I think for really simple stuff like Roblox it will work. It just cannot play the games with more graphics.
I bought a Ryzen 7 5700u, and it definitely can play the simple games like Minecraft and Roblox.
I saw some good youtube tests on a Ryzen 5 5500u. It seems especially good for Minecraft and the like.
Sounds great for general use. I know many people by Dell Latitudes returned from a lease with i5 version 8 or 9, and they worked great. Easy to add more ram or replace the battery if you needed all day work while unplugged.
