An interesting point from a talk from a chap from ARM I remember at uni - there was no good technical reason why intel can't get similar performance out of x86. Their processors are basically RISC inside with an x86 wrapper already. So, intel will lose out because they need that RISC-CISC 'wrapper' but (personal opinion) I don't see why that wouldn't become fairly negligible. The big differences between ARM and intel are licensing and manufacturing, unless Intel have started to licence out designs for cores recently.

I don't think that the wrapper can ever be negligible. It has to do quite a bit of work. Now that work can be heavily optimised, but it is still work that takes power.

... so the latest & greatest x86 may actually be an ARM inside the wrapper?
