AMD Asynchronous Compute Engines Improve DirectX 12 Performance

AMD claims that its Graphics Core Next based GPUs improve DirectX 12 performance by up to 46% by leveraging the Asynchronous Compute Engines (ACE) built into the architecture. The ACE units take advantage of the thousands of stream processors found on the GPU through the use of Asynchronous Shaders. Proper multi-threading support wasn't available in DirectX 11 as the amount of complexity involved was high and the necessary hardware was unavailable. The use of Asynchronous Shaders "allows for tasks to be simultaneously processed independently of one another." In order to take full advantage of the Shaders, the GPU must be designed with the support in mind, and the ACE units on AMD GPUs fulfill this purpose. In a LiquidVR demo with post-processing enabled, 158 FPS were obtained with Shaders disabled and 230 FPS when enabled, an increase of 46%.
