I have to tell you a something else first: There is a tech company called ElcomSoft, they make state-of-the-art tools for the computer forensics market which includes the retrieving of wifi passwords of encrypted hotspots. With the release of the latest version of this software they also released a press information stating that they managed to make their software take advantage of modern GPU's when doing its brute-force-based approach to the decryption. The state that this measurement makes getting the job done up to 100x faster. Now, you might ask what this has to do with Snow Leopard? Well, if there is ONE computing assignment whihc has nothing to do with graphics, then it is brute force decrypting of wifi passwords. And if this cool russion company manages to pull this of, I think Apple can pull this of aswell. Snow Leopard may make even 2006 low end MBP's suddenly MUCH faster than even the latest MacPro WITHOUT Snow Leopard. This would give Apple another huge advantage over Windows as MS is not even planning a comparable solution for their next OS "Windows 7". I'm really looking forward to January! Doc Edit: Only recently a new patent application by Apple was found. In this Application they stated that they managed to make somethng like a "performance-box" in which the Mac (with SNow Leopard installed) "throws in" the available performance of the CPU as well as the GPU. What this means is that third party developers won't even have to alter their apps to take advantage of the GPU because the performance is just there. So even writing a word document would "automatically" take advantage of the GPU. Edit 2: Check out the third page of this thread to see what Nvidia officials said about the possibilities: "seeing up to a 20-200x speed-up in their applications with CUDA over a CPU."
