Asher can correct me if I'm wrong, but the PPC G5 is just a crippled version of one of IBM's POWER chips for servers IIRC.
It was never designed to go into a notebook, and will probably be too hot to ever go into one. But Apple sells a lot of Powerbooks (people love the things: they are attractive and reliable computers) and really needs a better chip than the aging G4 in them (well - people other than me – I don't need the power).
Hence they are going to have to get a new chip from somewhere. I heard rumours about a version of the G5 for notebooks, and there's all this dual core nonsense, but that's all rumour and will probably come to nothing. |
The G5 is a castrated verion of IBM's POWER4 chip for servers, with a VMX unit (VMX is IBM's name for Altivec, since Altivec is trademarked by Motorola).
The G5 is actually the PowerPC 970 (130nm process), and the most recent version is the PowerPC 970FX (90nm process).
There are dual-core versions of the PowerPC 970FX, but they're still in the engineering sample phase.
There is rumoured to be a low-power version of the PowerPC 970FX for "blade" systems, but I can't say anything more than that.
POWER5 is a much more advanced chip than POWER4, and the vast majority of IBM's engineering work is focusing on that POWER5 and POWER6 families.
For example, Microsoft is paying a pretty dollar for a "crippled" version of the POWER5, but with a vector unit and tri-core.

I knew that much. I couldn't remember which POWER chip it was.

In other words, there is.

For the XBox, right?
