Just so everyone is aware of the scales involved in modern circuits, an entire CPU Core like in Snapdragon 865 might only take up an area of ~3mm2, measuring just ~1.75mm across. 3mm gets you across the CPU and back again. We think in nanometers and picoseconds down here. (Not withstanding signals travel much slower than the speed of light in our tiny copper wires, remember t=RC)
