    In a situation like this, I recommend calling Vinny's Foot -In-Mouth removal service. They do great work on the cheap.

    I just want to know how he got to over 1500 posts without someone in this community realizing he was "special".

    like he says, Technology is dominated by two types of people: those who understand what they do not manage, and those who manage what they do not understand. Putts Law ... just kidding.. oh wait.

    And Steve is a Movie guy and hmmm...I smell a rumor...




    That is also the day of the grand opening of the Apple Store in San Francisco. Not going to happen...

    just for the record, he lists his native language as English. (seriously?! )

    and I was accused of being the frozen caveman... yes, running a 130nm at 2Ghz would be WAY too hot! j/k

I would be willing to bet that the 90nm could hit speeds higher than 2.5ghz with only a single processor. It's gonna be sweet when the Rev. 2s come out.



    this is the coolest post ever thank you DMBand0026.



    and btw: i think you're right - the 90nm 970fx can reach higher speeds than 2.5Ghz with only a single processor. put two of them into a dual powermac and we've got more than a dual 5Ghz-machine... wow!!!





    eh?

    Wow, I'm still amazed at the fact that the SSOI process, and die shrink resulted in about half the power output. Going from 51 to 25 watts is great. I really can't wait to see that 1.4 Ghz G5 in a Powerbook.

    Reduce your penis size using SSOI. Is your penis too large? Does it dissipate so much heat that you had to buy a 9-fan thermoweave underwear? Do girl cyborgs/androids laugh at the performance of your penis? Reduce your penis size NOW!!!

    <We now return to our regularly scheduled thread>



    Can anyone do me a favour and illuminate the whole bus-speed/multiplier situation for the G5? From what I can draw, a 2.5Ghz processor would need a 1.25Ghz bus, ie- processor = 2x bus.

    I remember all the talk during the PM-G4 days about how multipliers of certain sizes were stupid because they would leave a processor at say 1.XX Ghz. That's what we have now, G4s rated at hundreths of a Ghz. Such fun. And inane discussions like "My 1.42 is much better than your 1.25" have been a blast around the office. Amazing how we act over a few processor cycles.



    Is the bus speed all about yield like the CPU, or are we dealing with set multiplier with the G5? (currently 100Mhz at a time...)



    And BTW, I DO have Vinny's on speed dial...

    They said PPC970 supports only one 2x bus speed multiplier, i.e. FSB frequency is half the CPU frequency. Please, feel free to correct me if I talk out of my ass.



    Now, with PPC970fx, if I'm not mistaken, they speak about some elastic bus. I haven't seen any official info on this one, but its name suggests either more frequency ratio multipliers or some dynamic nature. I've also read somewhere on ArsForums that some people believe that 1.1GHz is the maximum speed of Apple's system controller, which, if true, complicates things a bit.



    In short, as far as I know, we don't know anything for sure yet.

    The PPC970 supported 2x, 3x, 4x and 6x multipliers. Its bus has always been known as an elastic bus and Apple's system controller should scale just as easily as the bus. It's just a matter of how much heat it puts out and if the signal integrity can be maintained, although I doubt there will be issues on either count.

    apple will probably use that new SSOI 90nm fabrication-process too for the system-controller? any hints on that?

    You should take a look at Hannibal's excellent article at Arstechnica:

    Note that the 970 has a (comparatively) large instruction cache.
