DaveG5: What are you talking about, physics and engineering do not rule out a screenless G5 Or a G4 Imac lookalike (but with a G5.
Actually, depending on just what you're talking about, physics
does rule out quite a few things that people have been yammering for on the board. I've already done bandwidth breakdowns for screens of certain sizes and refresh rates, shown how current wireless displays are hideously expensive even when made from commodity parts that the manufacturers produce for themselves and aren't selling to another party, and also demonstrated the wattage problems with just shoehorning a 970 processor into the current form factor.
DaveG5: DUH. I highly doubt it is the low power one for the upcoming G5 that will be used in the Powerbooks, to which I was refering, there are always many chips with in a class. This may be the 970, as Apple has been reported to have chip supply problems with the dual 1.8 G5 970. We dont know though, granted.
What "low power one for the upcoming G5 that will be used in the Powerbooks" are you talking about? I've not seen any announcement that IBM is preparing some special low-wattage 970. Also, you might want to work on structuring your sentences a little more clearly, since saying that "This may be the 970, as Apple has been reported to have chip supply problems" implies that the G5 is more likely to be used
because Apple already has supply problems.
Thats debateable ofcourse so I want go there, as to list all the G5 advantages over the G4, you are convinced there is only two.
I'm convinced because I've researched the topic and the evidence shows, pretty clearly, that the only place the G5 is clearly superior is in bandwidth. Without a huge pipeline feeding it, the processors would choke and do no better than the G4.
Buss speed has been shown to have extremely little efx in most applications, of course there are some that its needed. cutting the buss to 1/3 from 1/2 would probably not make that big of difference considering its coming from just 167MHZ, this would also cut heat and power requirements, not sure how much.
Wrong. Bus speed is all that makes a difference, other than the additional clockrate, which wouldn't matter without the bus to keep it fed. It's sheer naivete to say that the bus doesn't effect the performance all that greatly, especially since it's one of the only major improvements in the newer chip.
To my understanding the G4 powerbooks have processor cycling (not sure on G5's) which automatically cut the gigahertz the machine runs at when idol or doing something light, that keeps heat and power drain down, so those chips do exist, hopefully that process will make it's way to the G5 if it hasnt already.
I already said that, you know. The MPC7447A (which is in the most recent PowerBooks) has processor staging, as do the 970fx chips that are in xServe and PowerMac G5s of the most current revision. Even so, the 2.0ghz processor still outputs over 25W at its lowest non-sleep setting, with the 1.6ghz
possibly clocking closer to the svelte 1.5ghz 7447A's 11-12W for the processor. This says nothing of the bus or any other factor.
there is a Giant market for copper heat sinks and fans and water cooling that goes way beyond the stock components you find and stock computers, they do exist, but are way too pricey, I dont think I have seen any direct replacements for the G5, just the G4 Mdd ( many users swear by them in their formally loud and hot over-clocked G4's, by quite are few venders, it's just a matter of time, you know. and a good thermal paste never hurt anyone.
I'm... confused.
Where in my post did I say that there wasn't a market for cooling solutions? The point is that Apple would have used them and brought the machine to market, if it was at all possible for them to do so. They're not stupid and they plan ahead, since the LCM is pretty obviously a futureproofing against the day that PowerPCs creep towards the place that modern-day x86 chips are already shoving the thermal barrier. There's a
very good reason that Intel is moving to the Jonas core on the desktop, after all.
I fully expect Imac AIO G5's somewhere between 1.6-2.0GHZ max. $999-$1999-17-20" within a few hours time, I hope the video is BTO upgradable to 128MB, which is most important to me, and possible pc card/pci slot (not a must but would be great to add firewire 800 card laterUsb3 or 3rd party expansion), along with a 16ms screen-170 degree+ screen)
I of course would love 1.8-2.0-2.5.
The keynote isn't until the 31st, which is around 24 hours off, so that's strike one. The price is almost certianly not coming down, what with the entire system having to be redesigned and using newer, more expensive components. Strike two. Also, the target market for the iMac doesn't really tend to use expansion cards or change anything, and that's something I bet Apple realizes. It's a simple machine for people who just want their computer to work. Strike three.
You
might see screens like the pro ones on the iMacs, but that's the one thing I think you could be right about. It's possible that I'm wrong and Apple's wrought a miracle, but I doubt it.
No more Imac G4 on Apple's site, just the powermac G4 single.
If you're talking about the store, then that's been true for months. Where have you been?
If you're talking about the main website, then I have just one thing to say:
Wrong!
