IBM PPC 970MP A Reality?

"The higher frequency grade versions of the 970MP consume higher amounts of power than earlier IBM microprocessors do, and that can cause temperature issues."
This is not good. Am I missing something here? It says it will consume more power than ealier IBM processors. How can they put this in a PowerBook if it is consuming even more power than the 970FX?

NEW G5 POWERBOOKS ON TUESDAY!!!
for real though, it should be interesting to hear responses from apple and ibm now that they can't (not to say that they wont) deny the existence of the new iteration of the g5. hopefully we'll see the update move into the Powermacs come WWDC, i still wouldn't hold my breath for a g5 powerbook just yet.

Object-X said:Wow, Quad Dual Core G5s!! They come in Quads? I'm getting one! They probably won't put quads in a Powermac thoughSounds like a Xserve thing.
Well, the 970MP is a single processor with two cores. So its basicly two processors within the case of one.
The current PowerMac has two 970 processors (two G5s). So replace those two 970 processors with two 970MP processors, and you get two processors with two cores each, or the equivilant of 4 processors. Whoohoo
I think the single processor PowerMac will become dual core, and the dual processor PowerMac will become quad.

This is not intended for the PowerBook.
The 970MP will go in PowerMacs and the other desktops. The high frequency grade versions mentioned will go in the fastest PowerMac (with WATER COOLING, remember?).
PowerBooks will get single core G5's. Desktops dual core.

The thermal diodes in the 970MP will be a good way to cool and keep cool the Powerbook G5 and dual core Powerbook G5 when they arrive. Not saying the dual core pbook G5 is immediate upon us. Also, I would think if IBM is smart they would have a notebook dual core chip in the works as well as we speak that was being developed along side the 970MP and GX.
We now have confirmation from IBM that the 970MP does exist, as well as a new CHUD utility that has support for 4 cores.
The question is: Is this enough for us to conclude that we'll see dual-core dual-proc Macs in the next few months, or is it still a long way off?

Could be a lot of interesting happenings coming next month, it's been quite awhile since we've had a big month or two for Apple.
Tiger would be a happy camper on this type of chip, due to the improved SMP capabilities.
An across the board switch to dual cores in the G5 lineup would be a major performace change, even if the clock speeds stay the same -- but what is the chance of Steve making a leap like that?

do dual core g5's mean that single core 2.5 ghz g5's get cheaper and more available for imac's? or are that independent issues and the single core g5's remain too expensive for imacs?

Still a heat related issue with the 2.5GHz 970FX, it has localized hot spots that require water cooling in order to draw heat away from it quick enough to prevent thermal death.andiwm2003 said:
So it's a problem that isn't related to cost, the iMacs need processors that meet either the notebook or XServe thermal specifications.
The PowerMacs have always pushed the limit and used CPUs that run far hotter than anything else in the Apple lineup. Look how long it was between the time the PowerMac G4 had 1.42 GHz chips and the notebooks finally caught up.
I have a bad feeling about IBM supplying these chips. Can you imagine how hard it may be to make these chips.
I predict major back logs.

I think this definitely means the next rev will have dual-core processors. This is what Apple has been waiting for and why the PowerMacs haven't been updated in so long. If this was still 7-8 months off (after the next rev), those CHUD tools wouldn't have appeared so soon. And Apple never waits that long to put the latest tech in their machines.Chaszmyr said:

You'd have to have a cooler running single-core G5 if you want to put a 2.5GHz processor in an iMac. It has already been rumored that the next iMac revision will use a 2GHz G5 (and I think that is about right for the time being, but what happens late this year or early next year who knows for sure).
As far as a dual-core iMac, I'd say we might see something like that in mid or late 2006 (say, eighteen months from now).
As for the PowerBook, I suspect that we might see one more revision using Freescale's MPC7448 (a faster and cooler running version of the current G4). That chip might scale to beyond 2GHz and it uses far less power than any known G5. In fact, it uses significantly less power per-MHz that the G4-variety that is in the current PowerBook.
From the sounds of things these 970MP chips sound very hot. In fact I would not be suprised if the chip is initially shipped with each core running at 2Ghz. These chips will also be considerably more expensive than the single core variants. I think people are gettting over excited about this, sure it's a great thing but it's not our Rossetta stone to performance. If you think about it even with two single cores on a Dual Processor system we are not seeing close to it's real potential with Mac OSX of today and most of the Applications on the market. If most apps allready don't make use of Dual Processor what makes you people think that having four Cores would make a substantial difference? especially if Dual Core chips are clocked slower than single core variants.
Both AMD and Intel have stated that Dual Core will initially be clocked slower than single core variants. I would assume the same for IBM considering that the 970FX is allready maxed at 2.5Ghz and requires liquid cooling and 970GX would at best run at 3Ghz Max but probably still be as hot as a single 2.5Ghz 970FX. So considering how hot single cored variants are I find it unlikely that they will be able to sandwich two 3Ghz cores on one chip. So performance could be a wash for the first generation of Dual Core chips versus Dual Processor Single cored systems if we have 3Ghz single cored variants available while Dual Core chips are only clocked at 2.0-2.5GHz max.
I don't think we will see the 970MP shipping in a mac untill the last calendar quarter of the year. Even then I would not be surprised if it only ships in Xserve or may be offered in a top of the line PowerMac Configuration. Remember both Intel and AMD plan to ship their first Dual Core chips as high end Server and workstation Solutions.

OUCH...
Remember, all the next gen consoles are using IBM chips as well.
XBox 2: Custom tri-core high-clocked low-efficiency PowerPC processor. 3 cores, 3 GHz, 2 calculations per GHz. There will be tons of these shipped.
Nintendo Revolution: Unknown IBM PowerPC processor.
Sony: Cell processor includes a PowerPC core.
Apple: PowerPCs in every system they sell.
IBM has their hands full...
