There is another possibility which may explain the move to longer ship times, yet there are still promotions going on right now.

Maybe Apple being the super secretive company it is, is now changing ship dates earlier even when it has inventory. Hell, they still can do same day shipping regardless of what the web site says.

Doing something like this would throw off the rumor sites considerably.

...HyperTransport bus on the next chipset for AMD will be 1.6ghz on unidirectional dual-channel, just like the G5's current architecture. The VIA K8T800 chipset, which is in fabrication now with multiple suppliers on the PC side, is reaching 1.6ghz easily and in volume...

I may misunderstand what you are trying to say here and perhaps I misspoke when connecting AMD with FSB speeds over 1GHz (perhaps I was reading about an overclocked Intel chip), but I don't think that HyperTransport speeds are really comparable to the FSB on the PPC970. The FSB on the PPC970 also carries the memory interface while AMD's Athlon 64 has a built-in memory controller. Obviously there is a limit on how fast you can run the connection between the PPC970 and the system controller. I don't know how far Apple can stretch that speed beyond the current 1GHz. It should be a function of the 970fx, the motherboard, and Apple's custom-built system controller. I suspect that only Apple and IBM know the actual limit. Similarly, I don't know whether the original PPC970 or the new 970fx supports bus multipliers other than 2X (it would be nice if it did). Thus, when you combine these two unknowns it seems that there might be some uncertainty about what processor speeds Apple's current G5 design can actually support.

The simple (or obvious) solution would be that they can support a FSB speed of at least 1.3GHz. Combine that with the existing bus multiplier of 2X and you can produce:

2.6GHz processor (2 x 1.3GHz FSB)
2.4GHz processor (2 x 1.2GHz FSB)
2.2GHz processor (2 x 1.1GHz FSB)

Frankly, if Apple can do that then I'd say that they are closer this year to having the world's fastest PC than they were at last year's WWDC.

Does someone want to check my math? :)

I think that it would be a mistake not to create a lower-end tower with a single processor and the current features of the G5s. That would allow an easy differentiation between the pro and consumer lines even if there's no change in processor type (970 to P5D - Power5 Derivative). Also, for those who cry and moan over there not being a cheaper G5 with expandability and options, the iMac is the worst of both worlds, since it would hideously limit what Apple could do with the machine while also denying upgradability. A tower is the only compromise that makes any sense, and it's the only path that would allow the supposed Holy Grail that I keep hearing people whine over - a headless "iMac."

pleaase forgive me for being sotallyuntober....but Ill make my argument anyway :). Although I agree there should be a differentiation between the pro and consumer G5 lines, I do not think there should be G5 tower's that consist of single processors. Although the iMac may offer very little in terms of expandability, people purchasing current 1.6 singles are not looking to deck it out and add every feature they can to it. It is the cheapest G5 out there, and although fast, it is only sold because it is a G5 processor, not because it is a power hungry machine that will devour art/video work. I would suggest apple offer the current 970 machines as consumer models. with 1.8/2.0 duals beign offered. (1 model up or down too, but that is dependant on what professional models they release.

An iMac (headless) offers a cheap G5, much cheaper than any curent tower. i dont even care what it looks like, the fact is selling a base of a iMac could be cut down to 800+$, which would bring alot more costomers into Apples ballpark. Considering if they dont have the money to spend on a beautiful LCD display, they can use their current CRT monitors and be haoppy. IT would distinctly separate the low end computers, mid-level consumers, and professional buyers with all 3 levels. Offering all types of pricing options, along with bringing their monitor proces down due to the separate iMac sales instead of the packaged current deals.

Sure can: Tower.

Your such a smart ass :p I wish I coould prove you wrong, but I know your probably right. But what would the fun be in that if you had no one to argue with! :D Im just offering my personal opinion based on the entire consumer market, and not just the current rich, professional based buyers. I want apple to steal every comp usa, circut city, and best buy customer there is, and be able to offer something that can make anybody at least think about buying it. Oppossed to the cuurent huge price gap between a decently loaded AMD computer and Apples low end computer.


