One of the reasons OpenCL is so attractive is that it gives a general purpose solution for speeding up typical desktop operations as well :

Good question. We're only writing the closed source driver ourselves, and making use of existing closed source code in several places. We don't have any plans to make that code public in any form.
I can imagine that to clean up their driver will take many months and the driver will be slower so ati will never be able to beat the closed source driver of other companies e.g Nvidia.

I bet many parts of Ati closed driver are owned by someone else. If Ati release the code, they will be sued by several companies.
It's called middle ware, and it is a great business for Cell developers at this generation of consoles, as the PS3 is so difficult to develop for.
Middle ware solutions also had a boom with Sega Saturn, as it also had many different processors, and generally a pain to develop for.
Middle ware ease the (game) developers work.
OpenAL is an example for open source middle ware.
Unreal 3 engine is an example of closed source middle ware.

With openCL support added they can appease both preference of coding.
Didn't AMD, nVidia, Intel agree to deprecate CUDA and Close To Metal?

BTW intel is also working on their own proprietary solution as well for larabee.Last edited by deanjo; 17 June 2009, 08:13 PM.
