solution.
The cooling system consists of two 90-mm fans, many aluminum fins and five full-thick copper heat pipes and should act so much quieter and reduce the temperature of the chip and memory further, under the hood, but everything remained the same. So here, as usual potter 1536 stream processors and a 2048 MB GDDR5 large video memory, even with the clock speeds of AMD's partners beließ all the same whether in the Sapphire Radeon HD 6970 Dual Fan still be deducted from the reference, we learn in this article.
Even the last Sapphire video card, which we welcomed in the editorial continued, no longer a Vapor-X cooling, but rather a familiar dual-fan solution. In practice, the concept of the Sapphire Radeon HD 6870 Dirt 3 Special Edition certainly fallen, finally we were able to confirm the lower middle-class 3D accelerator low temperatures with good sound effects.
A few days went by and then you also missed its Radeon HD 6970 a fancy dual-fan cooler, the Sapphire Radeon HD 6970 Dual Fan now reached our editors and had to say in our long standing benchmark parcours. Under the hood of the dual-slot cooler, which is equipped with two large axial fans and five thick copper heatpipes, but everything remained the same and so are the jaunty "Cayman XT 'graphics card is still 1536 stream processors and a 2048 MByte GDDR5 video memory, which is the usual connected via a 256 bit wide memory interface, are available.
Before we begin, however, with our tests, we take a brief look at the architecture of the Radeon HD 6970 and its construction, this is also the Sapphire Radeon HD 6970 Dual Fan runs on proven 40nm process at TSMC from the band and has 2.6 billion transistors entertained. While the smaller models of the AMD Radeon HD 6000 family still put on a 5D body, the U.S. decided to forge his image "Cayman" GPU for efficient 4D VLIW design, were the shader cluster yet summarized in five packages, there are now only four groups. Accordingly, divide the total of 1536 stream processors in 24 SIMDs, which are divided again into 16 4D shaders, as used with any SIMD clusters are four texture units, it brings AMD's fastest single GPU so on 96 TMUs.
