    Doing highly CPU-intensive processing, running close to 100% in Intel XTU, I notice that over time the graph for Power Limit Throttling starts spiking up and eventually showing very consistent activity. Yet the CPU activity seems unaffected by this, and keeps chugging away on the work load. What exactly does Power Limit Throttling do?

    FWIW, the temps are steady in the mid-seventies, and everything seems to be working fine, no thermal throttling whatsoever.

    a limit on which your cpu cannot clock higher due to power constraints. So it is at its max.

    So Power Limit Throttling is simply the CPU's method of governing its own speed? I'm guessing that what's really being limited is the CPU's ability to go beyond 100%.
