Sure you are right, still i don't think this is a "fast" cpu, in 620 is clocked at 1.8 Ghz and the flagship is 810 with a 2Ghz A57, i am pretty certain there is no trivial difference between 620 and 810 for market differentiation. Strange enough apparently it looks "slower" clock to clock than A57 to drop the power. A57 is a power hog by default.
