ESP32 to 8266 Comparison:
The ESP32 features a powerful 32-bit dual-core processor with a clock speed ranging from 160MHz to 240MHz, while the ESP8266 operates with a single-core CPU clocking at approximately 80MHz.
Due to its higher speed, the ESP32 consumes more power than the ESP8266.
ESP32 offers over 16 GPIO pins, along with UART, I2C, I2S, ADC, DAC, and TWAI pins, whereas the ESP8266 provides 16 General Purpose Input Output (GPIO) Pins and additional GPIO, UART, I2C, I2S, and ADC Pins.
ESP32 includes both Bluetooth and Wi-Fi capabilities on board, while ESP8266 supports only Wi-Fi.
