(2019) 16" is HOT & NOISY with an external monitor! :(

[davidbend]

Would it be possible to achieve 5-6W with the lid open and without power low mode? Or I must turn the low mode on in order to achieve 5-6W?

 

[JosepPont]

Who do you think wins?

i7 with LPM OFF (5600M)​

i9 with LPM ON (550M)​

​

Thanks!

Hello Guys
I want to share my results with you.
Laptop: MBP 16 i7 5300M 32GB, fresh install without restoring backup.
Monitor: Dell 27 1080P
Adapters left side, power cable right side.
Clamshell mode, LPM ON = 3-4W
Clamshell mode, LPM OF = 3-5W
No clamshell mode, LPM ON = 4-5W
No clamshell mode, LPM OFF = 12.5 - 13W

Geekbench LPM OFF, I was surprised because the results are better than Geekbench i7-9750H, the Multi-core is almost 1k higher.

OpenCL

LPM ON

So we have to find a way to keep this without lowering cpu performance.

So far on my usual workload, LPM has not made my MBP feel slower.
This is with Chrome, Affinity apps, Coda, Excel, Outlook, Safari, Teams...

I'm quite liking LPM

For me, multi thread processing doesn’t suffer much because turboboost can’t handle multi thread fully loaded.

For doing simple things like watching youtube or browsing the web there won’t be noticeable difference.

But for opening things quickly I do noticed some differences because the single core peak performance throttled from 4.8ghz to 2.6ghz. 2.6ghz still usable but just not feel as responsive (1 sec vs half a sec)

For some reason, since Big Sur opening some apps on my MBP 16" is sloooow. Excel, Affinity Designer, Outlook... all of them take more than 5-10 seconds to open.

And I just did a Clean Install to see if I had messes up with something. But it remains the same.
So maybe I just got used to slow launching app, hehe.

I think my next laptop is going to be the 2022 MacBook Air. I'm digging the "no fans" design. Something tells me reliability is going to go way up with less moving parts and dust everywhere.

I'm thinking in the same direction. I do have concern about heat still so I'll try it out for 14 days to see if heat is really not an issue with my usage.

I created two quick shortcut to quickly switch between power modes and keep the screen brightness unchanged.

for the brightness it requires to install homebrew, and then install brightness package.

low power
sudo pmset -c lowpowermode 1

high power
sudo pmset -c lowpowermode 0


extra tips:
brightness
brightness -d 0 0.95

If you already have Homebrew installed, first install 'brightness' into Terminal:

brew install brightness

Once completed, simply use the following commands to control the screen brightness:

1. To increase the brightness to the maximum value:

brightness 1

1. To reduce the screen brightness by 50%:

brightness 0.5

use brightness -d 0 to specify build-in screen only.



Once you done it, use the new Shortcut app to add these.

Tips:
use options icon(three lines) at the top right to also add "Pin in Menu bar"

Unfortunate MacOs automation is not supported.
Otherwise can use it to automatically to monitor cpu load and turn on/off automatically

for me honestly LPM is a game changer. I do full stack development (java and js) and all this involves vms, containers and etc which made my experience "windy" due to excessive fan noise. Now I haven't done any stress tests yet, but so far so good. Fans are silent and I didn't really notice any performance degradation. I am really not used to hearing no fans when opening up my java projects... wow ?

Affinity its a know problem, its bcs of the apple app verification process

True, but heat is also a killer. If a component overheats on a regular base, then expected lifetime will go down as well. Not that I hear anything about the M1s overheating, but it's a factor to keep in mind. In fact, at work I have several M1 MBA users and they couldn't be happier. They switched from a variety of machines (12", MBA, 13" MBP).

Glad to hear it!
May I ask what is your full specification of the MBP?
And how many VMS do you run?

6 core i7 with 32 gigs of ram, radeon 560x. I think it's early 2019 if I'm not mistaken.
About VMs... 2-3 + docker containers (5-7). Been working the whole day today and I cannot believe this is my laptop. Very quiet.

Yep, heat is a killer. So far, as you say, at least it seems heat is not an issue. Not sure in a couple of years with more demanding software how it will behave.
And hopefully the future M2 Apple can improve things further.

I still have an iPad 2 and the first iPad Air. And both still work. The iPad 2 is slow, but the iPad Air is quite decent for Kindle, Solitaire, Netflix.

As for my Macs? Only the original Black MacBook still works. My MPB 2011 15" the GPU melted ?, my MBP 2017 13" the display stopped working, and my current MBP 16" works great, but runs quite hot, until this "fix".

Let's hope Apple is at long last going in the right direction.

 

[Minga089]

Today I upgraded to Monterey (clean install) and I can confirm:

LP-mode: 6-7W (50C at idle)
Normal mode: 14-15W (60C at idle)

Hardware: MBP 16" base model (i7, 5300m) and Dell U2720Q 4K monitor

So far so good.

However, the performance drop imo is quite noticeable in LP-mode. The animations aren't as smooth and the system just doesn't feel as snappy. Especially with web browsing and App launches. But that was expectable since with Turbo Boost Switcher it was exactly the same. I still hope that there is a workaround for the CPU, because I don't think I can live with crippled CPU performance like that for good.

Those are just my first impressions and since I upgraded today the machine is still indexing and doing a lot of things in the background. I will report back in a week or so.

I still use my old 2015 late Mbp 13" for my kid's zoom needs. It got sessior switch, mac-safe, hdmi, sdcard, usb-a, a cool running intel cpu.

Still feels snappy for basic web browsing and zoom and runs like a dream. Also it has the best Macbook pro features (good keyboard, ports)

It is a good investment and still works well after 6 years... The same cannot be said for my Mbp16"... battery degrading fast due to heat.

My report is, the LPM mode is a big disappointment in terms of performance. My system isn't usable at all. It's beach balling all the time, I cannot scroll or use keyboard. Stutters everywhere. What a shame, I need to wait for future releases...

Strange, I have nothing of the sort. I turned it on right after the upgrade and haven't touched it since. Operation is as usual (not doing anything fancy, though, except I fired up a VM just now which works fine) but fans come up only slightly when they otherwise went crazy.

Interesting, maybe I need a fresh install, thanks!

So far I had only 1 problem with the LPM mode: Photos app started to struggle with my pictures (albeit quite large ones, from the mirrorless camera), slowdown and various glitches were very noticeable. Otherwise, everything else works almost exactly the same, just a bit slower.

 

[Marceen]

Thank you guys for all information on this topic. I test LPM on the third day and hardly see any difference. I'm using JetBrains apps, Docker, compiling java apps, using Teams and other stuff. Everything works fine and I have a cold and silent computer. Wow, what a joy after a few years.

14 inch 1TB model - no noise, quite cool. As others hav suggested, see if a specific app is hosing you.

All better after the fresh install!
I'll report after full day of animation work.
