How does this impact Pentium-M processors (Banias and Dolthan) which are
some sort of P3/P4 hybrid that gets more work done per clock cycle that
straight up P4s.
I thought I heard that Intel recently announced that in the future their
desktop CPUs would be using the Dolthanesque CPUs -- and aren't laptops
about to outsell desktops?
Just curious, since I just ordered a Thinkpad T42p with a Dolthan cpu.
