Below is an expert-level comparison of several popular ESP‑32 microcontroller variants, focusing on their CPU architectures, core counts, and peripheral sets. — 1. Original ESP‑32 CPU Architecture & Cores:The original ESP‑32 is built around a dual‑core Tensilica Xtensa LX6 processor running at up to 240 MHz. The dual‑core design is well‑suited for multitasking and parallel processing…

The ESP32-P4 has been announced by Espressive Systems with a RISC-V core and AI instructions. Powered by a dual-core RISC-V CPU running up to 400MHz, ESP32-P4 also supports single-precision FPU and AI extensions, thus providing all the necessary computational resources. In addition, ESP32-P4 integrates an LP-Core which can run up to 40MHz. This “big-little” architecture…
