Cell processor may not be an easy sell to Apple

We all know that the latest and great processor in the Mac world is the
G5. Made by IBM and used by Apple in its high end
PowerMacs these processors pack some serious punch. Recently IBM, Sony,
and Toshiba announced that they are jointly working on something called the
Cell processor which will be making its debut in Sony' Playstation 3.

IBM went to great pains to point out that the new Cell processor (which at the moment clocks in at  speeds up to 4Ghz) is PowerPC compatible fueling suspicions that Apple may adopt this new chip for its computers.

eWeek's John Rizzo has written an
excellent article detailing why he doesn't think that Apple will be using the Cell anytime soon. He points out that while it might be trivial to get OS X to run on a Cell processor, tweaking the OS to make it run faster on the new processor will take a long time and a lot money. Also, the Cell's core is much simpler than the one found in the G5; it is only capable of issuing 2 instructions at a time while the current G5 can issue 4 times as many.

All of that information can be found on the first page alone of the three page article; this article is dense, folks.
Rizzo builds a solid case, and he has convinced me that Apple will most likely not be using the Cell processor any time soon.
