Yes, it works well.

There are no obvious MOSFETs visible in the picture, and determining their condition goes beyond just checking them in an image. I can note that the heatsinks appear quite small. The boards themselves aren’t up to the same standard. B550-F is clearly better than X570 Elite, which in turn is superior to X570 Gaming Edge.
we're unsure about the power stages involved, but it seems likely they're using basic discrete mosfets. caps and bulky components like inductors aren't actually mosfets and are hard to see. the best way to confirm is to take out the heatsink and inspect directly. we might find some videos or references that discuss this. it's probably not what we expect, though.
It's hard to tell without seeing it, but from the size I guess it's a lower spec—maybe around 5+3, not close to the Aorus Elite's 8+5.
