The document compares the IMX6 Quad and APQ8016 processors. The IMX6 Quad has a wider operating temperature, more connectivity interfaces, more GPIO pins, and more free open source support online. However, it has poorer CPU and graphics performance, larger board size, and overheating issues. The APQ8016 has smaller size, higher performance CPU and graphics, lower idle power consumption, and built-in wireless, but only one USB port, no Ethernet, and less connectivity and customization options than the IMX6 Quad.
