Hardware, Embedded Systems So, we have Intel and AMD. These guys are doing pretty well in laptops, servers, and of course desktops, but when it comes to mobile devices, they've so far been unable to adapt the x86 architecture to the stricter requirements that come with those devices. ARM, on the other hand, pretty much owns this market at this point. And you know what? It's time for Intel and AMD to get worried - really worried. ARM has just announced its Cortex-A15 MPCore chips - which will reach 2.5Ghz in quad-core configurations.

RE[5]: Microsoft Windows + ARM?

Member since:

Apple also did the same when they transitioned from m68k to ppc...

However what these 3 examples have in common, is that the processor doing the emulation is considerably faster than the one being emulated, and incurs a significant overhead in doing it.

ARM on the other hand is designed for power efficiency, and while the newer chips may be performance competitive they certainly don't have a massive speed advantage over x86 like alpha did. Also the power efficiency is massively reduced if you have such a high level of overhead as emulation.
