Could you give me some pointers on the actual numbers? My searches came back with nothing. I'm especially interested how they benchmarked the energy consumption

- sjwright 10y agoMost likely they would infer energy usage from resource consumption.
- Someone 10y agohttp://asciiwwdc.com/2015/sessions/712 http://asciiwwdc.com/2015/sessions/712 is the best pointer I know, but it does not give details. My guesses would be that they have a simulator that computes/estimates power usage, and that they have CPU setups where they measure power usage directly. I doubt they regularly do the "compress things till you run out of battery" thing that that talk mentions. That takes too long, and cannot be used to measure small changes in power usage.
- a_imho 10y agoDo you mean by extrapolating from executed instructions? It would be very much dependent on the architecture then. It would be nice to read some independent studies and experiments, after the recent events I take any manufacturer claim on consumption with a pinch of salt.
