It’ s better to run kernel at least 4.10 according to this material for Ryzen.

Yeah you really need to be running a recent kernel (regardless at least for security updates, this redhat ancient kernel crap at work bugs me, a lot) for proper recent CPU/GPU support.
Here is small comparison AMD Epyc 7601 vs Intel Xeon Scalable Platinum 8180M:

For me AMD new processors looks great and have awesome price (compared to Intel). What do you think about it? Did I missed something (if so let me know and I will update my post)?
btw. Looks like tables does not work on this forum.

I haven’t upgraded us to 1.9 yet… I’m waiting for CentOS 7.4 to come out with OverlayFS support (Discourse now requires it
