Refreshed MacBook Air and entry-level 13" MacBook pro

I just can’t figure out which CPUs exactly Apple is using for the refreshed low-end 13" MBP. The new Air is Amber Lake-Y (back from Oct 2018) while the 4-port 13" MBPs are Coffee Lake-U from May of this year.

Apple claims it’s either a quad-core i5 (1.4/3.9 GHz) or i7 (1.7/4.5 GHz) with Iris Plus 645. I’m not aware of Intel selling anything like that.

Any ideas?