The 7455 can run at 35w typical, but the reference you give does not state either the conditions, the clock rate, or anything else that causes it to reach that point. As such, it's more than a little irresponsible to be bandying about that number as if it proves anything, since we've got hard numbers on clock rate and heat in the 970 and 970FX. The P5D, should it make an appearance in the upcoming product cycle, will almost certainly be a pro tower process and not at all make a blip in the consumer market.

I know, I know. :( But whatever specs or heat numbers we throw out there, Apple simply MUST release a G5 iMac, because it is what the public desires. You cant offer a stunning processor 1 year ago and keep all your your models on its predecessor and expect sales to climb. Consumers arent stupid, well, they might be but they still know the difference between getting a G5 that they saw in the commercials, or a G4, which by even elementary mathematics they can tell is outdated. ( "G5 - G4 = G1 | so the cool model is 1 better than the one I am spending 1800$ for...hrmmmm....") Makes no sense, but Im drunk and felt like doing math. But for the most part, the public doesnt want to spend 2000$ on something it knows isnt even the best they offer, and that seems like a waste, especially in todays market when a spanking new PC is outdated in 6 months.

So, as we can see, even the single 970FX loses to two 7455 processors (which are hotter than the current MPC7447A), especially at maximum wattage consumption and maximum heat output. Load those babies down and watch the temperature rise... Hell, look at the single 1.8 G5, which throws out an ungodly 1466BTU/h, or some 3-4 times the heat output of two 1.33ghz previous-generation G4s. I threw in the dual-processor G5 just to show you what a system with fans that could drown out aircraft engines do with the heat - lose to the G4 all over the place in heat and power draw.

Oh, and those are Apple's numbers, so if anyone has a reason to spin the G5 as being cooler, it's them. No dice.

Dead God, I hope that you're wrong about the iMac. I like having a computer that doesn't have any fan noise, and they're going to need some high-speed blowers to get rid of the excess. If the formfactor is completely redesigned, then it might be possible we'll see a "G5 iMac" that can double as a hairdryer. ;)

In all seriousness, the best path to take here is to build a real consumer tower with the 970 or 970FX, not some absurd bastard child of the iMac that could be used to toast your breakfast in the morning. Well, maybe there is a market for the iToaster... :rolleyes:

No matter how right you may be, consumers dont care about the technology involved in the product of keeping it quiet & cool, they just want the "G5" name, plain and simple. You and I desire the same thing, but I am just putting out the perspective from everyone I have talked to about them, and while 70% of those people just want a cheap G5, 30% want a small for factor. And to add to this, which you already make you point abundantly clear in your previous posts that Apple is VERY far away from a powerbook G5, and although I agree with you, people dont care. You and I understand the specific details of engineering it and how difficult it is. Mom and pop just want it because it looks cool, and it beats the hell out of the comparable pentium M, and if Apple never pulls through on this front, then they will eventually loose.

If they cant fit a low powered G5 into an iMac @ WWDC, then powerbook G5's are a LOOOONNNGGG ways off. And I dont think they can afford that. And although what you propose makes total sense to a business o supplier, it will not keep apples 5% marketshare growing, since people eagerly want iMac / powerbook G5's. It doesnt matter how they do it, its just the fact that they do accomplish it.

And please dont come down on me too hard, I know 1/2 5his stuff Ill regret in the morning, but its the best drunken argument I could make! :p

Pretty gutsy for your first post. People are just having a good time discussing the things they like. For what it's worth, he was far more on-topic than me. I just thought it was funny.

As for being on-topic, after the huge mess that math spawned, I don't know. I want new G5s. I honestly won't be surprised if they are not 3 ghz. I can hope, and I'll be let down a bit if they're not, but I will still be buying one. My G4/733 is too aged to live another year, and people are chomping on the bit to get it handed down as a used one.

