From MOSR

Along with the long-awaited Mac OS X Server 2.0, new PowerMac G4 Servers are expected to be quietly introduced at Apple's Worldwide Developer Conference ten days hence. They will likely be available in 533, Dual 533, and 733MHz configurations with 256, 384, or 512MB of SDRAM.
* The long-rumored revision to the PowerMac G4 2001 line which would include dual-processor versions of the 667 and 733MHz PowerPC 7450-powered high-end models has apparently been held back so long due to issues both with Apple's latest motherboards and the PPC 7450 itself. Reportedly, both are experiencing stability and performance issues in multiprocessor 7450 configurations; this could be related to the quiet rumor that the 7450 is not fully compliant with the MERSI multiprocessing communications standard, despite denials from Motorola sources that this is the case.
* Despite the setbacks, Apple plans to introduce dual-processor 7450-based PowerMacs well before Macworld July, most likely in early June if no new problems are discovered.
* At Macworld New York in July, Apple has placed its bets on the introduction of quad-processor options for at least the PowerPC 7410 (at up to 600MHz), dual processor 7450 configurations up to 866MHz, and single-processor models at 933MHz and 1GHz. With a little luck, Apple will have addressed the multiprocessing issues with the 7450 and could have quad-processors right up to 866MHz.
* Later in the year, most likely at the end of August or early September, the 933MHz and 1GHz PowerMac G4s will go dual-processor and closer to year-end, quad-processor. In early 2002, 1.1-1.3GHz PowerPC 7460 Apollo processors will take over and bring combined processing power of up to 5.2GHz....if we're lucky.

I hope this is true. I sure could use a quad G4 . Which products do you think will come out and which ones do you want?

If it comes from MOSR and Ryan it most likely is complete BULL!

[mac freak]

Actually, MOSR has been pretty accurate lately.

But this... is...
wishful thinking...

Or maybe not?
I could use a quad 1.3 GHz Apollo G4 next year!

Be Happy.

Enough Ryan bashing already. christ, it's a rumor site.

If they come out with a quad 800, I might have to consider replacing my dual 550.
Should be able to bump an 800 to 850 or 900(or whatever works with the bus speed).
I want more power...

i dont get it

"7450 is not fully compliant with the MERSI multiprocessing communications standard, despite denials from Motorola sources that this is the case. "

The Duals will not be 7450s they will be L3 cacheless 7440s

Trust me I know .

And just HOW do you know?

Also, what's the real-world impact of 7440s vs. 7450s?

[Misha]

Actually, Cipher, the icicles report was in reference to the designed plastics... you know, flower power, blue dalmatian... he was right on that part...

[satchmo]

There is a difference between a rumor and pure fabrication.
A rumor is based on information supplied by sources and sightings.

I wonder if MOSR or AppleInsider "rumors" are based on anything other than a wish list of a particular individual or to just stir up the pot.

It's fun to speculate, but as in most cases these sites only leave you disappointed as they hype up things that don't exist.

It was a joke

It just shows my general attitude towards his credibility (I know, I know, don't tell me "he's been fairly accurate lately")...

Just wanted to post something. Have heard from pretty reliable source that here in Europe the new packages have been printed for the newest Mac, and all this person could tell me was that "G4" DOES NOT appear on the package?!
Is there going to be a "G5" on the market inside of five weeks?! Or is somebody playing jokes?!

Was also told that Cube package production has been halted.

[SpeedRacer]

Actually there's some pretty sweet rumors swirling around on the AppleInsider "Future Hardware" chat forum regarding future PowerMac towers from a reliable source utilizing seeded hardware that i am much more inclined to believe than anything coming out of MOSR.

If you can ever access the boards, it's a pretty good thread - ex: Cube-inspired G4 casings, 900+mHz processors, etc.

MOSR is bunk.

Stupid technical question, but what would be the advantage of quad processors? If so many of today's apps don't even take advantage of duals, is there any near-term benefit? Or do apps (and OS X) which do take advantage of dual processors also automatically recognize and utilize quads? (In that case, one would assume that all apps moving to Carbon and Cocoa would work.)

