Request: can some with M1 Max run this Powermetrics code to test idle + load power draw?

Refer to my 2nd result. I A/B tested 4 times to be sure and my first result seems to be caused by the MacRumors website.

Opening MacRumors on iPhone Safari is known to be a massive battery drain. The problem seems to exist on Mac safari as well.

Watching the YT video you suggested - MacRumors open in another tab
ANE Power: 0 mW
DRAM Power: 712 mW
CPU Power: 4052 mW
GPU Power: 28 mW
Package Power: 7042 mW

Watching the YT video you suggested - MacRumors tab closed
ANE Power: 0 mW
DRAM Power: 217 mW
CPU Power: 147 mW
GPU Power: 3 mW
Package Power: 595 mW

I wonder if the video was in cache for the second run. MacRumors is a resource hog, though, that's been known for years.

Just another datapoint:

Surfing MacRumors forums will draw 17-20W total vs surfing 9to5mac main page at 9-11W.

This is total system draw measured at the charging port (battery at 100%).

As compared to above results, when Powermetrics is showing Package Power at 300mW. Total system draw at max brightness is about 10W. At 5 ticks brightness, system draw is 4W.

CPU Stress Test at max brightness
package power: 31.2W
Total draw: 49.5W peak

Running GPU and cpu stress tests can push total draw above this.

Little tip for better stats on M1, install `asitop` on terminal via `pip install asitop`.
Much better visual representation of powermetrics:

Thanks a lot, great tool, saw it on MaxTech Youtube videos but they never called its name.

What is the load on the CPU or overhead that this app does vs what is being relayed to the end user running it?

This is quite interesting. Art compares the M1 Pro & Max with the same 32GB RAM

 

[obwohl]

But he's not comparing 16 inch 32GBPro vs 32GBMax (32cores or 24cores). That's the most interesting upgrade but nobody compared those two setups when idle. We're still guessing.
Very important as well: 16 inch pro 16GB vs 16 inch pro 32 GB (to answer the question directly if the RAM drains the battery)

I have 64GB Max and 32GB Pro. How can I best compare RAM power usage between them?

Due to the larger Heatsink of the Max, for low loads, will it run at lower temperatures than the Pro who has a smaller Heatsink?
