Power stage layoutiAs the maker publishes it, e.g. 18+2+2. The first number is the CPU core (Vcore) rail. Makers group the other rails differently, so compare the first number. Doubled or teamed stages are written as the maker prints them, such as MSI's 12+2+1 Duet Rail. A review's count of real phases goes in the source note.
