Recently they release ESP32P4, with very strong performance, but like you guess, without Radio
- bArray 1y agoWe 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.

- bobmcnamara 1y agoESP32-S3 has all that minus a GPU. Runs Linux.
- bArray 1y agoLooking at that now [1], seems like something I need to run a test with! [1] http://wiki.osll.ru/doku.php/etc:users:jcmvbkbc:linux-xtensa:esp32s3 http://wiki.osll.ru/doku.php/etc:users:jcmvbkbc:linux-xtensa...
- the__alchemist 1y agoUSB is trivial for most modern MCUs; even low-power/minimal-cost ones.
- mrheosuper 1y agoYes, 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
- chillingeffect 1y agoYou got downvotes but im a firmware eng and can point out more esp deficiencies. #1 completely fake FPU that they lie aboutm. #2 awful memory bandwidth. Not only slow but unpredictable. #3 small onboard memory. #4 low clock speed.
