eGPU with an Apple accelerator with a bunch or RAM and GPU cores could be really interesting honestly. I’m pretty sure they are capable of designing something very competitive especially in terms of performance per watt.

Really, that’s a place for the MacPro: slide in SoC with ram modules / blades. Put 4, 8, 16 Ultra chips in one machine.

You honestly don’t need extra CPUs in this system at some point do you?

They are inseparable for Apple. CPUS/GPUs/memory. They can use chipsets to tweak ratios, but I doubt they will change the underlying module format—everything together.

My suggestion is to accept that format and just provide a way to network them at a low level via pci or better.
