Even the 2400G (Ryzen 5) released around the same time as the 2200G is extre=
mely stable for me (13-current), except for DRM (for which I have to use the=
VESA radeonkms driver as the amdgpu doesn't yet seem to support the 2400G g=
raphics). I've done several buildworlds and more than a few poudriere runs b=
uilding 1100+ ports, it never seems to break a sweat, the CPU and heat sink a=
re still cool to the touch.
