Looking at a handful of benchmarks it was the fastest single core.
Looking at a lot of other benchmarks, chess, …, it was was not the fastest single core.
Curious. What kind of single core chess benchmark results are you seeing?

Intel needs to fix lots of things, especially their power hungry performance. It's hurting them in the long run. Also, AMD is using TSMC for GPUs. Not sure who their CPU fab is.
If you have enough money for the watt usage, than that’s not a problem for many people.

It's actually doable without the laptop looking like this.

Intel's Alder Lake laptop chips can actually boost to 157w. This is double the max power usage of the M1 Max (100% CPU + GPU). If Apple allows the 16" Macbook Pro to get hotter and they throttle the M1 Ultra when the user does heavy CPU + GPU work at the same time, Apple can do this now.

The upside would be that you can get a 20-core CPU performance or 64-core GPU performance in a laptop as thin as the 16" Macbook Pro. This would be true as long as you don't max the CPU and GPU at the same time.
There wouldn't be too much of a benefit because you wouldn't be seeing 20/64 Ultra-MacStudio performance numbers from a laptop that throttles under load; you'd get that performance briefly until; it gets hot and then the performance would drop. Battery life would also take a big hit; not to mention the Ultra's heatsink itself weighs over one pound more than the Max's so this Ultra MBP would be thick, heavy, loud, hot to the touch, and have miserable battery life when pushing it.

A Macbook Pro 16" should be able to power a 20-core M1 CPU at 100% without throttling.

Anyone buying an M1 Ultra Macbook Pro would be buying it as a mobile workstation. They won't be expecting excellent battery life.

Anyways, all hypothetical.

I can get the 10/16 M1-Pro to throttle in my 16"; throttling an M1-Ultra would be a piece of cake.

M1 Max CPU runs at max ~35w CPU. M1 Max is able to run at 92w+ sustained.

Thus, you can run an M1 Ultra CPU on a 16" Macbook Pro at full power.

Would Apple ever do it? Most likely not.

They wont do it because Apple knows that the current 16" MBP can't sufficiently cool the M1-Ultra which means throttling would eliminate a lot of the Ultra's extra performance. The MBP would need larger fans and a two pound heavier copper heatsink to stop it from throttling.

Use it for demanding tasks like 3D rendering; once the temps hit ~90C it throttles.

How much performance degradation you experience and after what time interval? I am asking since I never observed throttling behaviour on my M1 Max (16"). The CPU/GPU frequency for me is always at nominal levels, regardless the temperature.

That will be great.
Do we have at least one AAA-Game which needs 64 GPU cores at max and also using in the same time all 20!! cores at max???
If not then there is really no problem to have M1 Ultra inside the MacBook Pro.

On my M1-Pro, when rendering several high res images or a video I can get shorter times if I force the fans on Max speed to keep the temps down. If I do a lot of batch processing in LightRoom I can also get the temps up and fans on. I would image that if I did 3D a lot then I could make the M1-Max also throttle as well. Considering the MBPs are not set up to cool the Ultra I would image it would easy to throttle it there as opposed to the Ultra in the Studio which has much better cooling.

In this case, when it comes to a laptop usage, power comes down to hours of usage. This isn't about how expensive it is to run an Intel CPU. It's how long you can run it detached from the outlet, after all that's the main intention of running a laptop.

While I don't question Srouji's skills, Apple has been hiring a lot of top talent in the field. I don't think a single person changing employers would make or break Apple's track record.
look what Steve Jobs did with Apple since his return...and yes Steve it was just one person
One person mind can affect in the good way thousands ...the vision and knowledge is the most important thing
Again if the big mind is leaving...is not that the remaining people cannot continue the momentum, its about what this man can do to the next company...Look what Intel become after he left...Amd took over and Apple...making Intel a 3d silicon company
Apple was a mediocre in SoC until this man arrival...he was the first to make the 64bit mobile SoC thinking almost 7-10 years ahead to apply this to the mac

He lives in Egypt and is using the MacBook Pro 16-inch at full speed overclocked in the sun…
My God...i tried that one time in Dubai...directly in the sun where the temp under the sun was around 57C
The road was melting beneath me
