Not long ago, AMD released their Radeon HD 6670 which is supposed to bring fresh wind to the low-end $100 segment. The new mainstream chip from AMD called "Turks" is looking to be a trusty "Jack of all trades" at a valuable market price-point. PowerColor's HD 6670 is a reference clock speed implementation of the HD 6670, even though PowerColor is using their own thermal solution and a modified PCB design which enables additional cost optimization.
