Yesterday, AMD unveiled its SDK Open CL, only available for Linux and Windows. It is likely that the one dedicated to MAc OS X will be available when Apple will release MAc OS X 10.6.2 as it should massively improve drivers for Radeon. It is rather enjoyable to see both graphic card manufacturers to work hard and fixing problems on Open CL, a key feature of Snow Leopard. When looking into the new SDK, there are references to a Radeon HD 5900, so far unknown as officially the flagship model is the Radeon HD 5870. AMD is most likely waiting for NVIDIA to release its new models before unveiling a potentially even faster unit.
PS: During years, graphic cards dedicated to our Mac have always been one generation away, and Apple never considered that one could play games on a Mac. things will change with Open CL and Apple will have to invest more resources to offer more powerful graphic card models as well optimized drivers.
