Take home point: "In fact, POWER* is a unitless measure because it is a semi-arbitrary combination of two measures with incompatible units."
*POWER = "Energy Impact."
- nnethercote 11y agoFor 10.9, POWER and "Energy Impact" appear to be the same. For 10.10 "Energy Impact" has changed.
- kevinchen 11y agoSince the formula is Power = ((used_us + IDLEW * 500) * 100.0) / elapsed_us If you believe that each idle wake costs you on average the same energy as 500us of computation, then the units are compatible right?
