berezini :
I really want to see someone post same model comparison just to make sure there is no difference giving its assembled in CHINA.
You know what assembly is, right? That's the process where they take the CPU die, that is probably manufactured in Arizona, Oregon or Ireland (those are the only three sites that currently support 14nm Fabrication with FAB42 in Chandler being the first 450mm wafer and 7nm FAB) and they combine it with the PCB and IHS. Nothing else happens. Well probably the packaging.
Even then where those will be distributed is anyone's guess. The US might never get a Chengdu manufactured CPU.

Ryzen 5 1600/1600X and be happy with a long lasting platform.
No such thing. The platform itself will get older and you will eventually want to upgrade the motherboard. I do it with every build because there is no reason to try and keep an aging platform around a modern chip.
