Default AMD Working on a Real GPU Dynamic Overclocking Technology

While digging through documentation for the latest version of AMD Display Library (ADL), we discovered evidence that AMD is working on a real GPU dynamic overclocking technology akin to NVIDIA's GPU Boost. Such a technology could manipulate GPU (and possibly memory) clock speeds, and voltages across multiple power states, taking into account processing load and temperatures. ADL allows third-party applications low-level interactions with AMD display drivers. Current generation Radeon graphics cards use Overdrive 5 and the feature-set it comes with, and so the new technology, along with Overdrive 6 could feature on upcoming generations of AMD GPUs.

Listed under Overdrive 6 capabilities, AMD documented three new definitions, one which indicates that a GPU's core/engine clock can be changed within a range (ADL_OD6_CAPABILITY_SCLK_CUSTOMIZATION), one that its memory clock can be changed within range (ADL_OD6_CAPABILITY_MCLK_CUSTOMIZATION), and one that monitors its activity/load (ADL_OD6_CAPABILITY_GPU_ACTIVITY_MONITOR). The three are ingredients of a dynamic OC technology in the works.
