IBM's June 2003 Processor News article discusses the PowerPC 750GX in detail.

The PowerPC 750GX processor is sampling in July 2003 with production targetted in December 2003.

Manufactured in IBM’s advanced 0.13-micron copper process with Silicon-on-Insulator technology, the 750GX will be offered at frequencies up to 1.1 GHz. The 750GX expands the capabilities of the IBM PowerPC 7xx processor family to support more performance-demanding and power-sensitive applications. The new processor is ideally suited for a variety of systems, including networking, communications, storage, imaging, computing and consumer applications.

The 750GX will be offered at up to 1.1GHz and has 1MB of L2 Cache (Twice the 750FX) as well as various architectural improvements -- and is pin compatible with the 750FX.

The iBook currently uses the 750FX Processor which maxes out at 900MHz.

So if I read this right, the chip could be used as a chip-to-chip replacement for the 750X? In other words, a quick and painless upgrade for your existing iBook, or buy a new one and reap the benefits either way.

If I understand, then cool. If I don't (which wouldn't suprise me...) then too bad. I'm always game at keeping the legacy machines alive for that much longer.

Sweet. Zippier iBooks just in time for MWSF04.

Upgradeability of older iBooks would be highly unlikely.

as long as there's one iBook that's got one of these and it under $1K :-D that would be cool

Looks like the G3 for the iBook is alive and well!

3 Chip lines in Apple Hardware now?

Obviously this announcement doesnt confim that apple will use it, but damn..

G5 on the high end workstation/servers

G4 on the pro laptops and consumer desktops

G3 on the ultra-light ultra portable iBook


Pretty cool that they have several options now🙂

up to 200-MHz operation of the 60x system bus interface with additional bus pipelining.

Does this = 200MHz FSB?

I think a 200 MHz increase in speed in the iBook, still with no AltiVec, is not much of an upgrade to the iBook. I mean sure...if Apple MUST keep a G3 in there, it's nice to know faster speeds are coming. But this is certainly no reason to rush out and buy a new iBook, or something to be thrilled about.

Cool! Faster iBooks! I hope these will have Altivec. 1.1 GHz sounds pretty good, but Apple has been updating iBooks 100 MHz at a time. I wonder if they would switch to a 1 GHz low-end and a 1.1 GHz high-end.

i don't see any altivec stuff in their block diagram. wasn't gobi supposed to be the g3 + altivec? (or was it sahara or whatever it was?)
i sure won't complain about faster chips in anything. bring em on!

No, Mojave (750VX) was supposed to introduce AltiVec compatible functionality.

As good of a place as any to ask...

I keep seeing the term "embedded". What does this mean in reference to CPU chips?

Thanks for letting me ask. I'll go away now.🙁

Too many names.....let me see if I have this straight.

Sahara: Current iBook processor
Gobi: Faster processor
Mojave: Altivec enabled processor

Is that right? And if it is, when is Mojave coming?

When the CPU is used for applications other than a PC such as a router or hub they call it an embedded chip.

I would like to buy an iBook just not before it has a G4 or equivalent proc.

well if the high end ibook goes to 1.1ghz then the low end powerbook g4 will be at like 1.25.. sweet!

I see this as tremendously helpful for upgrade makers that are starting to push 750FXs into SL iMacs and old G3 towers. I certainly know that this is incentive enough to upgrade my again iMac DV (which can, btw, now be upgraded).
