Just a couple of weeks ago AMD officially launched the new Cayman-based Radeon 6970 and 6950 graphics cards as part of their high-end, enthusiast level lineup. Both products are built on the exact same 40nm GPU silicon and are equipped with 2GB of GDDR5 memory as well as 256-bit bus. But differences in shader count and clock frequencies set these two into their own price and performance bracket -- $300 vs. $370 and a . The process is reported to have been successful with AMD engineering samples, as well as on the HIS and Asus retail versions of the card. Just a few words of caution though: be sure to back up your existing BIOS before you play with it and know that you may be voiding your warranty.
