According to AMD testing most of AB functionality works and the only locked/missing thing is voltage control/monitoring feature. Which effectively means that majority of overclocking/monitoring software supporting RX 6x00 series cards will start working with 79xx out of box. Anyway, just like NVIDIA's 40x0 was happliy backward compatible from NVAPI side with 30x0 series (which means it didn't require major software updates to got it working with new GPU architecture), new AMD GPUs also seem to be backward compatible on ADL API side with the previous RX 6x00 series cards. Working on providing software support on day one is a nice thing and definitively right way to go so I can only welcome it. Got contacted by part of AMD SW team on MSI AB compatibility with upcoming GPU family, they want to ensure compatibility prior to product launch. Previously AMD were not too focused on ironing compatibility with third party software products unlike green vendor, but this time they pleasantly surprized me. AMD Radeon 7900 launch day is approaching.
