Even the 2400G (Ryzen 5) released around the same time as the 2200G is extremely 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 graphics).  I've done several buildworlds and more than a few poudriere runs building 1100+ ports, it never seems to break a sweat, the CPU and heat sink are still cool to the touch.
