    Is OpenCL the backbone of grand central? I have a 64 bit iMac with an ATI X1600 GPU which isn't going to be supported by Snow Leopard (OpenCL). Does any know if OpenCL is likely to be expanded to support this processor further down the line? Otherwise is there going to be any point in upgrading? Or was the several hundred(?) million transistors on my GPU not enough for the OpenCL programmers...

    No it's the other way around. Grand Central Dispatch is the backbone of OpenCL. It handles routing tasks to all compute services thus if the GPU was at full capacity Grand Central Dispatch must be smart enough to fall back to a CPU.

    I personally think we're going to see 10.6.x updates add support for more GPU. People have to realize that AMD was a bit behind the game in OpenCL as compared to Nvidia so they will lag a bit.

    Actually OpenCL and Grand Central are completely unrelated, although not mutually exclusive.
