There is a frustrating amount of trial, and failure involved designing power circuits for very low voltage, but power hungry chips like CPUs, GPUs, and such.
Even people buying reference designs often trip with capacitor selection, and such.
I believe, it should be universal now that for <1V chips, last stage voltage regulation needs to be on-package, and fully managed by the chip itself, omitting any firmware/software from the loop.
