Does OpenCL Work With ATI Radeon HD 4670?

Some of the new iMacs have an ATI Radeon HD 4670 graphics card.

On Apple's Snow Leopard technical specifications page, they list all of the graphics card that work with OpenCL. The ATI Radeon HD 4670 isn't one of them!

What does this mean? Have Apple simply not updated the page, or do the new iMacs not support OpenCL?

iMac (21.5-inch, Late 2009), 3.06GHz, 4GB RAM, 1TB Hard Drive, Mac OS X (10.6.1), 16GB iPhone 3GS, 40GB Apple TV

The answer is not clear.

Other people (e.g., me) want to know THE answer also.
I did some poking around and it appears that AMD is working on it. Note that I wrote "it appears".

If you really want OpenCL support AND you must buy today AND you want that support guaranteed, then you must buy the $1999 iMac.

Hi,

Snow Leopard's specifications page has been updated, and shows the HD 4670 as supporting OpenCL.

Ah, well spotted. Great news.

The weird thing is: "QuickTime H.264 hardware acceleration requires a Mac with an NVIDIA 9400M graphics processor."

So, H.264 is only accelerated on the worst/lowest-performance graphics card that Apple ship?
