I do not understand what you want to achieve. Both Apple and AMD say it ”works as designed”.

Apple has made no claim about noise levels or GPU heat dissipation.

Feedback is of course always meaningful, but the next generation is likely to be Apple Silicon instead of power hungry Intel and AMD chips.

Huh? They released a statement? So they designed it to overheat and run on full blast under low load with an external? All indications from customer service points that Apple denies any heat or fan issue, but they also say the heat and fan shouldn’t get to near unusable levels with just an external monitor connected and one video playing. This is a MacBook Pro?

The question about lawsuit or change.org is to hopefully push Apple to address/offer a solution to a hardware/software defect that almost entirely handicaps a very standard usage case. Don’t understand the confusion. It’s pretty self explanatory. “Next gen will solve our problem” isn’t really logical... it’s basically a “sorry dude. Spend another 3k on next gen device so you can use your monitor while you work.” Most of us don’t got 3k lying around at a moments notice.

What’s more confusing are the people that disagree with finding some kind of strat to get Apples attention for a real issue. I personally really don’t get that.

If they both intend this as desgined then it sucks! This is not a way to treat their customers by selling a pro product with a faulty design that makes it super annoying and at times very difficult to use their product they way they had advertised!

I don't like it either but you have to see it through apples standpoint. Intel promised to have the 10nm cpu ready in 2015. As they designed the MBP 16 they calculated with an Intel 10nm CPU.
Intel didn't delivered so they had to use a 14nm CPU which was not planned. In hardware development its not like you can make a redesign in a few weeks... its about years!

So what apple did is to deliver what they had and as long it's inside the specification they could do that. What should apple do instead? Postpone the release of MBP 16 for 1-2 years because of intel?

Because of these problems they dropped intel. And this decision was not made this year it was already made about 5 years ago but as you can see it take years to make a change like this....

For a customer it sux but there is no real alternatives apple could do...

This has nothing to do with the CPU. The additional heat from the external is caused by an unnecessary power draw from the GPU. The macbook has no business Jumping the gpu from 6w to 20w simply because it’s connected to a monitor. Read the thread. A lot of informed people have been positing that it could be fixed in a driver update. Apple shouldn’t be forcing the GPU to use dedicated at 20w at all times when the integrated gpu is more than adequate to run an external. People with personal connections to Apple engineers have said that they’re internally aware of it, but it’s no where a high priority for them right now because of the ARM transition and iOS14. You’re defaulting to protecting Apple a bit much. They’re thinking about the bottom line, not you.

And it’s a bit foolish to think they’re moving to ARM just to make “better” products for the consumer. lol. It’s a strategic business move. An enormous amount of upsides for Apple operationally.

Again, any class action viability to push for a fix? Or existing change.org petitions. Etc would maybe be helpful.

This is pure speculation. I read this thread carefully but i don't saw any evidence that this is outside any specification.
I saw this problem with MBP 15 2018 and 2019 as well. So nearly every GPU is affected except the 5600M due to the HBM2 memory.

The fact is that the heatpipe design is not suited for this thin laptop and this cpu / gpu combination including the limitation that the dGPU has to be used always if external display is connected.
Everything else is just about how can you optimize the system for a limited design like this.

it’s not speculation dude. It’s been recorded by istats. The GPU jumps and it’s not necessary.

Aside from that, I want to keep the topic of Class action viability for this going too, so it can at least be deservingly acknowledged in some way.

so you got a offical statement by AMD that is not inside the specification to drive an external display with the dGPU? As is said its pure speculation what is causing this and if its running as designed or not as long as we have nothing officially.
Maybe the drivers are not perfectly optimized maybe its something different who knows... but if its so easy like this amd could have fixed this already years ago.

I was able to use my older MacBook Pro with an external fine in the past, although fans would obviously turn up under load. Pretty much automatic high heat and high fan noise though is a new development with the recent model. Apple website even has a tutorial on how to use the MacBook w an external. It’s an implied usable feature that’s not really useable with the 16. And the issue that it runs an external with its dgpu isnt the problem. The hard facts is that it jumps from 6w to 20w automatically right at connection. The dedicated is supposed to be able to run 2x 6ks, and it needs 20w to run a simple 4k?the internal gpu doesn’t even need that much. Lmao.