I will be buying the top of the line, regardless of what comes out. I'll feel gipped if it's 2.2, though...

At least without a new graphics card. :p

Frankly, if Apple can do that then I'd say that they are closer this year to having the world's fastest PC than they were at last year's WWDC.

For comparison, this year the competition for the title is:

  • Opteron 250 (dual 2.4 GHz, 1 MiB L2 cache, 2*2.4GHz FSB)
  • Xeon 3.2GHz (dual, 2 MiB cache, 533 MHz FSB)
  • Itanium 1.5 GHz (dual, 6 MiB cache, 533 MHz FSB, 24 GiB RAM)

Let's hope that Jobs uses these systems for the comparison, and not use some kind of "justification" so that he can use a single processor 3.06 GHz system for the PC.


Also, when you're comparing FSB speeds, think about a couple of things:

  • Apple is using 400 MHz equivalent memory
  • The G5's bus is 2*32-bit unidirectional
  • Intel's bus is 64-bit bidirectional, AMD 128-bit

So, the bus is more than just a single frequency number....

This also means that if the next G5 uses a 3:1 multiplier (say for a 2.4GHz with 800MHz bus) it will still be at least as fast as the memory!
 
Irish Car Bomb = drink?!

Thanks for the explanation, iReilly.

I'd never heard of the irish carbomb drink until i had one at a UCLA bar in Los Angeles! And I live in Britain!

It's not a very nice drink and is very expensive. Not that great a name either.

Anyway, G5s need to be updated: here comes WDC!

I majored in Electronics Engineering, and yah, that's pretty much it. ;) We essentially obtain minors in Math and Physics while we pursue our degree, (at least at the univeristy I attended), so I've been through all ends of things. The thing I find most interesting is the application of all that raw knowledge. Sure, you can learn how to do Fourier transforms, 3-dimensional calculus, electromagnetic induction, and all those wonderful things, but in Engineering we learned how to apply them in the real world, which was cool. You can teach Communcations Theory to whoever you like, and you can learn all about the theory of discrete sampling and the Nyquist sampling rate, but unless you can go into the lab and build a radio from scratch (as a simple example), constructing the circuits and all that, what's the point? ;) :cool:

I can honestly say I never heard that one, not even in my first-year classes. Of course, with having to memorize constants like Planck's constant, the permeability of free space, Rydeberg's constant, etc. ad infinitum, coupled with formulae regarding waveguides, DSP, Shannon capacitance, Hamming codes, electgromagnetic waves, and <shudder> Maxwell's equations, remembering V=IR was the least of my worries! ;) :cool:

Hmm, "Clearing Out G5s"... I guess I better quit for now and get back on topic... :eek:

Hehe, allright, just to clarify what I believe mercury already said, I was not appreciating terrorism. Irish car bombs are one of the best , albeit pricy, drinks Ive ever had. To be honest, Id never even thought about the name in that sense because when you watch them when they are made, you understand.

Sorry if I offended anyone, but like I said, i was sotallyuntober. :cool: I was just trying to have fun and although the argument wasnt that great...at least I could still make sentences! lol
 
why people want PC users to SWITCH is beyond me.
Honestly, it is better if Apple just has a few million users, because then they can spend the money on r&d for better stuff, not on like tech support and help for people who can use and know the Start menu like the back of their hands but cannot understand what the hell Finder is for. Gah.

Let's hope that Jobs uses these systems for the comparison, and not use some kind of "justification" so that he can use a single processor 3.06 GHz system for the PC.

I don't think those systems qualify to be named a "PC" (personal computer). The Itanium is definitely a workstation/server, the dual Xeon is arguably the same, and I don't think a dual Opteron would qualify either. True, some would argue that the G5 should be considered or classified as a workstation, but then there is the question of price (those Intel systems are likely to be much more expensive than any Power Mac G5).

