I'm basing my stuff on ESP32-S3, which has an 80Mhz SPI bus. Theoretically, I should be able to drive a 240x320x16bpp display with a ST7789 driver at ~16ms (frame buffer in SRAM, DMA transfer, though that doesn't change speed but only frees up a CPU core).
For this little idiot benchmark, I used the Adafruit GFX library and respective driver. Those aren't best in class. Code here:
