If these cpus are as good as the rumours say I can see sales of them being huge.
MSI are saying they're not going to support R3 on their 100-series and 200-series boards.
TPU say "Zen 2 processors have steeper electrical requirements that 300-series motherboards don't meet", I'm guessing that's a typo and they meant to say 100-series and 200-series.
The current MSI 400 series boards on average have the best VRM and VRM cooling setups especially at the lower end and midrange levels.
Well i was looking at getting a higher end MSI board, not anymore...
But their M.2 shields make the M.2 devices' temperatures worse.
Buildzoid,Gamersnexus and Hardware Unboxed have looked at quite a few of the lower end and midrange B450 boards,and the MSI boards have the best implemented designs and the best VRM cooling.
A fair number of the Asus and Gigabyte,have terrible VRM cooling and just double stuff up to give the impression of better VRMs than they actually have, and kind of don't indicate doubling is happening. It ends up with the VRMs running very hot.
When it comes to ATX and mATX Ryzen 400 boards,I would tend to go for MSI,and some of the ASRock models.
