Do these intel igfx actually support open cl? If they don't I wonder what apple will do to work around this. Because I don't think they do, and what is the point in bringing on a new tec in snow leopard if the hardware doesn't support it...
Although I don't know for sure, I would guess that Intel graphics does not support OpenCL, or anything fancy, really. However, I would suggest that this is completely irrelevant, because Apple will almost certainly pair discrete graphics solutions to all of its notebooks.
Apple already has a 9400M in all their notebooks, and they can't go backwards. So the no-good-GPU models that had the single 9400 get something better (AMD 4300ish, maybe 4500ish?), where as the decent-GPU models get a 4600ish. (Hopefully equivalent 5X00's, but that seems unlikely)
These cards I expect will be used either completely bypassing the Intel GPU (disabling it might save a couple more watts), or switch between them as high/low performance modes like the present decent-GPU systems. I'm leaning towards the former.
Which will of course mean all systems will happily support OpenCL
BTW, the 9600 is rubbish, you can't deny it. That doesn't make the entire computer rubbish (obviously), but it does severely cripple it in games, and now with OpenCL, will start crippling it in many more areas too. Basically, it makes a potentially fantastic, all-round computer only a great, does-almost anything computer for most users. And makes a potentially 1337 computer get totally pwned, dude, for gamers.
