Intel is pretty much wiping AMD off the planet at the moment. When AMD released the popular athlon 64/X2 chips, it awakened the beast within Intel to actually get off their butts and actually create a better product, and with the core 2 duo chips, they have had great success with. We still might have been in the Pentium 4 age if it wasnt for AMD. The smaller company forces Intel to work again.
Now If AMD does get shut down, then prepare for another Pentium 4 era...high prices and little changes.