I think it would be fine if they benchmarked against single-processor PCs. Either an Intel Pentium 4 Extreme at 3.4GHz or the fastest AMD Athlon 64 that they can locate. And then they could add a repeat performance on the dual Xeon. Of course, if Apple's marketing is working overtime they should probably choose the latest Intel Pentium 4E (Prescott). That would give Steve Jobs the ability to take some "cheap shots" about the Prescott's relatively poor performance against last year's P4 designs. And I suspect that against the Prescott the heat generation of the G5 suddenly starts to look not too bad. And I'm sure Steve is going to talk about how Intel is dropping MHz/GHz as a way to market their processors (i.e. the MHz myth is finally confirmed).

Yes, that's a valid point.

In any case, I still say that comparing the design limits of the Athlon 64's HyperTransport-based FSB against the G5's FSB is problematic. The Athlon 64 processor design is arguably superior with its built-in memory controller and HyperTransport link and IMO that forces one to classify the FSB design on Apple's G5 a completely different "beast." I'm not suggesting that the G5 FSB design is better. In fact, the opposite is probably true and for that reason I won't just assume that the FSB on the G5 can run significantly faster than the current 1GHz.

... so will i ... i just bought a vintage dual g4 1250 mhz today ... just to have some work done until the new g5 will be announced and then delivered ... my old dual g4 450 mhz was just too outdated for some serious gfx- & vfx-stuff ... and for a price of approx $1'200.- (with super-drive) i thought it is cool ...
but then again i really want a new g5 and please let it be really fast !!! but i buy the high-end anyway, whatever chip they'll use ...
the future will tell ... let it be fast ... let it be fast ... let it be fast ...

Probably has something to do with the market.

To have a few more Mac users always helps market wise. Keeps the developers happy as well as long as the market is big enough for them to make a profit. I for one, would hate to see MSFT, Adobe, etc. pull out because the market share is too small to make it profitable for them to continue support.

For those of us who have owned and used Macs since the early 80's, we have seen so many changes. Maybe in the back of our minds, we feel that the bigger the market, the better chance of not loosing any more key developers.

Edit: And of course Apple itself. Then we would be stuck in a Winders world! :eek:

Please note: You may not add iPods to orders for the Power Mac G5 1.6GHz. [May 21 2004]
 
thatwendigo provided some useful links to data on the Power Mac G5 and Xserve G4/G5 power consumptions and thermal outputs (thanks). I looked for additional systems and I think I found some interesting comparisons.

According to Apple's data the 800MHz G4 flat-panel iMac consumes 130 watts max and produces a maximum thermal output of 445 BTU/hr. This was the Jan. 2002 model with the 15" LCD.

Now let's compare that to the single 970fx-based Xserve G5 running at 2.0 GHz. According to Apple's data this configuration requires 170 watts max and produces a maximum thermal output of 580 BTU/hr. This is for what they call a minimum configuration -- Single 2.0 GHz G5 Processor, single 80 GB Apple Drive Module, 512 MB ECC RAM (2x256 MB DIMMs), no PCI cards, no video. Adding a PCI video card apparently increases the power consumption by 10 watts (according to Apple).

Obviously, these are quite different systems and the iMac includes a flat-panel display. But, based upon this data it seems possible that you could handle the power consumption and thermal properties of a 970fx in an iMac-like design. It might even be considered easy if you dropped the 970fx speed down to 1.6 GHz.

Opteron/Athlon have an on-chip FSB/memory controller that runs at clock speed.

HT is an I/O bus and a cache-coherency bus for MP - it is not the memory (FSB) bus.


And really, what does "superior" mean? The Xeons with the 533 MHz bus lose all of the "spec" battles, but they win a good number of the benchmarks. Actual delivered performance vs. a few isolated technical specs.

Which is more important - hot numbers on the tech spec sheets, or hot numbers on important application benchmarks? I'll go with the benchmarks....
