M1 Pro First Impressions: Core Management and CPU Performance

100 watts? That implies that with serious use you could burn the battery to zero in an hour. Apple's graphs don't show more than 60 watts at peak, and no one is reporting heavy fan output even when running extended benchmarks.

1. Yes, about 100 watts.

From Anandtech[0]:

> Finally, stressing out both CPU and GPU at the same time, the SoC goes up to 92W package power and 120W wall active power.

2. Yes, you can burn the battery quickly under heavy use. I've killed it easily in about 2 hours during heavy Unity work.

3. When I was doing that, I did experience heavy fan output, about as loud and as hot as my 2018 15" MacBook Pro. After the heavy utilization stopped, it cooled down much more quickly than the older Intel machine.

The 14-inch MBP with M1 Pro (not Max) burns 69W under full load (including GPU), so it does run through its 70Wh battery in 1 hour and 9 minutes[1]. (The 16-inch Notebookcheck review is not published yet.)

There are reviews where they actually burn through the battery in an hour. This is not surprising: the M1 Max model can consume 70 watts, plus the display consumes tens of watts in HDR mode.

In a 16” at least, the Max can go up to 92W per anandtech’s initial test, and display + ram + rest brings the wallplug draw to 120.

You're correct (I couldn't look it up and wanted a safe figure that still proves my point :) )
