Perhaps, and the reason for no review is that AMD did not supply any to reviewers. Bit of a calamity to be honest, maybe some users will do some bench marking in time.
I'm currently deciding if I want to buy the x570 I, potent M-ITX.
Unless you're using some PCiE 4.0 NVME SSD, I personally don't really see the point right now in buying an X570 board. I just hope B550 specs and release will get announced soon.
