MacBook Pro Does Not Support Both GPUs Simultaneously

Well, I've seen a Toshiba Qosmio with HybridPower switch between integrated and discrete graphics with nothing more than a short pause involved (including when you disconnect the power cable). If it is possible on Vista, why does Mac OS require a logout to achieve the same thing? Could it be, Mac OS's graphics stack is not as well written as Vista's DWM? :p

It couldn't be. :cool:

I would suspect, that the problem is related to the fact that OS-X cannot use SLI either, and likely how KEXTs are handled. Considering SLI has been around since 1998, its very negligent on Apples part to have yet to accomodate the technology.

In my humble opinion, it comes down to the simple fact that OS-X is built on Mach, which has been crticised as being one of the WORST, most inefficient kernals ever (http://en.wikipedia.org/wiki/Mach_(kernel)#Performance_problems).

speak for yourself. its about a minute for my poor old CD MBP to log in.

So that really wouldn't be pertinent to this discussion as your old MBP doesn't have both discreet and integrated graphics which require logging out to switch between.
 
The SLI is one of the feature I'm very interested. I'm looking for super portable power that can handle my 3D app (Maya) and a bit of gaming. And I keep going back to Dell's Studio XPS 13.

honestly what was the point of putting 2 GPUs into the MBP again?? I thought Ive said "nothing that doesn't need to be in there isn't!"

Apple have really messed the notebooks up. I'm not one of the "they're abandoning pros" type of people but they ARE abandoning pros.

I just don't understand some people. How do you look at the new Apple laptops and say, wow they really screwed those up?

How is that what you come to? Unbelievable..

what I'm asking is can the 9400 be used as a GPU while snow leopard uses the 9600 for non graphics tasks like transcoding or heavvy calculations in the background?

that would be the real performance boost I would be interested in.

Read about OpenCL. That's what you'll get once Snow Leopard is released.
 
Is anyone using the Snow Leopard betas noticing open cl taking advantage of the two gpus?

I follow iansilv. No updates on this?

From what Nvidia's described, it's totally in the hands of Apple - they might well do it only for hardware post-Snow Leopard, though they might, if heat issues aren't too much of a problem, do it for more recent MBPs and Mac Pros for example.
 
So there is no definitive answer? Do the Snow Leopard betas take advantage of the dual GPU setup without the logoff process?
