Sapphire Radeon HD 6670 and Radeon HD 6570 Graphics Cards Review
The Sapphire Radeon 6670 Graphics Card
Sapphire packages their 6670 board in a box which follows similar styling to many of their other products, highlighting some of the products key features. Inside we find a short manual, software CD, DVI to VGA dongle and invitation to Sapphire Select Club which gives us access to free software and competitions.
Sapphire uses their own custom blue PCB for the 6670 and attached to the front is a rebranded Arctic Cooling heatsink and fan which is designed for near silent operation. Turning the card around we can see that there is no CrossFire bridge on this card and it is powered by the PCIe connector, topping out at 66W.
For outputs Sapphire have gone with DisplayPort 1.2, HDMI 1.4 and dual-link DVI. The 6670 supports Eyefinity (3 screen) and stereoscopic 3D, though the former is more suited to productivity tasks on this model.
In terms of the detailed specifications on the 40nm "Turks" GPU we have a card with 480 stream processors, 24 texture units, 8 ROPS and the GPU via a 128-bit bus has access to 1GB of GDDR5 memory. The card fully supports PCIe 2.1, DirectX 11 and DirectCompute along with acceleration of high definition content. AMD’s usual video enhancements such as noise reduction and colour vibrancy are available and we can also output audio over HDMI if required.
Sapphire clock their GPU at 800MHz with memory running at 1000MHz (4.0GHz) which combined with the specifications above gives us a 3DMark 11 score of P1800.
