Introduction

PowerColor Logo


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.

The Card

Unlike the HD 6670 board that we received from AMD, the PowerColor HD 6670 is a full-height design.

The card requires two slots in your system.

Monitor Outputs, Display Connectors

Display connectivity is one DVI port, one full size HDMI port and one analog VGA output. AMD's display output logic is clearly superior to what NVIDIA has to offer at this time. Board partners are free to combine several TMDS links into any output configuration they want (dual-link DVI consuming two links) - and use them all at the same time.

An HDMI sound device is included in the GPU, too. It is HDMI 1.4a compatible which includes HD audio and support for Blu-ray 3D movies. The DisplayPort interface is DisplayPort 1.2 compliant which allows the use of a DisplayPort hub to connect multiple monitors, or daisy chain them together.


You may combine up to two HD 6670 cards from any vendor in a multi-GPU CrossFire configuration. A physical CrossFire connector is not present, the cards will transfer all data across the PCIe bus.
