Why are the GHz speeds in computers the same after such a long period of time?
In: Engineering
Used to be that we’d figure out how to cram twice as many transistors on chips every year and a half or so, that’s what we call Moore’s law. Used to be, too, that those transistors which were half the size also drew half the power, but at one point that stopped, meaning you could maybe put twice the transistors on the chip but it would also draw twice the power, meaning it would heat up twice as much, and heat dissipation became the limiting factor, not ability to make faster processors in itself.
