http://alienbabeltech.com/main/amds-upcoming-hd-7970-exposed-a-short-lived-video-card The HD 7970, codenamed Tahiti, launches this Thursday with but without availability for purchase until January 9th when the HD 7950 launches. So it is a paper-launch until the day before CES and you will now have a preview of the reviews that you will get in a few days from the tech sites lucky enough to get one. The most interesting thing about this launch is that it appears that Tahitis HD 7970 may be short-lived. AMDs 28nm yields are known to not be great and the specifications of the new GPU indicate that something strange is going on. The chip itself is quite complex with 4.3 billion transistors but its core only runs at a very conservative 925MHz. Most telling is that its performance is not that great except in DX11 games and especially in heavily tessellated scenarios only about 25% faster than a GTX 580 overall.
