What affects the "cucuruzesti" MHz in ARM processors?
For example, if you take quite popular on WM devices Intel Xscale 520мгц, and compare it for example with a Snapdragon (for purity of experiment, its frequency is also 520мгц) their performance would be equal? If not, what factors influence it, and who from this pair will be faster on a single frequency?
Actually there is often write ARM7, ARM9, ARM11 — what's the difference? Maybe there's a sensible comparison, and a description of the differences, and even in Russian?
