I don’t fully understand why are you insisting on that exact statement (that ATI/AMD “is not interested in GPGPU”) - I noticed your posts over there at GPGPU forum, and you already got proper reply there: even if the article you’re looking for exists, and even if it contains some kind of the statement that AMD/ATI was, at the moment of writing of the article, more interested in computer graphics related features of its hardware then to its usability for GPGPU work, still it would be very bold to claim ATI/AMD is not intersted in the GPGPU at all. Obviously, there is a big market for GPGPU application, and AMD/ATI is making some moves, with recent OpenCL capable releases of their SDK, to try to win at least a piece of this market; so - I’d say they are interested. The issue with them is that they’re late - NVIDIA is for almost 3 years on this market, so if you try to use their tools and hardware for GPGPU work, you’ll still encounter lots of small obstacles that are already ironed out in NVIDIA hardware and tools. Still, nobody knows what comes with the future: if they start listening what developers want, if they polish their tools, and if they start delivering hardware that is faster/cheaper/whatever than NVIDIA hardware, then certainly many among us would start to get interested in their offerings too. So - as already advised, if you’re really researching this because you’re into writing a thesis, then just skip making any kind of mumbo-jumbo marketing-derived claims, no matters what is the source of these.
