Why is EVE different from other GPUs?

EVE has many differentiators when compared to GPUs, including:
No external frame buffer integrated touch screen
Simple serial MCU interfaces for controlling and implementing the display, namely SPI, Quad SPI (FT81X only) and I²C
Audio playback with built-in sound synthesizer Backlight LED PWM output
Overall an advanced architecture that provides complete GUI functionality that enables the creation of advanced graphics, while being easy to develop with.
