What Mantle does
Mantle is the harmony of three essential ingredients:
A driver within the AMD Catalyst™ software suite that lets applications speak directly to the Graphics Core Next architecture;
A GPU or APU enabled with the Graphics Core Next architecture;
An application or game written to take advantage of Mantle.
Mantle reduces the CPU’s workload by giving developers a way to talk to the GPU directly with much less translation. With less work for the CPU to do, programmers can squeeze much more performance from a system, delivering the greatest benefits in gaming systems where the CPU can be the bottleneck.
