I'm considering a new iMac purchase, and trying to find out Idle and Max Power consumption for a couple of different configurations - i5 3.2GHz M390 (2GB), and i5 3.3GHz M395 (2GB). I realise amount of installed RAM and differing storage options (e.g. SSD or Fusion) will have some effect, but CPU and GPU account for the lions share of power use under load.
Apple has a useful page here, but lists only one Late 2015 27" configuration.
i7 4.0GHz M390
Idle 63W, Max 240W
That's a start though, and enables a quick calculation: Intel lists the i7 TDP as 91W, and the i5 TDP as 65W here. That's a difference of 26W, so I can estimate a lower configuration:
i5 3.2GHz M390
Idle ??W, Max 214W
Unfortunately without knowing the TDP of the two graphics cards (M390 2GB vs M395 2GB) I can't estimate power consumption for higher configurations.
Does anyone know how much power the i5 3.3GHz M395 iMac uses when idle, and under full load?
Or alternatively, does anyone know TDP or how much power the M390 2GB and M395 2GB graphics cards can pull, as used in the iMac?
