Behind the scenes, Optimus (not) at work on new MBPs?
Update: While Engadget originally reported that Optimus was behind the MBP power-saving switch feature, AppleInsider is citing NVIDIA representatives that the feature isn't based on their tech -- they say it's home-grown by Apple. Thanks to our commenters for pointing this out.Great power is lurking inside the new MacBook Pros, just waiting to be unleashed. Along with support for up to 8GB of RAM and the heftier i5 and i7 processors, the new machines also include on-the-fly GPU switching
As was pointed out by Gizmodo back in October of 2008, the original dual-GPU MacBook Pro models (with the 9400M/9600M GT card combo) were capable of dynamic switching on the fly. The bad news was that Mac OS X hadn't "switched on" the feature, even though it did work
The good news is that now we see Apple supporting the feature in software for the newer gear -- but will it ever work its way back to the old reliables? Imagine vintage MBPs switching between the GPUs as needed, without having to log in and out. Better yet, the GPU could switch depending on state (plugged in or unplugged?) or even per application... the power management boost would be delightful.
Now that we see

Can we use the "!" button for obvious trolls like willtrade1? It's tiresome having such idiocy on the internet.

But with the new MBPs with their basic battery cycle of 8 hours or so it has a great impact i guess.

Bootcamp will always use the 9600M GT and doesnât allow Windows to access the 9400M GT at all.

I love articles like this, it helps me weed out the black sheep from my rss feed list. :)

So wait, wait. All this time I've heard about the amazing graphics switching ability, and how it increases power/decreases battery drain, and it only worked in Bootcamp? wtf
It worked fine in OS X except it required a log out and log in because the window manager process had to be restarted on the selected GPU. In Windows you didn't have to log out and back in again to use the feature.

Another poorly researched, rushed-out-the-door article from TUAW.

I believe on Windows, Optimus requires constantly downloading a whitelist of programs that would benefit from the full GPU capability. Apple might have made their own for this reason to allow it to be more automatic.
April 13 2010 at 1:17 PM Report abuse Permalink rate up rate down Replyhonestly i bet there is more to it then that. initially Apple wanted NVIDIA's optimus tech. but they didnt want exactly what you mentioned, to wait for devs to give updates and whatnot. Apple is too contoling.
but look at all the new mb, mbp, all of them now have NVIDIA cards across the board! is this a coinsidence? i doubt it, i bet that apple slipped them a fat chunk of $$$ to get the technology and have apple claim it as their own. And the fact that NVIDIA has already said its not theirs, is unlike a company. why would nvidia be so quick to comment on a competitors product without saying their tech is better or superior, whatever.
do you really think NVIDIA would let apple use gpu switching on their cards and not do anything about it?
