AMD Radeon RX M400

The AMD Radeon RX M400 is a mobile GPU released by AMD in 2016.

Why It Fails

 * 1) Poor efficiency. It uses an extreme amount of power meaning low battery life and potential to damage other components in the computer.
 * 2) It performs a lot worse than the AMD Radeon RX 400 due to having only 896 stream processors compared to the 2048 SPUs of the AMD Radeon RX 400.
