AMD have also announced that it would add Zen 3 support for X370, B350, and A320-series chipsets*. Source
While probably not as good value as intel’s current offering for new builds – it can be good value for those on old AM4 boards.
Personally, I just updated from a 1600x to a 5600x on a AB350M Mobo.
*Assuming your Motherboard Manufacturer releases a bios update to support it.
Bought one when they dropped the price. Perfect upgrade for my R5 2600 on a B450 board.
If you are building new, Intel may offers a better value ie. 12400f
