Hmmm.... well judging by how well AMD has kept to their roadmaps for the past year or so, its hard to see what this will do.
They have somewhat kept to the details of the actual CPUs that shipped, but their dates were just way off. I'm not surprised at the delays as the quad-core K10 was a very ambitious project. Even Intel didn't want to touch a monolithic quad-core CPU with an IMC until the end of their 45 nm run, let alone at 65 nm.
So they clearly want to take a stab at Intels Dunnington but if Shanghi is just a 45nm shrink of Barcy, I am doubting to see major performance improvements.
There should most certainly be performance improvements, at least as far as absolute performance is concerned. The 65 nm K10s are very much clock speed limited due to heat production (at least in shipping units) and 45 nm will allow for higher clock speeds. Shanghai will also triple the L3 cache, which may very well give a decent bump in performance clock-for-clock as well. The big L3 cache in Dunnington may or may not provide much of a gain, depending on its latency and the particular applications being used.
But I guess we will see. I also love how they want to go with the 2x6=12.. Funny how AMD critisized Intel for it and now they are planning the same thing.
It is called marketing. Marketers are like politicians and lawyers- they feel completely free to completely contradict what they said a few minutes ago and think nothing of it. Intel criticized AMD's monolithic core designs and said their FSB was good enough but now they are going to a monolithic core with an IMC just as AMD had. And I bet they tout the core design and IMC in their future ads, too.
