Please, folks, STOP the "better OS" debate. We are here to talk about fixes for the external display issues on MacBook pro 16.
Peace & Love
That’s where the conversation is heading, which is not strange when you discuss problems. Deal with it. Peace.

I tested beta 9. I can confirm that low power mode still works.
I think in this point we can say that Apple in Monterey is really "fixin" it and it is intentional. Sad we had to wait 2 years for that and 14 watts in normal mode is still not a fix we all want. I really doubt it gets better in final release than 14W in normal mode. But better something than nothing. At least we can silently browse the web and do the office stuff with 2 displays attached in low power mode without the jet engine on the desk. And imo Apple definitely will not mention the "fix" in final release notes of Monterey.

In Windows 10 under bootcamp with the latest offical AMD drivers its 14-15 watts when conencted to an external monitor.

I striped out the drivers that Apple provides under in Bootcamp windows 10 and installed offical AMD drivers for the mobile 5000M series and still the wattage is at 14-15 watts. It's actually worse under Windows 10 now because low power mode in macOS 12 brings the watts down to 6-10 watts.

My take is that AMD drivers for 5000 series are not as optimised as Intel or Apple GPU drivers.

Why is the 5600M not effected???

I believe its do with the memory used in the 5600M which is HBM2 memory which is much more efficient than GDDR6 used in the 5300M and 5500M models.

The previous 15" Macbooks used GDDR5 memory.

The M1X 16" is rumoured to use LPDD4X or LPDDR5 for GPU memory.

The iMac 27" 2020 uses the 5000 series GPUs and they also have high GPU watts usage when using an external monitor and its less noticeable on a desktop Mac.

It would be VERY interesting comparing the efficiency between the M1X GPU and the 5x000M GPUs on the 16".

What do you guys think?

Here's the screenshot for Beta 9 Low Power mode on & off.

Calm down man. People aren't really interested for the M1 vs Intel debate on this thread. Most people aren't willing to switch to a PC either. We all bought a Mac which is essentially defective. Implying that it's customer's fault for being too locked-in to Apple computers doesn't help here. For instance, I can't just quit using Logic Pro X after years of professionally working with it.
There's false advertising, denying & gaslighting from Apple regarding this issue. We have to figure out solutions to this problem, and how we can hold Apple accountable to it. Buying a new M1 Mac is NOT the solution if you think that way.

How can we hold Apple accountable when the stupid issue also occurs in Windows 10 on the 16" MBP and other AMD GPU computers?

More like AMD needs better drivers as I have used this 16" Mac in Bootcamp and with offical drivers from AMD, its 14-15 watts as well.

Anyway, I am not saying buy M1 because thats silly. We have to use what we have now buying new Macs is not an option, I know that.

Hi mihirdelirious, I use the macbook for music production too (Ableton and MaxMSP mostly, but also Logic occasionally).
In your opinion, is it already possible to work with beta 9, or are there issues? I badly need to work with two monitors, but I never used a beta OS before.
Thanks.

In my opinion, Monterey Beta 9 is NOT stable for music production. I experimented for a few hours. There are some CoreAudio crashes while using Logic, and third-party plugins (SoundToys, Waves, Helix Native) randomly crash too. There's also audio interface driver issues. Not worth the risk. You could lose your recordings/data.

It's stable enough to surf the internet, write emails, word documents etc. though.

Good to know, thank you! Better wait, then.

Forcing it to be tied to CPU-crippling low-power mode leads me to see it more as a slap in the face than a "fix". It's like "Ha ha we could have done this all along but we just ignored it, but now we'll do it to serve our own ends in making a new feature." And on top of that it doesn't really serve a purpose in said new feature. I mean the main time I'd want to use a low-power mode anyway is when I'm on battery and not connected to an external monitor, and the discrete GPU already uses lower power then.

For me this is good news—apparently they found a way to keep the GPU wattage low without sacrificing GPU power?!
They definately sacrifice CPU power. I have ran Benchmarks on Wolfram Mathematica, doing matrix multiplications, Discrete Fourier Transformations etc, and the score is 20-30% lower in low power mode.

Also, there is no low power mode in Bootcamp, so GPU is still at 20 Watts if you use Windows on a mac.

The only way to avoid this BS is to fork out $700 more and buy the Radeon 5600m model.

Just so I understand, there is currently no way to normally use both the MBP and an external monitor, with both screens going, without the computer over and fans blaring? Am I understanding this correctly?

Some of us have waited for the last 4+ years to upgrade, I’m on the mid 2012 Retina, hoping to get the latest MBP without the keyboard issues and Touch Bar. As a photographer and editor, the only way I’ve ever used any of my computers is by having, at a minimum, two displays (including built in ones) going.

This is incredible to hear. I refuse, on principle, to run my brand new $5000+ machine on “low power mode” right out of the box. That is assuming the new machines will have the same issue.

Will they? I guess I will not be ordering on the first day, and I’ll have to wait some more to see what the results are from early adopters and reviewers. This is pretty insane.
You can update to MacOS Monterey, and use Low Power Mode. Then if both internal and external monitors are at 60Hz, the GPU does not overheat and stays at 5-10 Watt. CPU is a bit slower in low power mode (~ 20% slower in my Wolfram Mathematica benchmarks), but still usable and that is acceptable to me. If you use High Power Mode, or if you boot into Windows Bootcamp, then power consumption jumps up to 20 Watts and there is overheating and fan spinning.

We can blame Apple for restricting us to crappy AMD GPUs and for getting out of their way to block Nvidia eGPUs ever since Mojave.

Can also confirm fix is still there on beta 10. I also gotta say Beta 10 is smooth on my 16", the previous beta felt a bit slow but this beta feels good.

How's your typing experience? When "Automatic Graphics Switching" on? and without external monitor. I have always lag while I am typing after updating Big Sur.
