We are talking about an MCU, not a CPU :)

I think once we start talking about GPU, MMU, USB, display, etc, we're getting towards a CPU of sorts.

Speaking of a low-end CPU, I want to test out the RV1103 Rockchip, those crazy little chips are running Linux apparently [1], and even able to run Python [2]. Depending on power draw, a Linux-based smart watch could be on the horizon.

Yes, we are talking MCU, it's very common now that mcu has gpu now.

For ex: Bes2700bp and bes2800 has 3d GPU iirc. Their spec is very impressive, too bad that their SDK is kind of limited to non-Chinese vendor

USB is trivial for most modern MCUs; even low-power/minimal-cost ones.

ESP32-S3 has all that minus a GPU. Runs Linux.
