I’d like to recommend lenovo thinkbook 14 gen3 ACL.
This model has one soldered 8GB DDR4 3200MHz RAM, and one RAM slot. So this model has a maximum RAM capacity of 40GB.
Zen3 APU is the latest gen of AMD mobile processors that Qubes OS R4.1 can be installed on without workarounds.
With recent Xen, kernel and firmware upgrades, S3 suspend is now fully working.
The Ryzen Zen3 APU is both powerful and energy-efficient. It has a battery life of around 6 hours with Qubes, which is superior to Intel models. FHD web video playback is smooth, and hardly makes the fan spin when played in chromium.
To summarize the processor part, I have to say that Ryzen Zen3 offers a top-class , balanced performance. There’s no obvious shortage. To compare this processor between various options, I’ll give a form.
| CPU series | relative performance | relative battery life | additional note |
|---|---|---|---|
| Ryzen 5000s APU | average | average | can suspend |
| 11th gen core | lower | slightly shorter | can suspend |
| 12th gen H/HX | higher | much shorter | can suspend |
| 13th gen H/HX | higher | shorter | can suspend |
| 12/13th gen P/U | higher | shorter | suspend issues due to S0ix |
| Ryzen 6000s APU | slightly higher | slightly longer | needs workaround to install |
Linux driver support is excellent and comprehensive. Bluetooth in sys-audio, audio with sys-audio, audio with dom0, webcam, wifi, ethernet…are all working flawlessly. I even hear that there are places this model gets sold with linux pre-installed.
The only thing I can complain is that sys-gui-gpu isn’t working, because the iGPU needs AMD PSP to work. However, that’s a even more bleeding-edge experimental feature than sys-audio, so I’m fine with that.
