Analysis: Interesting marketing that works

I have been around to vividly remember 350 nm and the first Pentium and AMD K5/K6 processors, and since that time, I have tracked the microprocessors and GPU market. It went swiftly from 350 to 250nm and later to 180, 130, 90, 65, 45, 32nm, and 14nm. It took some ten significant geometry shrinking and power reductions to get to 10nm and even to get to 7nm. Apple, in collaboration with TSMC, is just months away from announcing 5nm chips, but the real question is, do nanometers matter?
