Considering that Apple ditched Intel for their own Apple Silicon chips it makes more sense comparing them (for now).
When you'll be buying a new laptop, you won't be choosing between a 2018 MacBook and a 2021 MacBook, but between 2021 MacBook and offerings from Lenovo, Dell, Microsoft and others.
If you are upgrading, OS inertia may prevent you from choosing a machine that doesn't run the OS you're currently on. So a lot of Windows users may not even consider a Mac, and vice versa.
I suspect you will be able to for another year or so. See comment from me elsewhere on this thread for my reasoning.
So yes, you can compare to the current gen and would be choosing between that.
And as a friend keeps reminding me, this is their cheapest entry level processor :)
