Not much to be honest. Unused part of the chip is powered down so if you have the maxed out 32 cores GPU M1 Max and only use it to browser Mac Rumors, only the Efficiency Cores are turned on and the majority of the GPU is shutdown too.
RAM does eat more battery the more capacity you put in but not to the point of noticeable drop. Low power RAM sips very little energy compare to normal ones, especially with binning and tuning.
NVME drives only eat more power when you push them with heavy read-write task, they have power saving features too.
Fair enough. Based on the GPU performance graphs that Apple showed it does look like the minimum power consumption on the M1 Pro is about 8W, whereas the minimum power consumption of the M1 Max is about 13W. You don't think those 5W will have any appreciable impact on heat and battery life? I'd love to be able to cancel my M1 Pro orders once I know the Max isn't going to run significantly hotter and last less time unplugged.
 
Hopefully “precisely machined” doesn’t mean a cable that is too short that it will break after normal wear and tear.
 
If Apple truly wants people to be and use these for creative purposes as opposed to consumption, I suspect their claim of no fan activity in normal use is likely false.

My M1 is essentially silent until I am actually doing work in it. Deep image manipulation and video work causes my fan to kick on regularly. That said, it isn’t screaming with the feeling of potential vertical take-off like my i7 equipped MacBook Pro.
 
The graphic lines of airflow don't make sense. How does the cool airflow come in, spin clockwise, then exit as hot from a counterclockwise direction?

The airflow image doesn't make any sense. By the time reaches the actual heatsink to cool down the thermal pipes, it's already hot?

The two fans are centrifuge type which means there is a shroud that covers the fan except for a circular cutout in the middle where air gets sucked in and pressed against the inner wall. One section of the inner wall is open to a channel where the air is blown out. The fan can blow the air out in any direction. Here is an animation:

Now in terms of the air coming in, the image from Apple shows the air coming in from the sides don't passively cool anything before getting sucked into the fans. The top middle air coming in appears to passively cool some components like the SSD drive before the fan since it changes color to red.

The last piece is the heat pipe that runs across the top that's shaped like an upside down mustache and Apple framed it with red lines to show it's hot in the middle, but cooler at the ends. The heat pipe contains a coolant that transfer heat from the heat plate on top of the CPU/GPU (in-between fans) and routes the hot coolant to the opposite ends of the pipe. What the image doesn't show is the 2 ends of the heat pipe each have cooling fins where the air blowing out of the fans is used to cool down the coolant. Yes, the air coming out is already warm because it passively cooled some other components, but the temp of the coolant in the heat pipe is significantly hotter so it will still cool down and send the coolant back to the hot CPU/GPU to pull heat out again.

I don't get the complaints about the notch. It's unused space right now on most PCs, even the new Surface Pro Studio with a 3:2 display. Only the standard Mac menu bar will appear there, which leaves the rest of the screen available for applications. Yes, cameras and sensors can be placed behind displays now, but that has drawbacks too.
The complaint is that it's completely unnecessary and breaks the aesthetic of the screen which is what our eyes are looking at 99% of the time. No one is putting notches on laptops for good reason, because it's idiotic and 100% unnecessary. Most people will always choose a slightly thicker top bezel over a notch. The bezels can be thinned out on the sides and bottom, and a little bit on top with no notch, and that would have been totally fine. No one asked for this notch and no one wanted it. It's only now that it's been thrust upon us that the apologists are coming out of the woodwork doing backflips and mental gymnastics trying to justify this idiotic design choice.

Gamers gonna game. It kind of pissed me off when Apple showed the graphics capabilities of the M1max by using what is essentially a 3D video game rendering of a fictional spacecraft. Totally awesome and at the same time totally pointless. I hope that all this new CPU and GPU capability will be used to improve the real world, not to escape from it.
 
The worst thing about my 2019 16" MBP with i9 Intel chip was the heat.

My legs would burn as the laptop sat on my lap. I would have red marks.

Oh, and the loud fan that always came on while doing simple tasks.

So glad that Apple dumped Intel and found a way to make chips that don't cause your laptop to become a portable heating device.
 
Yep. I can’t wait to dump my 2019 16” MBP.
I couldn't wait and bought the Mac mini M1 like 3-4 months ago. I absolutely hated that hot oven noise making piece of crap.. I only wish Apple could compensate me for the loss of having to recycle it....

This is an excellent question. Thank you for answering it. In the past with Intel Macs, I have opted for higher amounts of RAM combined with the lowest graphics capabilities. With M1 Pro/Max I wanted to buy 64GB of RAM but now the only option is the highest graphics capabilities. Because of battery life and heat concerns, I was thinking of just getting the binned 24 GPU cores.

