Since nobody has mentioned yet, I will:



<a href="http://www.thinksecret.com/news/g3gobi.html"; target="_blank">http://www.thinksecret.com/news/g3gobi.html</a>;



ThinkSecret is usually quite accurate, so I'd guess we're going to be seeing some faster iBooks soon. I wonder if this version includes the SIMD implementation that has been on IBM's roadmap for some time, or if its just a clock bumped G3 (with up to a 200 MHz bus)?

    So, ThinkSecret is saying the mHz of the G3 will eventually outpace the G4?

    This is interesting. Why would Apple take shipments of it when the iBook has just been bumped? I have never heard of the term GOBI before could this be the elusive G3 plus Altivec?



    Quote:While the chip line has been publicly announced as high as speeds of 1 GHz, the GOBI chips will clearly exceed that.



    Why will it clearly exeed that? Maybe IBM lengthened the pipeline? The 750FX in the present iBook is already made on the SOI 130nm process. this processor might class itself out of the G3 moniker and may very well be IBM's long awaited G4. Hope springs eternal.

    The article is short on details, but it sounds to me more like the G3 will keep pace with the G4, MHz-wise. It may be hard to remember, but the G4 hasn't been stagnant since the 7450 redesign. It might not be as much as we (or Apple) want it to be, but it's been scaling up steadily.



    Also, the G3's move to RapidIO will occur at the same time as the G4's (with the 7457-RM), if the article's right.



    As for the speed increase, it could be a redesign, and it could be the same design on the new .1 micron process at the Fishkill plant...

    Motorola does not have the feature set for the 7457-RM finalized yet. In fact they may even dump it. Same with any 750 from IBM that's on the roadmap.

    If Apple is getting parts on this new 750 now then all that's missing is the details.

    That's a given for any part that won't appear until 2004. But the plans for both chips dovetail nicely.



    I doubt that Mot would dump the G4, though. I can see them cutting R&D on a dedicated desktop processor, but I think the G4 has a long and profitable life ahead of it. That's the sort of thing that Mot SPS needs right now.

    Yup.

    Mmmmm....IBM G3 with DDR bus and VMX... arrrggggrrgrr

    Yeah this story just doesn't gel. They haven't made it to the supposed 1Ghz limit of Sahara yet, so why are they "taking delivery" of new G3 chips already? (Gobi, Sahara... what's next, Death Valley?)



    I suppose G3 + VMX is an explanation. This new "G4" chip could go into any or even all of the rest of the line that's using a G4 now. But somehow that just doesn't seem plausible.



    If I had to guess, I'd say this story is a false lead.

    Think secret is just the best rumour site around.You have to believe that this is true, I wonder if we are going to see the ending of Motorola chips in all Apple products at MWSF.



    If this G3 supports RapidIO, does it also have a vector unit?

    I wouldn't say you HAVE to believe them but I do give them the benefit of the doubt. Before RIO, though, I would expect an optimised 60X bus like MPX and maybe even DDR-ified. THEN it would make a good replacement for the Mot G4 even for the towers. 512K L2 cache VMX and better bus would be what it takes to replace the G4. Nothing less than that will make Apple move this to their pro systems.

    Okay, AI's search function doesn't seem to be working right now, but perhaps we have heard of 'GOBI' before... can anyone recall those riddles posted earlier this year, having to do with 'dolphins romping in the great desert', etc.? At the time everyone thought they had to do with Sahara. Perhaps they would make more sense now.

    I am very excited about this, so I just have to post again, sorry I'll see the doctor next week.



    10.2.3 is the best upgrade since 10.1 and it has improved OSX so much that if we really do get full DDR G3- VMX etc, etc this platform is going to be well on the road to getting the speed crown back again.

    Gobi is a desert, just like the Sahara.

    Hello everyone,



    Reading the comments here, I see that our article was worded poorly. I apologize for this, and hope that it's clearer now.



    There are three chips at issue here: The first -- code name is unknown -- has just been delivered to Apple. Presumably these new chips will be close to 1 GHz, the unreached target that was announced last year. The second is GOBI. The third is tentatively set for 2004 and, yes, will be the G3's move to RapidIO.



    In mid- to late-2003, Apple will have several chips at its disposal: IBM's PowerPC 970, Motorola's paltry PowerPC 7457 speed bumps, and these "GOBI" G3 chips. Should be pretty interesting, and since the GOBI chips will exceed 1 GHz, it's fair to say that the G3 will roughly keep pace with the G4, in terms of clock speed.



    Admittedly, additional information on this is slim -- just about all we know is in the article -- but if there's anything else I can clarify, just let me know.



    -Nick

    Nick i'm sorry for this off topic response...but i've been wanting Apple to buy Macromedia forever...and the Register has it that Microsoft is going to make a bid for it...this could screw up everything!...imagine IE though only browser that works with flash! argh...anyway...Nick would be great if you had any info on this for a future article....Why or why didn't Apple just to a hostile takeover when Macromedia was 6 bucks a share...I know it might have pissed of Adobe and Microsoft but....

    So,



    "No Name" - closer to or at 1GHz G3

    GOBI - greater than 1GHz, but no other features in the TS article

    successor - GOBI + RapidIO



    Is this correct?

    IBM is and always will be the sh*t. No one can touch their R&D. The current G3's are only a 5-stage pipeline compared to the G4's 7. Aren't the next gen G4's supposed to be 10? I will take a GHz G3 with 512 L2 at 5 stages over a 1.2 G4 at 10 with 256 L2.

    The 7457 will have a 512KB L2 cache AND support for L3 cache. But I don't think there will be any other major changes besides the bump to 200MHz MPX bus support. The core should stay the same just shrunk by the 130nm process. Should be interesting for comparison.

    I hadn't heard about Microsoft trying to buy Macromedia, but I have heard that Microsoft is creating their own version of Flash, called "Sparkle." If Microsoft does buy Macromedia, I'd imagine they'd kill-off Flash right around the time they release "Sparkle." At least, I think I remember that "Sparkle" is a Flash-like product; I might not be remembering correctly so "Sparkle" could be a product that is supposed to compete against something else.

    I have documents (from IBM) saying that the updated 750FX is named "Polaris" and the next generation G3-processors have the name "Mojave" (yet another desert). Mojave is probably an entirely new core, sharing development with the 4x0-series embedded processors.



    The Viper-core (2.4 DMIPS/MHz) starting at a 100 nm-process will be shared between the Mojave-processor and an Orion-processor witch will be the next generation embedded processorsafter the 440.



    Polaris is up to 1.2 GHz (2003)

    Mojave is up to 1.4 GHz (2004)



    I have no records of any Gobi-processor, but it's resonable to believe that the updated 750FX is not named Polaris but Gobi since 750-processors all share desert (Sahara and Mojave) names and 440 share stellar names (Aurora and Orion).
