As late as even a couple weeks or even a week ago people may have bought Gigabit Ethernet (550/667MHz) PowerBook G4s. Less than a week ago, Apple introduced the DVI (667/800MHz) PowerBook G4s. The older (Gigabit Ethernet) (550/667) PowerBooks included an 4x AGP ATi RADEON Mobility 16MB DDR graphics chipset.

Now, here's the controversy:
http://www.apple.com/macosx/newversion/

Jaguar dramatically improves the performance of Mac OS X with Quartz Extreme. Jaguar lets Quartz offload compositing tasks to a supported* video card, using OpenGL to accelerate the drawing and compositing of graphics. As with the benefits 3D games get from a video co-processor, the main CPU chip(s) can then focus on application-specific needs.
That means your shadows will drop quickly, your genies will appear slicker and your transparencies will layer faster � and Mac OS X can do more processing in the background while you move the foreground.
*nVidia: GeForce2MX, GeForce3, GeForce4 Ti, GeForce4 or GeForce4MX. ATI: any AGP Radeon card. 32MB VRAM recommended for optimum performance.
VERSUS

Jobs being quoted as saying 32MBs and 2x AGP are required. - According to MacCentral

Which do you think is true? Will the Gigabit Ethernet PowerBook G4s have Quartz Extreme or no?

Do you really want this on a Powerbook? On my revB 667PB the very loud fan goes on as soon as I use an OpenGL game. How much will extreme aqua be using the gpu? enough to turn the heavy fan on?

I personally want as much speed as possible on my 550 since Mac OS X defintly needs some improvments in this area.

true, me too. I am just scared by the fan. As games use the cpu at 100%, no wonder the fan goes on. But will the intensive usage of the graphic card alone generate too much heat?

I think it will work, someone should call an apple store and see what they know.

Remember, the Stevenotes just serve to summarize things. I would trust the official written word over a brief sentence in the Stevenote.

Agreed.

Steve has made several mistakes in his keynotes before. Don't sweat it.

It's just odd because the RADEON in the Gigabit Ethernet PowerBook G4s is the only RADEON with less than 32megs.

I definitely hope that it'll work, my TiBook is only 5 months old. One good thing is that offloading the load to the CPU would probably make the fan come on less often, since a lot of the load is taken off of the CPU, which is a major heat producer. Just like how the Radeon takes the load off the CPU for DVD playback and therefore increases battery life, I'd imagine power and heat savings for QE as well.

let's put this in perspective- the Gigabit (550/667) owners will be better off than any iBook owner you have the Radeon and 16MB, so half of the recommended...... iBook has the Rage 128 which is not supported and only 8. i know this is not apples to apples and oranges to oranges but be glad for what u got!

The web page says recommended for optimum performance, not required in order for it function at all. Looking at the wording I expect it to work in some circumstances e.g. on a single display, either the built-in TFT or an external display with the lid closed. It's a matter of available VRAM to manage the effects. It may be possible for it to work with some level of monitor spanning, lowish resolution, thousands of colours.
