Talk, Rumors, X Versus Y This article started life when I was asked to write a comparison of x86 and PowerPC CPUs for work. We produce PowerPC based systems and are often asked why we use PowerPC CPUs instead of x86 so a comparison is rather useful. While I have had an interest in CPUs for quite some time but I have never explored this issue in any detail so writing the document proved an interesting exercise. I thought my conclusions would be of interest to OSNews readers so I've done more research and written this new, rather more detailed article. This article is concerned with the technical differences between the families not the market differences.

On a side note, Panther adds another level of Parallelism

Unless you have completely closed your eyes, OSX 10.2 added the GPU as another processor to offload some of its OS duties for GUO in the form of Quartz Extreme. As it was OpenGL was already hardware accelerated, but Quartz Extreme allows all the compositing to take place in the GPU freeing up the CPU. In addition, since the Altivec unit is truly orthogonal, Shadows and Pattern fills along with 6 other desktop drawing functions are being handled by the vector unit while the rest of the processor core was free to do what it needed.

Now, with the release of Panther, Apple has added Windowing and scrolling to Quartz Extreme as well. It's never been faster or smoother and the CPU is even more free to handle the actual Apps. Panther will greatly benefit all Mac's with G4's and up. G3 Macs will also benefit from highly optimized Scalar libraries that now outperform the very well and time tested OS 9 libraries (Jaguar had previously achieved parity.) It should be a fun winter for hobbyists.
