Sounds nice. I'm currently fine-tuning my Lenovo IdeaPad Flex 5 (to run Linux on it) and it's quite the sweet package already. Considering IdeaPads are lower range ThinkPads, I can see those being quite successful.
The Ryzen 5 4500U is a little firecracker, and surprisingly good in games : I booted Tomb Raider 2013 (Linux port) on it, and ran the benchmark in Ultra mode 1080p - results were a bit lower than my old Radeon R7 270, but not by much.
Meaning that YES, you can game on these APUs!
