How can you conclude this after I pointed out the performance edge given to the Power4 by it's large L3? Do you think that data goes nowhere on the PPC-970? If it's not in the 32 meg L3, it's in RAM, and the reason why the PPC-970 looses is because the RAM is slower than L3... hence we can conclude that memory performance matters.
I'd like to make a comment on the bus speed and memory interface of the 970....
If DDR memory is available at 900MHz (which it currently isn't) by the time we see--if--this CPU in an Apple computer, 900MHz DDR memory would nearly outpace the speed of a L3 cache, despite a greater distance for the information to travel (all the way to the system memory rather than a few millimeters to a cache).
Granted, 900MHz DDR memory will only find itself in video cards, and even then probably not for at least a year. Plus, it'd probably cost the equivalent of a kidney on the black market.
So, we'll probably see DDR400 or DDR533 by the time--if--the 970 winds up in Apple computers, which would still perform extremely quickly (roughly 1/2 the speed of an L3 cache).

I think it is obvious that "it will be slower then x86" means that it will be slower in clock speed. How long has it been that a PPC chip out clocked a x86 chip in clock speed. When has a PPC ever been slower in actual work done per cycle? Look at it this way the PPC is like a V-8 engine and the x86 is like a 4 cylinder engine. Sure they both can go 60 mph but think about how much faster the 4 has to rev to get it going that speed? No matter what kind of performance upgrades you can add to that 4 cylinder it is still not going to be as efficent as a similarly equipped V-8. Think of it as Fast and the Furious vs. 70 muscle cars if you want to

Sorry about referring to the 7470 as if it were real, the rumors were so persistent, it's so engrained in my memory from those SpyMac and MacOSRumors reports.
However, MacOSRumors was dead on with the Apollo, and the 7470 could very likely be real.

Apple built an entirely new enclosure without a new processor. They probably didn't do this if they only intended to upgrade to something better, right?
My guess is that whatever they had originally planned didn't pan out in the time frame that they hoped for.
Whether it be a new processor (G5?) or some revision on the existing formula (quad processor G4s?), Apple clearly intends to put something that uses a lot more power in these cases.
Even if they intend to keep the old G4s in these new cases for a while, it still might make economic sense to move to a single case with over-rated power supply. That can certainly be cheaper than supporting the manufacturing costs of two completely different, Apple-custom, case designs.
The other reason might be that Apple intends to offer "upgrades" to the G5 for users who have purchased one of these new G4 machines. It would simplify the upgrade program costs (and dangers) if it didn't require a power supply replacement.

I would love to work at an apple store but the closest one is 30 minutes away on a good day- I'd be spending half my salary on gas :eek: 9 bucks an hour sounds a lot- and it is for a high schooler, but with those darned taxes once you get out of the part of your life where your parents basically pay for anything, it's not a huge amount :p
No, working for $9 an hour and having to spend half of that for gas is not worth it. Perhaps Apple will eventually build a store near you, then you can work for them. :)

Well I'll be ****ed and stuffed. Sometimes you get a good case of foot in mouth around here. I guess it's just that I have never seen a DVD-RAM drive without a case.

Until the 10.4.6 update you could use InCrease on Intel Macs and set that up to fold using both cores. I guess you could always go back to 10.4.5 and run that! It'll be really slow on an Intel Mac, btw. My girlfriends 1.25Ghz G4 Mini will do a work unit in 3 - 5 days, and my Intel Core Solo takes about 30 days. Ridiculous.
I've since started using the BOINC client which is a UB, and doing SETI and Einstein@home, since both seem to run well on the Intel. No folding thingie for the BOINC client yet, though, I'm afraid.

That info actually aproximated from the very first tests with the Radeon 9700... i cant remember which site. But even on those tests like if yuo look at the 3d mark scores and results it doesnt even come close to 100% faster than the GF4 Ti

You can get as granular with the analysis as you like I suppose.
I prefer to keep it much simpler.
One guy was cool and the other was not. The words they were speaking were for folks that have already made their computing choices. And the words were mostly for Macaphiles. Those ads aren't going to convert anyone.
99.9% of advertising, especially when a visual medium is utilized, is to evoke an emotional response.
The ads aren't designed to convert-- they're designed to reassure us Mac heads that we've made the right choice and we're the cool ones.
Works for me.

Run: 46 (Clone 203, Gen 0)
Frames Completed: 0, Remaining: 400
Dynamic steps required: 5000000
This work unit was choking the PowerMac G4, which was doing one frame per hour. It would take the Mac seventeen days to finish the unit. How does a G4 user tell the Folding server to not send TINKER units to G4 CPUs? Waiting three weeks for a result, when an x86 system could have the unit done in a few days, is inefficient.
"Seventeen days? Hey, man, I don't wanna rain on your parade, but we're not gonna last seventeen hours. Those things are gonna come in here just like they did before, and they're gonna come in here and they're gonna come in here and they're gonna kill us!" -Private Hudson

Apple are going to be so far behind if they stick with motorola for much longer and don't get a chip like the IBM one soon.
The G4 is an ageing design, still doesn't have a DDR FSB, still can't get the Mhz up to complete with the Athlon (Pentium 4 doesn't count) and unless some miracle happens and motorola bring out an 8 way superscaler G5 with a DDR fsb, altivec and 64bit architecture. Apple are going to be a total laughing stock.
With the AMD hammer coming out in a matter of months, the pentium 4 pushing 3Ghz with a 533Mhz FSB, apple have got to pull something out of the hat next year or none of their Power (and it use the term loosely) Macs will be worth the cost of the components their made out of.
They're already on a "clutching at straws" lineup by going all dual, Do you think that dual 1.25Ghz model can compete with a 2Ghz Athlon ? I don't, not for a minute and that's just now, what about in 6 months time.
I think apple HAVE to have some new cpu from motorola under wraps, that new motherboard is practically wasted on a G4 and we need at least a 1.6 Ghz chip with twice the IPC of the current G4 design just for the next range to compete with PC cpus and be significantly faster than the current range of powermacs.
I'm sticking with apple whatever happens CPU wise but it would be nice if I could one day buy a �1,349 powermac that competes with a �1,000 PC.

some clarification here.
to my knowledge, apple had the 10GB introduced in march 2002 with the scroll wheel and the same thickness as the 5GB. then at macworld of the introduced a touch-wheel 10GB that is slimmer, and the 20GB. maybe the 10GB was always thinner than the 5GB, but i'm pretty sure it went how i just said. please, feel free to correct me.

I try to keep up as much as I can, but I also go through periods of trying to save electricity. I started a couple years ago with my G4, then stopped after a few months, then I ran Folding on both processors of my G5 for 5-6 months last year, then stopped around Christmas, now I'm back at it on my G5 as of last week. I certainly haven't given up the cause, I just keep having spurts of thriftiness. ;)
Luckily I have passed into the top 300 though, so go me!

if you have any questions, ask away!What kind of school group was it?
What did you and others who didn't get stuck do while waiting for those that did get stuck?
What did those who got stuck tell you about the experience later?
Did any of them get interviewed by the media?
Did Apple explain what happened? Did they apologize or make any other nice gestures? Do you think they handled it as well as they could?
Will you ever go back there?
