A620 motherboards
A620 is AMD's entry AM5 chipset: no CPU overclocking, PCIe 4.0 throughout, and the smallest VRMs on the platform, aimed at processors in the 65 W class.

- The thing people get wrong
- A620 boards will happily accept a Ryzen 9, and this is where most AM5 throttling happens. A 65 W or 105 W processor is fine; a 170 W one is not, whatever the compatibility list says.
The spread inside A620
Inside this one chipset, the ASRock A620M-HDV/M.2 holds about 175 W of sustained core power and the ASUS TUF Gaming A620M-Plus WiFi holds about 365 W. That is a factor of 2.1 between two boards wearing the same badge, and it is the reason a chipset name is a poor proxy for whether your processor will keep its clocks.
The same processors on the best and worst A620 board
Sorted worst verdict first, so the pairings to avoid are at the top.
