I know the faster the clockspeed, the more heat is produced. But lets just ignore that for now
What is stopping a CPU from overclocking faster and faster? Voltage? The architecture?
If neither of those were in play (temps, voltage, and architecture ignored) what would physically be stopping such an imaginary CPU from being clocked higher than what average CPU's can get to? I'm just plain curious on what "bottlenecks" stop a CPU from being clocked higher and higher (and, in what order those bottlenecks are in)
