So how small are individual components (e.g., transistors) nowadays? Presumably there's a lower limit: once you're a few atoms across, it seems that you can't go any smaller (?).
This is about increasing output per machine via upgrades.
some gates are only 10-14 nm wide, thats about 50 silicon atoms!
Gates are about 30-50 nm wide, even though they're called '3nm' for marketing reasons.
