As CPUs become available with faster speeds, they also come with finer node architecture. Why is this? Could they not just make the CPU larger to accommodate more pathways? I understand that there are some power savings with finer architecture, but why would that stop a company from producing a larger and faster chip that was more power hungry, but intend that chip for wall-powered applications?
I just don't quite get it. Bandwidth, impedance… I'm not sure what other factors com into play…
