[* black] Every little hump (through which you see that yellow line) is a transistor. By measuring the total distance between ten of these transistors, we can estimate a chip’s manufacturing process—essentially how tightly the manufacturer can pack in all that processing power.
[* black] The techs at
Chipworks confirmedtook out their astute suspicions by using an electron microscope[nano]meter stick and measured the distance between these transistors, which at first seemed very similar to measure the gate pitch—theA6.
[* black] But wait! It turns out that the A7′s “gate pitch” — the
distance between transistors—revealingeach transistor — is 114 nm, compared to the 28 nm processA6′s 123 nm.
[* icon_note] For scale, 28black] Those 9 nm are a bit deal. It turns out that the A7 is roughlymade with the diameter of ten strands of human DNA, or .00028 ofsame 28 nm process as the diametereight-core Samsung Exynos 5410, the current flagship CPU for Samsung’s own Galaxy line. (Compared this to the A6′s old 32 nm process.)
[* black] So what does that translate to? Applying some mathematrickery, this seemingly small change equates to having the same computing power, but in 77%
of the original area. And given that the A7 processor is even larger in area than the A6, that means even more processing power to lead a human hair. That's tiny!healthy, smartphone-laden lifestyle.