What you are saying is that for low graphics demands, it really doesn't affect battery life if the GPU is 16, 24, or 32 cores.

Think of a squirrel cage fan. The air enters from the sides and exits from a hole in the circular enclosure. This diagram shows that for this chassis, cool air enters from the sides and center rear and exits to the sides on the rear.

The rear air flow seems possibly problematic to me - why won't the exiting hot air get recirculated into the center port? - but the diagram seems clear enough.

The intakes for cool air (blue arrows) are located either side of the chassis and in the centre-back - the latter being a new and additional location.

The exhausts for hot hair (red arrows) are located on the left and right back of the chassis, connected directly to the fan shroud. The fans themselves are also larger and thicker than the previous models.

Reminds me of the huge pushback when Apple introduced the iPhone with a non-mechanical (glass) keyboard. Doomed to fail.

I suspect some even said idiotic, because people were used to triple-taping pushbutton keys to type a message. And young people were amazingly fast composing messages.

They're not even remotely close the same thing lol

So much to like about these Macbooks but the notch is a deal breaker for me. Windows is excellent these days and offers me a lot more in terms of software and compatibility, and I have an exceptionally powerful AMD based laptop that covers all my needs, sure it uses significantly more power but that's of no consequence to me. Once Apple gets back on track and loses the notch in their future versions and (hopefully) improves their Macbook aesthetics, I'll jump on board. Until then this is very easy to pass on.

But to all those who do get one, I'm sure you will be very happy with this efficient powerhouse.
Such a stupid thing to be a deal breaker. The display next to the notch is outside the 16:10 ratio. It will either be hidden or part of the time menu bar

You’ll be waiting a long, long time.
The iPhone isn’t even rumored to lose the cut out until 2023 *at the earliest*, which basically means that it’s more likely to actually happen in 2024/2025.
iPhone usually gets features long, long before other devices do, so you can pile on an extra year or two before this upgrade would trickle down to the MacBook Pro, and adding on top of that the fact that the MacBook Pro design really only changes about once every 4 to 5 years.
2003: aluminum PowerBooks introduced
2008: unibody MacBook Pro
2012: retina MacBook Pro
2016: Touch Bar MacBook Pro
2021: notch MacBook Pro
So you’re looking at at least 2025, maybe even 2026 or 2027.
Especially if they start adding stuff to that area, which I fully expect them to do.
I expect the M2pro and M2max versions to include face ID, and then maybe the M3pro and M3Max versions will upgrade the camera to a 4K one… basically what I’m saying is the notch isn’t going anywhere for at least a half decade, so everyone expecting it to just disappear in the next update should prepare for disappointment, get used to it and get ready for every other manufacturer to copy it
 
Fair enough. Based on the GPU performance graphs that Apple showed it does look like the minimum power consumption on the M1 Pro is about 8W, whereas the minimum power consumption of the M1 Max is about 13W. You don't think those 5W will have any appreciable impact on heat and battery life? I'd love to be able to cancel my M1 Pro orders once I know the Max isn't going to run significantly hotter and last less time unplugged.
I didn't see your response before I posted. I have the same concerns. In the Intel days you could max out RAM but select a weaker graphics option, which is what I used to do. I want 64GB of RAM, and know that it slightly negatively affects battery life, but have no choice but to go with a 24 or 32 core GPU but don't want to take an additional significant battery hit from potential graphics performance that I'll never use.

This 5 watt difference between the Pro and Max must negatively impact battery life to some small degree. I wonder if the 24 (binned Max) core GPU option has a lower minimum power consumption than 13W.
 
The stated GPU performance on M1 Max is like an NVidia RTX 3070 or 3080. The original TSMC 7nm production process used for the NVidia Ampere GA100 GPU required a massive heat pipe and very significant external cooling when in reasonable use. The Samsung 8nm process in the NVidia RTXes also requires a large heat pipe and significant external cooling despite claims of 2X improvement in watt for performance over the GA100. The M1 Max chip has a 5 nm process. If the M1 Max chip enables workstation like GPU performance with minimal to no cooling, it would be almost a miracle engineering marvel that would upend the GPU market.
 
The exact same response. Apple was blowing it, didn't know what they were doing with the keyboard being used so much. Doomed to fail.
Your anecdote isn't a valid argument against the notch complaints and you're also misrepresenting my position. I never said or implied "doomed to fail". I said it's a deal breaker for me. I'm sure these will do quite well with the already established Macbook user base but some will be buying them begrudgingly due to the notch, as is very evident in these forums.

Unlike cell phones which have now moved on to under display cameras or have designed better solutions than the notch the iphone has currently, I don't believe this will be something we'll see on laptops outside of Macbooks, there is just no necessity for it there.
