[PLUG] How do AMD Ryzen 2nd gen processors/boards go with Linux

[Ravishankar Rajagopalan]

Hi All,

I've been using Ubuntu 14.04LTS on an Intel processor for many years. I 
am now looking at building a new machine for software development this 
time using an AMD processor instead of Intel - as it looked like cost 
effective and yet powerful enough.

I am thinking of using a AMD Ryzen 2nd Generation Processor (mostly AMD 
Ryzen 7 2700X or a AMD Ryzen 5 2600X) and an X470 based motherboard 
(Gigabyte X470 Aorus Gaming [but not the Wifi version as it's too 
expensive and I don't need the on board Wifi] - based on 
https://www.techradar.com/news/computing-components/motherboards/best-motherboard-14-reviewed-and-rated-904229 
or MSI X470 Gaming M7 AC Motherboard)

Does anyone have experience using this combination or any other AMD 
Ryzen 2nd generation systems for software development use? Just wanted 
to know if it's OK to go ahead since it's a considerable investment OR 
is it safer to stick with Intel based systems? If you have any 
recommendations for motherboard-processor that would be great too. Had a 
cursory glance at some websites talked about some GCC issues with 1st 
gen Ryzen processors. Also one dealer told me that using the newer AMD 
processors one needs to install Ubuntu 18, and it won't work with older 
Ubuntu versions, any idea how true is this?

Would appreciate an early response. If anyone has experience/knows of 
other people's experiences building AMD 2nd gen Ryzen systems using 
Linux, kindly share as I plan to order soon.

Thanking in anticipation.

Ravi
