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.
The information published elsewhere suggests that ATI will use GDDR5 to a great extent, which surprise us a little. On the other hand, ATI may know something about GDDR5 that we don't (we would be surprised otherwise). RV770 has GDDR5 support, but whether ATI will actually use it remains to be seen. GDDR4 with most of the high-end cards is a highly likely scenario. The frequencies suggested here are actually lower than what good GDDR4 chips are capable of.
RV770 will break 1TFLOPS, while the R700, with two RV770, should be capable of twice that, more than 2TFLOPS. This is higher than what he had expected, but then again the core frequencies are also higher than expected. All cores are made by TSMC and their 55nm process. We're still trying to hunt down more reliable information on the design of the "core".
