Why are the GHz speeds in computers the same after such a long period of time?
In: Engineering
Idk if somebody mentioned this yet but there will come a point where the transistors bridges inside the CPU are so close together that the electrons will quantum tunnel across the bridge whether it’s open or closed. Basically like a light switch turning itself on and off randomly because the wires are so close together the electricity will jump across the gap anyways. So there are upper limits, defined by the laws of physics, on how tightly we can pack the transistors. There are downsides to adding cores rather than increasing speeds but there might not be much of an option. Programmers write sets of instructions and the CPU executes one, and then the next, and then the next. By using multiple cores you have to send different sets of instructions to different cpus. It’s called threading And it can be very difficult for a novice programmer to do correctly. It requires skill, knowledge, and experience to do it correctly. But if done correctly, it can be more useful to have multiple cpus than one very powerful one
