Apple The Apple/ARM rumor du jour is that Apple will transition its entire portable Mac line to ARM-based CPUs, dropping Intel altogether. Sources speaking to Semi Accurate claim this is a "done deal," and the move should happen by 2013, when a 64-bit ARM A15 core becomes available. While a future generation of Apple's A5 processor could make some sense for something akin to the MacBook Air, the claim that Apple will ditch Intel wholesale for ARM just doesn't add up.

Please take a look at

Note that 2 of the top 10 are running Power/PPC.

x86 is just cheap and easy to get. The Intel/AMD based systems are running close to 200,000 cores.

x86 didn't get any major performance improvements until they replaced the back-end with a RISC core and did a lot of work on the front-end to recompile the x86 instruction set into a RISC instruction set.

Look at the Intel/Atom. This is the low power version and to meet power consumption requirements, they had to simplify the x86->RISC process and remove out of order execution. The performance on this chip is bad and it still runs hot.

Microsoft is using PPC for the xBox systems for performance reasons.

Apple dumped PPC only because of a lack of a road map for Desktop processors. PPC today is used mostly in servers and embedded systems.

Your perceived lack of performance on the ARM chips is mostly caused by not know what the ARM market is. ARM was created for and is mostly used for embedded use. Thus, power usage is more important then speed. The A9 ,at half the speed of the Atom, is still faster; there is no reason why you couldn't clock an ARM at the same speed as an x86 process. The overclocked ARM would still use less power and give you much better performance when compared to x86 chips. If you want even better performance in ARM, you could always add in some of the x86 type tricks to speed things up; of course doing this will increase the power consumption which is why ARM hasn't gone this route.

Nope, is easy to get better CPUs. It's just that WinTel is the major player in the desktop market. Just for reference the ARM market is much bigger then WinTel.
