    This is the first mention of a release date I've seen for a product utilizing the 1.1ghz PowerPC 750GX;

    "XCalibur 1100 750GX CPU Stock - 4 weeks"

    This lines up with IBM's roadmap slating a production date by December. Sooner than later looks like it.

    Hopefully we'll be seeing 1.1ghz 750GX upgrades announced around this same timeframe. 750GX is a drop in replacement for the previous 750FX, so it should be a piece-of-cake to utilize the faster more advanced 750GX into already existing 750FX upgrades. Heres three likely candidates;

    A 1.1ghz G3 with 1mb of 1:1 cache in a Pismo would really be impressive, and likely give the new G4 Ibooks a run for their money in terms of performance.... considering the 750GX's effiecient 5-stage pipeline design, 1Mb 1:1 L2 Cache (4 times that of the Ibooks G4) and the extra 100mhz in CPU speed.

    Shouldn't this thread be in "Hardware Discussion and Help"?

    Still a G3.. no AltiVec...
    The GX (Mojave, or Gobi?) isn't the one rumored to have an SIMD unit. If Apple were to use one of the newer 750XX G3's they'll have an Velocity Engine on it.
    Maybe Apple will use them in the near future, but branding them as a G4. And rightfully so.

    This GX news is very good for Apple. Because the assumption should be that anything the GX can do, the VX will do better.

    The PPC 750 VX is IBM's announced G3 + AltiVec processor. So if the GX has 1 MB of L2 cache, the VX probably will. I have no doubt that the IBM release of the VX at speeds of 1.25 GHz and higher will be the end of Apple using Motorola G4 chips.

    Lets hope so, moto stagnation has gone on for far far to long.

    Even though IBM is the "good guy" and Moto is the "bad guy", or should I say scapegoat, IBM's 4-stage G3's will never clock as high as Moto's 7-stage G4's if they are produced on similar processes. Heck, Moto made it to 1.42ghz on 180nm and IBM is just now creeping up to 1.1ghz on 130nm. The 7447 is probably very safe from IBM, for the time being.

    Has there ever been any confirmation that this supposed "G3 w/altivec" really exists. has there ever been any sort of verified IBM information about this. I don't recall anything more than a few obscure rumors a long time ago.
