Radeon HD 4000 series specifications surfaces
 

The ATI Radeon HD 4000 series is slated for late Q2. Information about the high-end RV770 has been leaking onto the web, from here and there, but the exact specifications has remained in the shadows. German hardware site Hartware.net has gotten their hands on what seems to be pretty authentic information. As far as we can tell, it looks believable and matches the rumors going around. We're still far away from the launch and the figures are subject to change. We also have some information on our own to share with you.
