It's an i5 processor, 2 cores at 1.8ghz. New generation arm processors, for example the tegra 4, is quad core at 1.9ghz.

Wouldn't it be both more powerful and have more battery life, if it had waited for the tegra 4? Or am I missing something?

Yes you are missing something. Processor performance is not simply a function of number of cores and clock speed. There are vast differences between arm's architecture and x86.

How could we compare then?

You are missing something. 2 things, actually.

Cache and instruction set.

Intel is still more powerful than ARM because of its instruction set.

What makes the x86 instruction set more powerful than ARM?
