Strix E actually has 12 phases via 6 doublers or 12 phases twinned together to make 6. cant remember which method used as higher end ASUS use twinning/Parallel set up. Actually better then B450 MSI boards but still B450 ITX has the best best up and cheaper then MSI/ASUS ATX Wifi
Strix F is useless ! E was hard to get until now
The X470 might, the B450 does not.
Look at the chart I've listed.

The op is looking at buying the Asus Rog Strix B450-E Gaming.