And yikes, but what kind of work are y'all doing that you would use quad 866MHz processors?! I can barely keep up with my DP450!

Mac OS X takes care of it automatically. Programs dont have to be MP aware in OS X. OS 9 is another story .

Thanks, xyber233, I wondered if that was the case. I assumed that if an app was not MP aware the OS would assign it to one processor and use the other(s) for everything else. Perhaps when a few more of my apps are Carbonized and I don't spend 95 percent of my time in Classic this will make more sense.

Back on the topic, I'm not sure I'm thrilled with the G4 case revision rumors I've been seeing. A Cube-inspired silver case in clear plastic would be nice, but a metal box is so... 8100.

[rambo47]

Ha! MOSR is doing some back-pedaling on the thought of quad-processor Power Macs. Today's update seems to say, "Not yet. Problems with the current G4's optimumization as far as MERSI goes." Who gave Meader the reality check?

Actually applications must be multi-threaded to use two processors at the same time in OS X. Applications that are only one thread can therefore only run on one processor.

No, the environment they run in that allocates processing time is multithreaded so the apps need not worry.

Speaking of rumors, I heard that there's a shortage of water at Evian.

Anyway, a quad G4? Likely not. I did hear rumors about dual ghz machines to take the spotlight at MacWorld expo. I heard that the popular Photoshop showdown showed that this machine ran as fast as a "5ghz" Pentium 4.

Along the other misguided pipelines is that the Titanium will be bumped up to 733mhz, and a new battery that is supposed to last two hours longer.

Of course, this is what happens when you drink a bottle of Evian water at the Genius bar.

Anyone who actually thought these were even real rumors must have waited too long at the opening of the Apple Store. But, it's not that bad to dream, is it now?

From News.com

The new chip, dubbed PowerPC 7440, was announced along with a flurry of other new
networking-oriented chips at the Motorola semiconductor product sector's Smart Networks
Developers Forum in New Orleans on Monday.

The new PowerPC chip is a lower-power version of the company's PowerPC 7450 processor, now
used in Apple Computer's Macintosh desktops. While Motorola supplies a large number of
processors to Apple, the chipmaker derives the majority of its business from the
networking-equipment market, where its chips are used in a wide range of products.

In addition to being less power
hungry, the new PowerPC 7440
will be physically smaller than
the PowerPC 7450. This will
help the 7440 chip fit better into
the tight confines of networking
equipment, such as network
routers.

The 7440 chip offers lower
voltage--1.5V, versus the 7450's
1.8V--resulting in lower average
power consumption: about 11
watts at 600MHz vs. the 7450's
14 watts at 533MHz. The 7440's
smaller size will come from the
elimination of a level 3 cache,
which Motorola says is not
needed for networking.

This is not true. Here's the MP situation is OS X.

Processes (applications) are spread amongst the processors, as are threads.

If a single application is not threaded, it will use, at most, a single processor. HOWEVER, it still might perform better than a similar app on OS 9, because low-level system processes (Darwin) can be handled by another processor, allowing the application to truly use an entire processor, not share it with system processes.

Also, multiple processor typically equals larger caches (1 for each processor). If Darwin currently uses processor affinity, then you can get
some huge speed improvements if you get into a situation where the cache is exhausted on a single processor system due to task switching amongst apps and Darwin. With MP systems and processor affinity, more critical code can stay in the cache.

There are real world examples of Linux MP systems performing better than 2x due to this situation.

it good that we all get so excited about new machines. That whats so cool about the mac. My friend has a PC And he hates to upgrade his machine. HArdware problems stuff not working right. I know it does happen with apple but we dont get bumed out by it we know it fixable. All I can say is what ever comes out at MWNY is going to be great as for evian I dont know I could careless I dont drink it. Why can't the the mac rumors be as true to to say the gas prices in the U.S. every night on the news A new rumor gas prices to go up. ^%&$#$!. And they Do!
Oh well I stil love apple.
