All the previous answers are good answers. A used ThinkPad X230 or T430 with 16GB RAM and an SSD is certainly an excellent choice.
You have however expressed the wish to have an AMD based computer. The following machines appear to be worth a look:
- Lenovo ThinkBook 14 G2 ARE
- Lenovo Ideapad Gaming 3
- Asus ROG Zephyrus G14 GA401IV-HA112R 14”
- Acer Nitro 5 AN515-45
- GPD Win Max 2021
The two Lenovo’s seem to pretty much work out of the box. The Asus has suspend issues and the Acer and GDP require some more troubleshooting (as outlined by the reporters).
Between those 5 you should find something that fits your needs. Good luck!
