Comparing memory interface vs PCIe isn't valid. Comparing LPDDR5 vs DDR5 latency, throughput, and power consumption would be good.

In this case I'd argue it is, because to communicate between the CPU and GPU on a non-SoC computer, you need to send that data through the PCIe interface. On the M1 SoC, you don't. They operate differently, and thats the main point here. You have to add those extra comparison points.

yep, thats definitely true
but it would be nice if the soc itself would be a module that you could upgrade and keep the case/display, it would also cut down on environmental impact probably as well...
Because that degrades the performance overall. SoC has proven itself to simply be more performant than a fully hotswappable architecture. Look at the GPU improvements they're mentioning - PCIe 5.0 (yet unreleased) maxes out at 128GB/s, whereas the SoC Apple has announced today is transferring between the CPU/GPU at 400GB/s.
In the end, performance will always trump interchangability for mobile devices.
