    Because of "geekmeat"'s post, I would like to take this oppertunity to again ask that when the switch to vB is made, 2 new forums be created.

    Senior Apple Tech Discussion

    Senior General Tech Discussion

    To post in these forums you will need a post count of over ~250-300, and have been a member for ~3-4 months.



    Umm, methinks I don't like that idea. Some of us may prefer to lurk for weeks at a time and then add our $0.02 in when we feel we can contribute. Although I definately see what you mean B.

    girls, before you get more off topic, please post that suggestion in the suggestions forum. thank you.

    /back to your regular thread schedule

    I did, but no-one ever visits that forum

    Yeah, 100-posts would probably be ok.

    Lurkers become junior posters then become senior posters.

    as for motorola not having released their embedded processors based on the G5(e500 compatible core) well your wrong.

    they are released!


    Any links??

    This suggestion's been suggested before, and there's been very little interest in it.

    If you posted it in Suggestions, and nobody replied, that's probably a fair gauge of the lack of interest, no? Other threads get replied to in there.

    At any rate, this ends this discussion in FH.

    you guys take yourselves waaaay to seriously.

    im a apple fan....o.k fanatic,but i have a little fun with it.

    i read this board all the time and there are a few people such as the "programmer" whose post are technical and detailed and on point.

    BARTO, you sir are a wannabe so step off me ok?

    ive tried to show respect to other posters but once im single out the gloves come off.

    i still say apple has something special planned in 2003,and its not the 970!</strong><hr></blockquote>

    OMG!!!! new mot G5! W00t!!!! do u now if this g5 will have full ddr and rapid IO and hypertransport? any info on speed? will it go really fast like 5ghz like the pentium4? what about nforce, can the g5 use a nforce mobo? what about amd, i heard their doing somthing with apple and nvidia? oh and is the g5 compatible with the raycer chip?

    Well, it's maximally legit I would guess, coming from Motorola and all that - OK, OK, their roadmap has always been from them, too, which however never really made it any more true... . Anyways, this is the first document to actually state *real* dates, such as 2nd quarter/2003 for availability of the 7457. In addition to the faster bus and larger L2 cache, the larger L3 cache will also help the G4 to stay fed with data. Concerning what Kurt said about a special deal that Apple seems to have with Motorola, even the 1.25 GHz G4 part isn't listed in their technical documentation yet. The 7457 looks like a great proc for new Powerbooks -&gt; new PB in SF?

    Here's what I know about the G4--all based on documents/PDFs from Moto. Unfortunately, I don't have links, since I downloaded the PDFs and then forgot where they came from. Anyways, here's what I could glean from them:

    Short term:

    Sometime in 2003 (probably announced in Jan or Feb)

    ?1.3 GHz claimed, but the 74555 is still listed at 1 GHz, and the 1.25 GHz part is in production. Based on this, we can assume that the G4s sold to Apple will be around 1.5 GHz.

    ?200 MHz MPX bus.

    ?The same power consumption as the 7455 is targeted, which leads me to believe that this G4 will be fabbed on a 130 nm process.

    A decent step in the right direction...I particularly like the faster bus, although I still don't think it's enough.

    Long Term (as in next 5 years):

    ?3+ GHZ

    ?Rapid IO bus (to be implemented on all of Moto's CPUs".

    3 GHz in 5 years is totally pathetic, so we can only hope that it's a conservative estimate, or even better, that within a year Apple is no longer dependent upon Moto. I fear that Apple will still need Moto to supply G4s for the consumer Macs like the iMac and iBook.

    This information is not rumor or speculation, it's all based on info from Moto's own PDFs. Based on the short term info, it's not entirely impossible that we actually will see a 1.8 GHz G4 at MWSF. If Moto migrates the G4 to 130 nm then this seems like a reasonable although optimistic target. Furthermore, the new Powermac case seems designed for CPUs that are both hotter and more power-hungry than the current 7455 G4s they house.

    My own overly optimistic scenario is that Apple announces 1.8 GHz G4 Powermacs in January, with the high end shipping in March. Then at MWNY or soon after, Apple will introduce PPC 970 based Powermacs at about the same clockspeeds as the G4 Powermacs. Of course, the 970 Powermacs will be twice as fast as the G4 Macs, and Apple will use the G5 angle for marketing.

    More realistically, Apple will introduce 1.5 GHz Powermacs in Feb '03 and let them stagnate for nearly a year. At MWSF '04, Apple will announce the PPC 970 Powermacs, clocked to 1.6 GHz with 266 MHz DDR RAM. At MWNY '04, Apple will finally get the Powermacs up to 1.8 GHz, and give them faster 333 MHz DDR RAM. Meanwhile, Wintel PCs will decimate even the 970 Powermacs because of the substandard RAM used by Apple.

    So I was thinking (rare occurence) if the current 1.2 ghz G4's are really overclocked 1 ghz and since the the current g4 cases have major fans in them...perhaps Apple will be able to overclock whatever new G4's moto hands to

    1(real rating) * 1.2 (percent overclocked) = 1.2

    1.5 * 1.2 = 1.8

    1.8 * 1.2 = 2.16

    Apple could release them at the original speed and save the overclocking for later...but hopefull not...

    They aren't. They are speced by Motorola to run at 1.25GHz therefore they aren't overclocked. Besides which Motorola announced the 167MHz bus was coming long before these arrived so clearly they had it planned.

    Telomar are you sure? I believe even the Register has referred to the current top of the line powermacs as using overclocked g4's... oh well if so there goes my theory...

    No offense, but the Register has 0% Mac-cred.

    These are tested in either the snort-towers or a simulated snort-tower environment, to see what GHz they run at. They are not overclocked, although without the mofo fan they would probably fail.

    They definitely aren't overclocked. If I had to take a hunch I'd say they are/were a developmental step somewhere between the 7457 and 7455.

    I doubt they ever really planned it for widespread release probably due to power or heat, which the embedded market isn't terribly fond of. Apple likely wanted something better than what they had and couldn't wait until the 7457 so this is what they got slotted in.

    I struggle to really think of anywhere that has much credibility when it comes to macs. Apple really does do a very good job of keeping its information secret and that is astoundingly difficult to do.

    They either have a staff that really loves the stuff they are working on and don't want to spoil it or put Apple out or a staff that is simply petrified of the possible repercussions.

    The third option is that fewer people care so nobody hunts it down or releases it quite as much.

    Two-tiered mac rumor discussions? Some people need their heads checked. Seriously. WTF?
