It's possible that Intel will release faster 45nm Yorkfield processors this year but that largely depends on AMD's performance.
In Q1 2009 Intel plans to move to Bloomfield only and this is of course, reserved for the most expensive and most exciting Extreme market segment. Intel also plans to have performance and mainstream versions of Nehalem.
Intel looks strong in 2009 and it looks that AMD will have a very tough task to compete Intel in 2009 and AMD’s biggest hope today is that Nehalem will have some issues. Nehalem looks good on paper and we’ve seen a working version at Intel developers forum back in September 2007, but obviously the chip we’ve seen was far from a fully functional production ready part.
