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.

3+35Retailer pageamazon.com/dp/B0BTTZFQTPRead 15 October 2026The GIGABYTE-branded listing says Digital 3+3 VRM Design in its bullets and 3+3 Power Phase in its title. GIGABYTE's own specification page and manuals give no phase count. A 4+3 count in an unreliable review and a 5+3 count on one retailer page disagree. The board photo on this page shows six output chokes beside the CPU socket, so the phases may be doubled and no Vcore stage count is stored.

CPU core (Vcore) power stagesiPower stages on the Vcore rail. Makers call them phases or power stages. A doubled design has more stages than controller phases. Use the first number of the maker's layout, such as 14 for MSI's 14+2+1 Duet Rail. A review's different count goes in the source note.

Ryzen 8000 values are never used. The source note names the family and the other module setups. It is not the CPU's official speed. A JEDEC-only list such as 5600/4800 is not this value.
