Advanced Micro Devices (AMD -0.35%) largely hangs its hat on a processor architecture first designed by larger rival Intel (INTC 0.64%). But things are changing fast.

AMD bought a microserver company last year that builds plenty of systems around the competing ARM Holdings (ARMH) core design. Around the same time, AMD also promised to design its own ARM-based chips. The so-called Fusion design philosophy allows AMD to mix and match processor variants without redesigning the entire chip and the system around it.

The company just published a server roadmap for 2014, showing the first in-house ARM designs in the back half of next year. This might be a game changer, but not for the obvious reasons. In the video below, Fool contributor Anders Bylund explains how the new processor blueprint opens new doors for AMD and its investors.