If it was such an existing problem wo all the MacBooks, so many people wouldn’t be complaining about it like its a new issue. that’s why I feel like aclass action or change.org might have some merit.

You're mistaken. It's not because of the CPU, it's because of the GPU and the drivers supplied with it. MacOS should have been optimised for this. It's largely faults of Apple engineers! This is in line with declining quality of Apple softwares in recent years.
 
Idea: I guess that many of us have LinkedIn. Try to find there Apple engineers in the MacBook Pro section, specifically GPU engineers, and send them a message. If the support doesn't do their job, we'll help them. We will make the engineers aware of it directly, without the help of anyone. We gave them a chance for more than half a year, now we have to do some creative stuff.
 
Hi guys,

I just created my account on the forum to reply in this topic. People who says that this is a driver issue are 100% right! How is it possible that my Macbook's screen which is 3072×1920 consumes 4-6W of my Radeon GPU on idle, when my 2560 x 1440 27" DELL screen with LOWER resolution than Macbook consumes 18W constantly also on idle (both running separately with Radeon 5500M dGPU enabled). And if that wasn't enough, when I'm opening 4k video on chrome using my Macbook screen, GPU power usage is ~11W which is still way better than with lower resolution external display doing absolutely nothing! We need a driver update ASAP, that's the issue.

Its both and of course the design of the heat and airflow.
But you can read a few statements from ex apple employees that the main issue with the heat is caused by the CPU which should be more efficent and made the problem worse.

And i can just say i have exactly the same problem with the MBP 15 2018 and R560X (18W with 4k external display and about 70C while idle). But it seems a little bit better with the latest upgrade.

One word: Kindergarten

If you know tech company operates, especially something like Apple, you would know that company roadmap and backlogs are created by product people, and their direction and focus usually align with company value and perceived user values, and that would be coming from the top, so there is no use to just to contact an engineer.
 
For anyone else naive enough to think that if Apple could fix it they would, just look at support for the first gen Magic Mouse for the iPad. They entirely handicapped that mouse from its multi touch gestures. Apple’s only interest is in making us upgrade and stick within their ecosystem. Releasing products just good enough to motivate that is simply part of that equation. IMO, Apple hasn’t pushed for innovation for the sake of innovation or quality for the sake of quality since Jobs (RIP). Cook has always been the operational wizard and has basically transformed Apple into a corporate monster, while keeping the benefits of the sexiness factor that Jobs established. Cook’s still a great leader, but entirely a different breed from Jobs. His concern is feeding the beast.

Another possible indication that the monitor thing is fixable is that I use my iPad Pro as a second monitor since the MacBook won’t let me and I run at 60 degrees and 1700’s rpm pretty easily. Radeon highside barely pushes past 8. But maybe the processing is done by the iPad in that case? Please Apple, if you’re reading this, don’t ruin this one for me too. It’s been magical.

Anyway, still open to any lawyers that might want to chime in! Finger crossed. Requests like these always seem to get buried. Still no clue why so many people willingly take things in the ass just because it’s Apple. Lol. “No! Don’t bother Apple! Think about what they must be going through! Tim Cook loves me!”. 😆

Here's an additional datapoint: I'm running Sidecar right now on my MBP 16" i9 w/ 5500M connected via USB-C<>USB-C to my 11" iPad Pro as an external display and the dGPU is *not* engaged!! I repeat: I have an external display connected (via the Apple Sidecar protocol) and I'm still on the Intel iGPU with low wattage! The wi-fi on my iPad is OFF and this connection is pure USB-C.

What is going on??

Note: I've left earlier posts on this thread talking about how I suffer from the GPU issue being discussed, so this Sidecar situation is an anomaly.

Good news.
Curious if monitors like are gonna work without dGPU too:

This is because SideCar uses the network to send/receive data for the display.

@Appledoesnotlisten
Unfortunately and portable monitor will not be a solution.

In other topic:
Just saw this comment on Apple Forums where some user used this product to run the external display via USB avoiding the GPU bien activated at all.

Can you link to that thread please?
 
If suddenly your entire WIFI network is crushed and running dog slow it's because of Sidecar. Spent hours troubleshooting my network settings and hardware only to shut off sidecar and it instantly going back up 210Mbps from 15Mbps..
