AMD out from Hibernation, but Intel never slept?

By this April AMD will roll out its long famed Barcelona Quad cores, onto the retail market. They were supposed to do this by the end of 2007 [read here], but unfortunately, some issues like Visualization problems and breakdown at high workloads kept them from going. But, now they have filled in new silica and are all set to challenge the blue chip maker.
Barcelona is the code name for the new quad series of Opterons, and is a continuation of AMDs quest for dominance in the multicore market. Though most feel that AMD is trailing by an year, they are confident and proud about their offering. AMD says this gives better performance and have a cleaner and compact instruction set, and even does not have extra heat dissipation compared to its earlier dual core variants. Already the Barcelona has been deployed in some high profile computer centers like Texas Advanced Computing Center. Now, AMD is looking at vendors like HP, IBM, Dell etc to sellout the new Opterons.
At the same time Intel has announced it would be ready with its new 6 core processor code named Dunnington (sure, even I feel the name is wierd), which is supposed to hit the markets later this year, also the 'Tukwila' (that's the wierdest) project which is a quad-core Itanium with 2 billion transistors, the already famed Nehalem.
Well most feel Intel is ahead now, at least for the next 12 months, but we cannot rule out the Green boy, he has done it before, he may repeat the "Hamilton act" (as we call in Formula1).

P.S. I am sorry for not posting for last four months, I had some personal debacles, but now it is going to be as frequent as ever.
