Apple uses its own unique automated graphics switching technology to allow these higher-performance MacBook Pro models to switch between these integrated graphics chips and the more powerful discrete graphics processors from AMD.
Apple owns and developed the switchable graphics tech,on their laptops, using AMD gpu's.

I never payed much attention to Apple's notebooks but they have been using nVidia GPUs for quite a while now in the Macbook Pro line so I was a bit surprised to see AMD graphics in a Apple notebook.Apple flip-flops regularly. You could ask the same thing when they switched from discrete AMD GPUs to discrete NV GPUs and get the same answer: *crickets*.
The best guess you're going to get is that now that Apple doesn't use NV IGPs, they don't need to worry about the entire laptop graphics stack being similar. In that case AMD normally has the edge on performance-per-watt, although the entire concept becomes murky with oddly clocked & binned laptop parts.
Apple has definitely been on the forefront of novel GPU uses, even if the hardware they use isn't the latest generation. They were the first to use a GPU accelerated desktop, and they were the first to ship with OpenCL. To date though, they have done next to nothing with OpenCL, which raises the question of whether they have something planned in the long term. If they do - and if they need strong OpenCL performance for whatever they're planning - then an APU is a distinct possibility. However without performance data on Llano (they don't do netbooks and hence will not use Brazos/Zacate), it's hard to say what Apple may do.I never payed much attention to Apple's notebooks but they have been using nVidia GPUs for quite a while now in the Macbook Pro line so I was a bit surprised to see AMD graphics in a Apple notebook.
Do you guys think they may consider APUs in the future?
^ this nvida card where overheating killing laptops.Perhaps due to the nVidia recall on previous Macbook Pros (plus all the other laptops)?
Yes, once their powerfull enough, I think APUs or even just Intels IGP, will push dedicated cards out of laptops. Its a more power effecient design, and its cheaper, which is good for notebooks/netbooks.... unless your the type that buys alienware laptops for like 20,000$.Do you guys think they may consider APUs in the future?
I read this story and thought of this thread, it seems Macbook pro's are having major problems, and the quick dirty fix is to disable the AMD gpu .

It looks like Apple responded with a possible software fix.
Apple releases OS X 10.6.7 with fix for MacBook Pro display issues
Except the problem was probably with the driver of the gpu, and not the switching tech, if disabling the Radeon gpu , solved the constant freezes. But believe what you likeYup, looks like Apple fixed the problem they had made with their own switching tech (as you pointed out in post #8), so now the AMD GPUs should work properly as Apple, assuming they don't have a design flaw that causes them to fail like the NV GPUs they used to use.

Apple releases OS X 10.6.7 with fix for MacBook Pro display issues
Its a software issue... so either AMD or APPLE, has some kinks to work out to get it working.While Apple isn't offering much publicly at the moment, a user that spoke with customer service said that Apple seemed to be aware of the issue, and that they suggested it was a firmware or driver-related problem, and not an actual hardware issue. Unfortunately, there's still no indication as to when it might be fixed.

Before reading below please update to the newly released 10.6.7 update available from Apple. (http://support.apple.com/kb/DL1363)
How to fix this issue entirely: It's now confirmed by multiple testimonies, on Apple's discussions forums, that 10.6.7 does solve this issue entirely. Tests has been done using the various scenarios described below as well as using high demanding benchmarking software like SmallUXGPU, and nobody has been able to reproduce the issue since 10.6.7. Good work Apple!
So update to 10.6.7 and problem solved!![]()
