What, exactly, are you smokin? There is no way Apple would be able to deliver on that pipe dream.

ShnikeJSB said:All I know is, in my case, it is a race of Apple against Dell. It's Dell offering a combination of another 34% off and better screens on their XPS Gen 2's, and Apple releasing new PowerBooks. Whichever happens first, I will buy. It had better be soon, either one, as my TiBook is on its last legs. Apparently, Dell will be replacing the crappy WUXGA LG and Samsung LCD's on the Inspiron XPS Gen 2, and then it will be pretty much ideal, except it needs that 34% off coupon again and it makes it cheaper than Apple's PowerBook with much more/better stuff. COME ON APPLE!!! Bring something out worth paying so much for... And soon... -JB

~loserman~ said:3GHz dual core 970MP's are only found in dreams.
When the dual core 970MP releases it will be at the most 2.2GHz
IBM can't even get the single cores to 3GHZ. What makes anyone even half consider a 3 GHZ dual-core. Remember they are both made in the 90nm process.
Frobozz said:You mean the OS doesn't factor into your decision? That's 75% or more why people on boards like this buy Macs in the first place.
Frobozz said:The rumor sites seem to disagree with you. The consensus is the 970MP starting at 3.0 GHz.
Coincidentally, this is likely why the top of the line PM is 2.7 GHz now. This revision gives Apple the time it needs (6 months?) to get IBM producing 3.0mp's outside of prototype land. In that revision, we'll probably see all the niceties that got cut for this revision: PCI-E, DDR2 667, HT 2.0, Dual Core 970's, and maybe even Blu-Ray.
wdlove said:Sounds as though this is the update that everyone has been looking. So are we talking about October/November time frame?
Frobozz said:I have to believe that Apple is planning the update for one of two timeframes: September/October '05 or January '06. If they can go in October and have enough lead time to deplete existing stock, they'll do it IMHO. But I would say there is no doubt if they miss a fall release (I generalized as October) they'll hit January '06 MWSF.
They might even announce them at MacWorld Paris if they can-- but I tend to believe the 3 to 4 week lead time announcements are left to all but MWSF '06.
Your thoughts?

blitzkrieg79 said:It is clearly visible that the Power4 derived 970 cant be clocked much higher than already it is considering Apple waited almost a year for the latest update and they only got 200MHZ
What? Apple helped IBM to develop the Power5???? Coolthat Apple helped IBM design and develop Power5 along with its derivative from scratch,
thats why maybe it would explain the significant jump in floating point performance of the Power5 (where the highest clocked Power5 beats the highest clocked Itanium2 by over 20% so there is something to brag about considering that the actual Power 5 processor is smaller in size and has a lesser transistor count than Itanium)... My guess is that 970MP is pretty much a Power5 derivative (or maybe a Power4/Power5 mixture) why is it called 970? I have no clue?!?!?
Kaborka said:Ehm - Apple did not get 200Mhz more. The new G5 2.7 ist overclocked like the 2.5 machine was. IBM still builds 2.3 Ghz pieces only.

The basis of Power4 and Power5 is essentialy the same. IBM added an on-die memory controller (like AMD did), on-chip SMP (like Intel's hyperthreading), larger caches and an improved memory subsystem. Floating point performance is the same, [#Ghz * 4] GFLOPs. In praxis Itanium is superior to Power5, which masks much of it's performance drawbacks with gigantic caches.
On-chip SMT and on-die memory-controller will surely find its way into a hypothetical PPC970 successor and add a performance win from 10%-40% in multithreaded applications. But Power5 is still 90nm and one can not expect a PPC970 sucessor be be clocked higher than the current model.
On word to "cell". This thing is nothing a fully featured OS can run on. The Power core is crippled and by far no Power4 or PPC970. And it is virtually impossible that Apple is able to adapt it's OS to cell. This would take years.
Again, Apple is driving down a blind alley with it's PPC970. There is not even hope...

p.s The current Power4+ ist dual-core since years.
First, the 970 @ 2.5 and 2.7 GHz are not overclocked. You are incorrect.Kaborka said:Ehm - Apple did not get 200Mhz more. The new G5 2.7 ist overclocked like the 2.5 machine was. IBM still builds 2.3 Ghz pieces only.

the first batch of Dual 2.5GHz were equipped with overclocked 2.3GHz processor... you believe it or not, des not matter, it is a fact.daveL said:First, the 970 @ 2.5 and 2.7 GHz are not overclocked. You are incorrect.
Second, the Power5 is NOT manufactured on a 90nm process. It's is produced with the older 130nm process:
"POWER5. The new POWER5 microprocessor features 276 million transistors per processor, and is manufactured with IBM's 0.13-micron copper wiring and SOI (Silicon-on-Insulator) technologies. POWER5 defies historic focus on clock speed for performance with unprecedented levels of integration. POWER5 integrates not only multiple microprocessor cores in silicon, but elements of memory and task management that have long been outside the chip." from:

