In terms of raw speed, Moore’s Law has broken down for at least six or eight years. Chips have continued to advance in terms of transistors per area and other metrics, but their clock speed now is roughly what it was in 2005
Moore’s Law is precisely about transistors per area, not about clock speed. So it hasn’t broken down.
Moore’s original formulation referred to transistors per area per dollar, yes. However, the same exponential growth has been seen in, for example, memory per dollar, storage per dollar, CPU cycles per second per dollar, and several others; and the phrase “Moore’s Law” has come to encompass these other doublings as well.
If it’s about all of these things, it doesn’t seem very useful to say it’s broken down if it only stops working in one of these areas and continues in the others.
