> performance will be 1/3 of the M1 air

I run an old (I think maybe 4 or 5 years) thinkpad with 64GB RAM. I see often these claims of superior performance of new macs, and it leaves me scratching my head. I do not have (almost) any workflows where the performance is not sufficient. For the ones where performance is not sufficient, I am happy to turn on my desktop. So my question is, what are the workflows people have benefit from the superior performance of new macs and at the same time do not justify working on a beefy desktop?
