On modern CPUs, is the TSC invariant to T-state throttling? If so, which
generation did this start happening?
On server/desktop systems I believe that T-state throttling is intended to be a
rare event usually due to bad system thermal design. Is this the case with
laptops, or would we expect to see more? Do any of the forthcoming "turbo"
modes change this?
Thanks,
Ian
