These measurements are irrelevant to the question at hand, as they toggle the pins in software. If you were using them in a communication setting, you would use pins that can do serial communication using DMA, consult the processor datasheet for details. It looks like adafruit is able to push pixel data at 80Mb/s (that's Mb, not MiB) over SPI to a display: https://learn.adafruit.com/adafruit-pitft-28-inch-resistive-touchscreen-display-raspberry-pi/faq#faq-3 https://learn.adafruit.com/adafruit-pitft-28-inch-resistive-...
