Thanks captain obvious, the smaller instruction set is the main reason why ARM chips are so efficient, but that the same time is the main reason why they are very slow in comparison.

Having a smaller instruction set hardly makes ARM better than X86.. It just makes them better for low power situations.

X86 is still in the area of 5-6x the performance gap at the same clock frequency as ARM chips.. So it clearly still has the performance advantage in this arena..

Both have their advantages and disadvantages (for example binary file sizes are always larger on RISC based cores) , but I would hardly say that x86 is inferior to ARM.

The thing is, we've long passed the point where performance was the driving factor in most people's computer purchases. The enthusiasts still want the 4 GHz room heaters, but almost all regular people just use their computers to browse the web, write letters/emails, and manage photos. Their needs can easily be met by a low-end x86 or high-end ARM, and they're increasingly shifting away from desktops to laptops/netbooks. So the power usage at idle (for longer battery life) is becoming the more important stat.

I can't say I disagree, although as ARM chips raise in clockspeed, X86 chips may find themselves more comparable when clocked lower.

i.e a 2ghz ARM variant may perform on par and have the similar power usage to a lower clocked x86 variant. If that were to happen, performance per clock starts to mean something again ;)
