techPowerUp posted a review on the ATI Radeon HD 2400 XT

ATI's new Radeon HD 2400 XT comes with the RV610 GPU which is built in 65nm. This means the GPU is cheap to make and consumes very little power. AMD has also added several new power savings features which makes this card one of the least power hungry on the market. For a price of only $79 you will be able to play back HD videos on almost any CPU using an HDMI + HDCP + Audio link with the UVD HD video acceleration hardware.
