90nm has been a very very slow and poor transition for both intel and amd, and IBM. There has been a little talk of 65nm, especially when speaking of multi-core cpus, and everyone seems to think 65nm will actually work. I'm thinking at 65nm all hell is pretty much going to break loose since at 90nm the voltage requirements don't scale well at all when compared to 130nm. I think we've hit basically a brick wall when it comes to getting smaller with the current technology. Is there going to be new ways of making circuits or are we going to have to rely on a revolution, SOI or Strained Silicon?
