When snow leopard finally comes out will the 9400M be able to take advantage of open CL, even if only minimally? Or will it not do anything really since its an integrated chip?
Got a tip for us?

9400M And Open CL?

Lol, thats for sure haha.
-I read on another post though, that the 9400m isn't a good chip because its not open CL compatible. I just want to know if this is true or not.
The person who stated this was comparing a stock imac with the 9400 to an imac with a GT120, and he said that just for future proofing, even though the buyer wasn't a gamer or anything, that he should get the GT120, simply because the 9400 wont work with open CL.
Well, it can do CUDA.
OpenCL isn't mentioned on their site for it

Ars Technica says the chip is OpenCL ready =

As Nvidia says:
"OpenCL™ (Open Computing Language) is a new heterogeneous computing environment, that runs on the CUDA architecture."

Thats what I thought, but I just wanted to make sure.
Now obviously the 9400 isn't a very powerful GPU, but it with SL, we should notice a decent performance boost right? And of course the faster the GPU, the better?
You won't just automatically notice a difference the only way you will notice a difference is if the Program is Programmed to run using the OPEN CL architecture. Otherwise there will be absolutely no difference.
Yes I was 100% aware of this. I suppose as more programs come out and are re-written, companies will begin to take advantage of these new technologies.
Or CUDA.
Don't forget Apple's sat on this. They could have refactored some or much of their code. They could drop updates of OpenCL integrated OS apps as the OS develops after release.
+1
Plus, don't discount what the 9400m is capable of. It's no top of the line card by any stretch but quite brilliant for what it is.
"Nvidia said that its OpenCL 1.0 drivers will support all GPUs based on the CUDA architecture."
So that's a yes then. (Quote from http://www.tgdaily.com/content/view/42422/140/)
Very tue, but at least it's capable of Open CL and will do the trick when needed.
We're in agreement.
I've been really pleased with the 9400m. My room mate and I play L4D and it always amazes him how well it runs on my laptop in comparison to his desktop (He has a GTX 295 in his PC). I wanna get a CUDA enabled card for my SETI box.
