[TR] AMD reveals K12: New ARM and x86 cores are coming

It would probably need some kind of special hybrid OS as well, something that runs x86 as well as ARM code, and I wonder how willing Microsoft would be to design that, rather than force a machine with a K12 to choose between the OSes for each instruction set. i can just imagine the drivers for such a hybrid OS...would be interesting to see how they'd do it.

So many hurdles not even counting those in the CPU itself and so many unanswered questions...

They are not planning to have both ARM and x86 cores on the same die. Either or.
It's only the socket and the chipset that remain the same for both architectures.

My bad...I didn't read the article in enough detail....what I skimmed made it seem like they were putting both on one chip...
