Intel Alder Lake vs. Apple M1

Apple definitely has a habit of this. Every Apple device I've ever owned did this as well and wouldn't really ramp up the fans in full-force until they neared 100C.
I've always been deathly afraid it would fry itself, but even my old 2012 is still running after years of running at those kinds of temps. Apparently the GPUs from that era weren't as lucky (from what I hear), but the CPUs seem to have stood the test of time even in those kinds of conditions.
It's honestly almost impressive (and slightly horrifying at the same time) how close they manage to get those chips to thermal junction without frying the computer.
It’s truly precision engineering. AFAIK, Apple is the only one to pull this off, nobody else wants to invest resources into five-tuning this stuff. As o why they do it: it allows them to maximize performance while minimizing the chassis size and fan noise. Also, efficiency of the cooling system - no need to have those fans spin if they don’t do anything useful. Keeping the chips below t-junction is a waste of energy if you don’t have performance problems.
Definitely interested in a good, affordable external display. Don’t really care for any A-chips in it
not sure how that would work anyway
Of course not. The PCB and PSU is simply too large to accommodate a better cooling solution.
The M1 Mac mini is mostly empty, so you could argue there would be room for a larger heatsink and fan, no? Make a GaN PSU and it could be tiny and cool.
Look at all the **** that goes inside the Intel Mac mini. It's crammed full from the moment you pop off the bottom lid.
Nice x-ray of the M1 Mac mini for comparison.
to keep the laptop not heating anymore? especially the intel onesDefinitely interested in a good, affordable external display. Don’t really care for any A-chips in it
but we will see what that SoC means into the display
agree, if Apple wants to remove the power supply also...there can be enough room for dual M1 max...but for the rack mount-in an outside power supply like the imacs...will be a step backOf course not. The PCB and PSU is simply too large to accommodate a better cooling solution.

Yeah I’m curious to see the use case for the A-series chip is. I can imagine several, but I wonder angle Apple is going for here - like what “killer feature” Apple is going to emphasize.Definitely interested in a good, affordable external display. Don’t really care for any A-chips in it
So one thing about Apple's XDR display tech is that it should require, somewhere in the system, quite a bit of processing power dedicated just to taking the original image and converting it to a low res backlight LED image plus a high res LCD image. The two influence each other - if a given LCD pixel has RGB values set to full brightness (ie white), but the backlight zone behind it is set to 50% of the panel's current brightness setting, the pixel is actually displaying 50% gray. So you have to do a lot of math to compute what you'd like the backlight intensity image to be, then modify RGB values to correct them for the backlight zones.
I suspect that in the 14"/16" MBP and the iPad Pros with XDR, they haven't pushed that function out to the silicon which is part of the display. Among other things, it likely requires one or more buffers the size of the frame buffer. If you can avoid it, it's nice not to require your display to have that much high performance RAM - saves money, probably reduces system power, etc.
But in a standalone desktop display that's not paired to a specific Mac, they probably do want that functionality to live out in the display. No power constraints, and they probably want to sell these displays to people with Intel Macs, and possibly even let them work on Windows machines. In light of that, why not just throw a harvested A-series chip in there to do that job? It's an excellent way to use chips which have too many failures to use as a phone, tablet, or Mac.
That's my guess / prediction! We'll see what's actually real soon enough.
it’s not going to be as empty with an M1 Max or dual M1 Max SoCs in there. But you’d have to double the capacity of the cooling system for dual M1 Max, which likely means larger vents as well to move the air at the noise level Apple likes.
A single M1 Max would be fine. I'm not sure why this is suddenly about how squeezing two SoCs in the old Mac mini design.
That was the context in which Leman was talking originally that you replied to:
Note that Leman also mentioned they believed a single M1 Max would be doable. I agree with the assessment.
I think it will be doable but there might be more btw dive use instances when it won’t be able to reach optimal performance
I've just received a new desktop replacement Lenovo Legion 5i Pro with an i7-12700 mobile CPU & RTX 3070Ti. I've just completed some basic benchmarks without ramping anything up. It appears to be consuming around 185w+, not very scientific but yikes. More than 2x times the power consumption of my MacBook Pro for similar performance. Lovely device all the same.
I wonder what the Mac Pro replacement is going to look like.
Is anyone here going to get an M1 Ultra system? I have nothing that I run that would remotely come close to needing one of these. I do love how clean it is but would still prefer an iMac.

Based on how they kept talking about the unified nature of the architecture, I feel like the Mac Pro as we know it will go away and they will either make the Mini even bigger than the Studio or bring back the "trashcan" Mac design.
The rumors have the iMac Pro and Mac Pro in 2023 so I'm expecting them.
The winner is ... Luke Miani who called this perfectly yesterday.
I am not saying they wont come out, but if the only thing they are offering is PCIe slots that won't work with video cards, and the memory is not expandable nor is the CPU replaceable, what is the point of the mac pro in it's current form factor.
I'm expecting some kind of solution on RAM. I also expect a quad M1 Max chip. No idea what it would be used for but hey, it's Apple.
I am curious on the RAM solution, because that is going to be a major performance/bandwidth hit to go outside if what is on package.
