Thanks to the new video card, the iBook also enters the Quartz Extreme "club". This is one of the good news related to the release of the update, which took place today, of the low-end laptop.
The new laptop, in fact, now adopts a Radeon Mobility, one of the cards that Apple requires to use the new desktop video acceleration system announced in recent days and included in Jaguar, the next version of Mac OS X still under development .
As known, in fact, and as clarified in a very precise way by Apple, the minimum requirement of Quartz Extreme to entrust the rendering of the desktop to the OpenGL graphics engine and to the 3D graphics card, downloading the processor from heavy tasks such as drawing windows and animations, the availability of a latest generation card. As for Nvidia, the GeForce2MX, or a GeForce3, GeForce4 Ti, GeForce4 or the more recent GeForce4MX. Among the ATIs, all Radeon Radeon AGPs, such as the one (albeit in the mobility version) used by the iBook
The adoption of Radeon on the low-end laptop makes it "complete" in the club of machines that are able to take advantage of Quartz Extreme. The entire range of Apple desktops, from eMac up to G4 dual GHz, have been using cards or Radeon or GeForce4 for a few months now; now with the arrival of the new generation iBook we can say the same thing about laptops.
The only handicap of the iBook in the comparison of the rest of the range is the 16 MB of video Ram instead of the 32 recommended for optimal performance. This could make it less agile than all other Apple desktops and laptops that now (including eMac) have cards with 32 MB of video memory, but in any case enables it to use Quartz Extreme.
For the avoidance of misunderstandings and inaccuracies that continue to circulate on the net, finally it should be pointed out once and for all that even those who do not have a Radeon, a GeForce 2 MX or a GeForce4, even if they cannot use Quartz Extreme, can easily install Jaguar.
More simply in the presence of a different and more dated video card, the new Mac OS X will continue to use the processor to carry out the Finder design tasks with more modest performances than those possible to a machine in which the graphics card will do the work of drawing the windows and dictating the animations of which the operating system is rich
In short, to think that only those who have a Radeon or GeForce 2 or GeForce 3 or a GeForce 4 video card will be able to use the new wrong operating system.
Equally wrong, at least according to what Apple says, to believe that only with 32 MB of Ram will you have access to Quartz Extreme. The 32M of video memory are useful for optimizing performance, but the only required condition are video cards of the GeForce2MX, GeForce3, GeForce4 Ti, GeForce4 or GeForce4MX series, as far as Nvidia ATI is concerned: or any Radeon AGP.
