an interesting tidbit about Snow Leopard’s implementation is revealed by early tests. Though Snow Leopard doesn’t seem to enable dual GPUs or on-the-fly GPU switching for machines using the NVIDIA GeForce 9400M chipset—a limitation carried over from Leopard—it does appear that the OS can use both as OpenCL resources simultaneously. So even if you have the 9600M GT enabled on your MacBook Pro, if OpenCL code is encountered in an application, Snow Leopard can send that code to be processed by the 16 GPU cores sitting pretty much dormant in the 9400M.

—Pardon this bit of nerdery, but that is pretty damn cool
