Apple Silicon M1 Macs do not support eGPUs

I don't understand your argument at all. You realize Apple does put dedicated AMD GPUs in their Macbook Pros?

The Radeon Pro 5600M with 8GB of HBM2 has a pretty significant power envelope, and is coupled to 6 or 8 core Intel H series that are equally power hungry.

The fact 16" MBPs are undercooled is beyond the point. Apple ships laptops with a ~95W TDP. Why would they not ship a SoC with 16/24/32 graphics units for high-end laptops and iMacs?

Unless I'm mistaken, this isn't about the GPUs inside the MBP but about the external ones you can connect separate power and a Thunderbolt cable to.

In that case, you're not talking about a Radeon Pro 5600M but rather a desktop-class RTX 3090 with 24GB of high-performance RAM and a TDP of 350W. A MBP couldn't hope to power or cool one of those with a built-in GPU, never mind come close to matching the performance or supporting CUDA without nVidia sueing Apple out of existence.
