I'm currently running the Ryzen 5 4500U with Fedora 32 + rawhide kernel, and strongly recommend anyone using a Zen2 APU under Linux to upgrade to the 5.8RC5 kernel. There are some tremendous performance and battery life gains over the 5.4 kernel that's current in Ubuntu 20.04 and even the 5.7 kernel that the OP is running.
