I think there isn't any value giving full details. It's just marketing. I'd rather know max spec & heat dissipation - then you could determine if the VRM is over sized or undersized relative to competition.

All that matters with VRM is that it provides enough clean power...

You could use 1 phase or 30 phases I don't care if you accomplish the goal of providing good clean power.

Example if you could pick between the two following boards:

Option 1: 4 Phase 400A SPEC/ Big Caps /Big Mosfets/ Great cooling
Option 2: 8 Phase 250A Spec/ Cheap caps/ cheap mosfets/ no cooling

Which option would be a more robust platform? If you change the amount of switches or phases it doesnt change the specs at all.
