This looks like an interesting processor and 7nm sounds great, however since the process size became mostly a marketing term, is there a comparison of Apple’s process sizes to that of GlobalFoundries and Intel?

So really you're asking for a technology comparison between TSMC, GF, and Intel.
Related to that, one should note that GF stopped pursuing 7nm. https://semiengineering.com/gf-puts-7nm-on-hold/.
