Introduction

AMD has recently launched their Radeon HD 4650 and HD 4670 cards which are positioned in the lower midrange sub-$100 segment. The cards are designed to have enough 3D performance for casual gamers and all the great video playback features that ATI has produced over the years: UVD2, HDMI via adapter, HDCP and integrated HDMI audio.

Today we have the HIS Radeon HD 4670 IceQ Turbo on the testbench. It is equipped with a fan made by Arctic Cooling and sports a slightly increased core clock of 780 MHz.
