M1 Max's CPU Maximum power consumption?

[CASMAS]

I ran Cinebench R23 multi core test to see the power consumption just for M1 Max' CPU and I got 28.27 Watt. All cores were being used for sure. 30W is the maximum power consumption for M1 Max, right? I wonder if anyone got power consumption higher than 30W.

I dont think that M1 Max will use more than 30W for CPU. Since GPU uses 60W and MBP limit its power consumption lower than 100W in order to use full power on either battery and power adapter.

Max wattage is around 40w.

For reasons unknown, we have some educated guesses in another thread, CB23 has difficulty running on an M1 core full throttle. It has similar difficulties on AMD cores but that can be masked by SMT2 (hyperthreading).

So as @senttoschool noted the actual upper limit of the CPU cores is about 40W give it take if you’re measuring package power or core only.

Edit: If you want to really stress it, try SPEC - some of the subtests like POV Ray or libquantum should cause it to hit max wattage.

CPU clusters max power usage is around 30-35W, max package power usage (this includes RAM and interconnects) in CPU-only workloads is around 40-45W.
