Apple plans dual graphics enhancements on future MacBook Pros
One of the advances Apple plans for future MacBook Pro models is an improvement to the handling of the notebooks' dual graphics chips, AppleInsider has learned.
Dual-graphics auto switching
More specifically, the Mac maker has up and running in its labs several next-generation MacBook Pros that can switch between their integrated and discrete graphics processors automatically, according to people familiar with the matter.
This differs from the company's existing MacBook Pro lineup, which requires users to manually toggle between an integrated Nvidia GeForce 9400M graphics core and the more powerful 9600M GT discrete processor by first making a selection in their Mac's Energy Saver system preference pane, then logging out and back in for the change to take effect (as shown below).
While those privy to Apple's plans could not say with complete certainty that the new technology would qualify for inclusion in the most immediate update to the MacBook Pro family, they do believe that's indeed the Cupertino-based company's plans. The current chipset situation Apple faces across its notebook lines also lends support to these claims.
Chipset setback
A year and a half ago, Apple made a radical decision to jettison Intel's supporting chipsets from its MacBook line in favor of cutting-edge chipset technology from Nvidia, one which works to support the systems' primary Intel CPU while bundling a GeForce 9400M integrated graphics processor supporting better battery life and up to five times faster graphics performance. MacBook Pros received similar treatment, with the addition of a secondary, more powerful Nvidia GeForce 9600M GT discrete graphics processor for higher performance operations.
The move threatened Intel's chipset business, prompting the chip maker to refuse Nvidia a licensing extension to develop rival chipsets for its latest-generation Nehalem architecture. Nehalem embodies the new Core i5 and Core i7 processors Apple and the broader industry are widely expected to use (1, 2) to power their forthcoming notebook refreshes, thereby requiring PC manufacturers like Apple to once again rely on proprietary Intel chipsets and their integrated graphics processors.
For its part, Nvidia disputed Intel's claim, saying it believed its license with Intel extended to the Nehalem architecture. In an effort to hold its ground, Intel took the matter to the courts, filing a lawsuit against the graphics chip maker to halt its development of compatible chipsets for Nehalem and future Intel architectures. These actions caused the U.S. Federal Trade Commission to step in last December with a lawsuit of its own against Intel, accusing the company of using its leverage in the market to stifle competition.
The ongoing high-tech spat has brought Nvidia's fledgeling chipset business to screeching halt, hindering Apple's future notebook designs in the process, according to people familiar with the matter. They say these unexpected complications may be a cause of blame for the aging status of the existing MacBook Pro line, which hasn't seen a significant update in over 16 months -- well beyond its average.
Still, Nvidia hasn't been standing idle and as recently as this month introduced a new technology called Optimus [white paper PDF] to help secure its footprint in notebook designs across the industry. It's also strikingly similar to the description of the technology said to be making its way into next-generation MacBook Pros, which, given Apple's tight relationship with Nvidia, appears to be a bit more than a coincidence.
Specifically, Optimus was designed to work alongside Nehalem notebook designs that include an integrated Intel graphics processor in addition to a discrete Nvidia graphics chip, choosing the best of the two graphics processors for running a given application and automatically routing the workload to either the discrete Nvidia chip or Intel integrated graphics core to deliver the best performance while also providing optimal battery life.
"Just as a Hybrid car chooses between the gas-powered and electric car engine on-the-fly and uses the most appropriate engine, Nvidia Optimus technology does the same thing for graphics processors," Nvidia explains. "Optimus Technology instantly directs the workload through the most efficient processor for the job, extending battery life by up to 2 times compared to similarly configured systems equipped with discrete graphics processors."

Comments
How does Intel's latest chipsets and their integrated graphics processors compare to nvidia's? If Apple has to release Macbook Pro's with Intel's graphics chips, is this a step backwards?
they suck and yes
If Intel wanted to snuff Nvidia, they should have bought them like AMD bought ATI.
Guess they figured they just could move right in and not meet any resistance. I'm glad Intel is being sued by the Feds.
We need separate GPU's.
I just wish they'd hurry the heck up and get the new i5/i7 Arrandale MBP's out soon... selling the current models with Core 2 Duo at those prices is criminal. C'mon Apple, put the "Pro" back in MacBook Pro!
Read the article. Apple can't just stick a Core i5 or i7 into a MacBook with the same chipset. Due to Intel being greedy bastards, Apple are being forced to use Intel's own chipset, which only has Intel integrated graphics. This means that they can't get decent graphics performance on machines without enough physical space for a dedicated GPU. That was the marvels of the Nvidia chipset, the 9400m gives good graphical performance on an integrated GPU, where the Intel integrated graphics have bad performance.
With Apple's move toward GPU computing, i.e. OpenCL, all their computers need to have a GPU that has at least some amount of processing power. Otherwise they may as well scrap OpenCL and use the CPU. The integrated Intel GPUs lack any decent amount of processing power (and most likely don't support OpenCL anyway), which is why Apple is in a bit of a pickle.
So, even if Apple does switch to the Intel chipset and put a Core i5/i7 in their MacBooks and Mac minis, the graphics performance will be worse than with the Core 2 Duo and 9400m.
After Nvidia's zero concern with Apple after the MacBook issue, I say dump them and go for ATI
That's sort of the way I feel too. But the new optimus stuff from NVIDIA looks pretty nice...if it works as advertised.
AFAIK, ATI doesn't offer anything comparable to this.

I'm not sure what ATIs mobile CPUs are like, but their desktop ones run extremely hot, which is perhaps why Apple's not using them in their portables.

You're telling me things I already know buddy... I've read nearly every page of the entire "waiting for Arrandale" thread over at macrumors. Read the thread... its got 6000+ comments. We've explored virtually every nuance of the Intel/ Nvidia dilemma (months ago)... and we're patiently waiting for an i5/i7 Arrandale MBP along with a discrete gpu. Yes, the Intel IGP is wimpy, but people seem to forget that Apple can still put whatever discrete gpu they want into the MacBook Pro... and Nvidia's Optimus tech is a likely candidate.
These companies seriously need to stop messing around and actually work like a team. Customers will suffer because some two companies don't agree with each other. Hopefully the whole i3/i5/i7 processor/GPU situation gets resolved. The Macbook Pros lineup could be in serious trouble if it doesn't.
I don't see this as a popular solution. As a matter of fact I think it's stupid. Why have two chips when they can just have one and throttle it up or down as needed just like a regular CPU?
Was thinking about that too.

Intel integrated graphics suck (I have a couple low end WinPCs and the wifes beater notebook that use intel Integrated.).
I think the the Intel Integrated + Discrete GPU has a great deal of promise, especially with the things I've read about off loading CPU processes to GPU's in OS.X.
Think about it. For intense graphics, OS.X could auto swap to a real GPU, and off load some processing tasks to the intel GPU, functionally boosting both the CPU performance and the Graphics performance.
Now, battery life would suffer. But if done correctly, it could make games, rendering, whatever scream.

The problem is the integrated GPU attached to the CPU in Arrandale. It's highly likely that to use these new chips, to get the performance of a high-end performance GPU you need to have it as a second chip alongside the integrated graphics. This switching tech makes it seamless to switch between the two behind the scenes. As I understand it.
