Athlon Rumor Mill has posted some exceptional information regarding AMD's upcoming Rev G processors. Somehow, the editor managed to obtain die shots of both a current Revision F processor as well as an upcoming Revision G CPU. An animated clip overlays the two images and reveals the fact that there are some significant architectural changes. The wild card here is the use of two different stains in the die shots, a fact which can make the same objects look radically different. Regardless, the animation does seem to hint at some major changes though we'll wait for official word from AMD before we dive further into this rumor.
