To give you an idea of the complexity of these specifications, they only cover the first two steps, initialization and primitive 2D, and yet they add up to just shy of 900 pages. Amazingly, these are (as far as we know) AMD's own internal documents and not new documents created/censored for public use, which is one of the factors that have convinced us about how serious AMD is about their efforts. Releasing the rest of the specs required to build a fully functional driver will expose information that isn't usually public, such as details of the Ringbus memory controller, the UVD video decoder, the programmable anti-aliasing processor, latencies, texture compression, and basically everything else needed to identify the strengths and weaknesses of their chips along with some idea of how AMD goes about implementing all of the major features in those chips. Even though the specifications to their chips won't be anywhere near enough to duplicate the chips, it is a start for anyone that needed some "inspiration." The GPU development cycle is still short enough that it's plausible that someone could steal AMD's technology and implement it before it is outdated; where someone doesn't have to be only NVIDIA.
