It has been a long time coming but we take a look at early and initial Mantle performance and a quick and rather basic initial article. The upcoming AMD Radeon 14.1 Beta driver will receive many improvements, the one most awaited being Mantle ready. At the simplest level, Mantle is an Application Programming Interface (API), or a language that game developers can use to write code that creates the graphics on your screen. In its current iteration, the Mantle API uniquely leverages the hardware in the Graphics Core Next architecture (GCN) of modern AMD Radeon. The massive advantage of Mantle is that it will free up the processor, and thus faster processors get less important as you need lesser CPU cycles.
