Sapphire has released a new version of the AMD Radeon HD 6670, the Sapphire Radeon HD 6670 Ultimate. I hear you ask; what makes this card "Ultimate"? It's the cooler; a dual direct contact heatpipe based aluminum fin array that wraps around the card. All this means passive cooling, which also means silent card. We last looked at a Sapphire Ultimate offering a little over a year ago, with the Sapphire Radeon HD 5550 Ultimate and the new HD 6670 Ultimate cooler is very similar to that, with some improvements.

The Radeon HD 6670 is based on the Turks XT GPU core, which is a 480 Radeon Core design with 6 SIMDs and 512MB or 1GB of GDDR5. The Sapphire Radeon HD 6670 Ultimate isn't any different in specification, despite the passive cooling solution:

When we first reviewed the Radeon HD 6670 we stated it was a card for providing reasonable game performance in a small form factor and low power budget. This case has now been supplanted by another AMD product, the AMD A-series APU. While our first tests of the APU showed that the HD 6670 is still the performance king over the A8-3850 APU graphics - a fact AMD notes by their naming of the graphics inside the APU, as Radeon HD 6550D - combining the two should give a sizeable performance increase. So does the Radeon HD 6670 Ultimate still have a place in the bold, new, APU world?