Third, given the above, the remainder of your post has no merit.
Frobozz said:I think it's always prudent to wait until revision B, but in this case I might jump on the bandwagon. My Mac is getting long in the tooth (but it has really kept relevant longer than most of my other Macs.)
Personally, I would be more worried about a liquid cooling unit's long term prospects as opposed to, say, addition of PCI-E, HT 2.0, Dual cores, or faster ram (DDR2 667?).
So, in an ideal world, waiting to revision B of the dual cores would be best. As a side note, I don't think you're looking at people with G5's already in this upcoming revision anyway. It's people like me with a 3, 4, or 5 year old machine that is still in their production workflow. We're getting antsy.
I've considered waiting until the dual 2.7's come in on refurbished status at the Apple store ... but my belief is in the long term viability of a PCI-E bus, coupled with dual core processors. I think I bought my DP Quicksilver in the sweet spot and my gut tells me this new revision will be the next sweet spot for me.
I think saying "we need altivec" and "we need a CPU that need less than 100W" is not really something I would call "involvement". The PPC970 is basicly a crippled Power4 with added Altivec (also crippled compared to G4's implementation) and added power-saving features.blitzkrieg79 said:First off, Apple IS involved in the actual PowerPC research/development (how would IBM exactly know what Apple exactly needs and they attached the Velocity Engine mainly because Apple demanded it)
and from all the reading I recently did it does appear that Apple was involved form the beginning in the parallel development of the mythical 980 processor with Power 5
As far as Power5 vs Itanium2 is concerned, notice I said highest clocked Power5 (1.9GHZ) beats highest clocked Itanium (1.5GHZ) in floating point performance by 20%, of course every processor has drawbacks but you also have to take in to consideration the fact that Power5 is a lot smaller than the Itanium2 chip and yet it delivers threatning performance to Itanium, just like in our world,
As far as Cell is concerned, as a mentioned earlier, Cell is a broad concept, Apple doesnt have to spend years on updating its OS to suit Cells needs,
can ask IBM to develop (if they already didnt do it) a Cell like architecture with Apple in mind
They are. Nobody has ever seen an air-cooled PPC970 faster than 2.3 Ghz.daveL said:First, the 970 @ 2.5 and 2.7 GHz are not overclocked. You are incorrect.
My fault...Second, the Power5 is NOT manufactured on a 90nm process. It's is produced with the older 130nm process:
Air-cooled has nothing to do with anything. I have an air-cooled dual Opteron at a mere 2 GHz; the fans sound like a jet taking off. The 2.5 GHz G5 does not require water cooling; it's water cooled so you can still take a phone call in your office with the system running full tilt. Anyway, at the end of the day, the whole topic is relatively unimportant.Kaborka said:They are. Nobody has ever seen an air-cooled PPC970 faster than 2.3 Ghz.

Rumours. But indeed. IBM develops the PPC9X0YY line for Apple. They don't need such a CPU for their own.
You mix up theoretical and practical performance. Theoretical peaks are (double precision):
Itanium 2 1.6GHz: 6.4GFlops
POWER4/5 1.9GHz: 7.6GFlops (single core performance)
PPC970 2.3Ghz: 9.2GFlops
Opteron 2.6Ghz: 5.2GFlops
Pentium 4 3.8Ghz: 7.6GFlops
In praxis for broad range of scientific applications the ranking is this:
Itanium 2
Power5/Opteron
Power4/Pentium 4
PPC970
Itanium dominates all other machines and shines bright in every floating point intense application.
PPC970 only shines bright in some special cases, where it can fully exploit it's multiply-and-add capabilities (e.g. in LINPACK (TOP500)). SPECfp(rate) numbers low and disqualify this CPU for general numbercruching tasks.
Opteron has the most advanced system topology and can compensate it's peak performance disadvantage especially in multi-CPU configurations.
SPEC numbers for Itanium and Power4/5 are some kind of misleading, because their large caches disort the results to some extend. SPECcpu 2004 will correct this later this year with larger memory footprints.
To sum it up, I have never seen an scientific application where another CPU can beat Itanium 2
Since 4 years (probably more), Apples is developing OS X and it is still not 64bit and kind of beta. How can one expect Apple to adopt OS-X to a completely different architecture. OS X requires a fully featured PPC core. Cell is no replacement. The only thing I could imagine ist a cell DSP card in a Mac.
For IBM Apple has no importance. IBM will never build a special-Mac CPU, far different from their own existing CPUs.
