One thing i am sure is that it will be a lot more expensive that any XP o P4, especially the first chips that will be only for servers solutions. I am not sure when desktop hammer will be available.
Although i think they will be cheaper that Intel 64bits solutions (Itanium 1 and 2) just like Athlons XP with P4.
I am still not sure if 32bits programs will run better with the Hammer (since it will be clocked lower than Athlons).
We will se the true power of this baby when we finally use 64 bits 0S, he and Games.
Have anyone use or see Windows XP 64? How well runs?
