This is a supplement to my speed comparison of STM32 and Arduino boards. Watch it here:

Details:
- 2.2" LCD display based on ILI9341 driver
- resolution 320x240, 16-bit RGB, 24-bit calculated
- 1 pass only, no antialiasing (to avoid long boring video)
- ESP8266 configured in both 80 and 160 MHz

Conclusions:
- ESP @ 80MHz is little slower than cheap STM32 @ 72MHz
- but @ 160MHz is way faster!
- ESP's SPI speed is not as impressive as STM32
