ANE max power is set to 8W is it correct?

Open devalexqt opened this issue 2 years ago • 4 comments

I found in code that you set ane_max_power = 8.0 W whare you get this number and is it correct? In my AI test (mac mini m1) with optimized coreml model with 3 parallel threads I get only 5655 mW (72% in your math) from powermetrics. Can anyone confirm if it got over 5.7W utilization?

As mentioned here: https://github.com/tlkh/asitop#how-it-works There is no official source for ANE max power. The maximum I’ve seen on my M1 Max is about 7. Therefore I guess the limit to be 8. In terms of specs, the same ANE is present across the whole M1 line-up.

Is it any options to present on mac to enable "High performance" mode? May be m1 is just start throttling because he share TDP package with CPU and GPU as it's place on a single chip?

High performance mode does not increase the TDP, it just makes the fan curve more aggressive.

Can any one confirm what new Macbooks 16" with m1 pro and mac CPU has same performance/TDP for ANE?
