Well, the bottom line is these boards are almost identically equipped, aside from the VRM configuration which is a little better on the Aorus board. And that apparently showed up a little bit in TH review testing on the B660-A in the form of some amount of throttling on the test rig which did not happen with the Aorus master. The Aorus board has a 16 phase 60A VRM setup while the ASUS board has a 13 phase VRM that seemingly they couldn't identify the amperage of in the review as it's noted with a ?, or perhaps it's that due to the throttling they are saying it wasn't capable of maintaining the amperage that was advertised. IDK which is it, but regardless, the Aorus board seems more capable and considering the customer service problems we've seen with ASUS in recent years, I think it's a no brainer that the Gigabyte is a better option on this comparison even if the differences are only minor between them on paper.
