I found this (http://207.172.16.150/cubed/PPCSALESFACT.pdf) on a macpage (http://forums.macnn.com/).
And before somone asks, no it's probably not reliable. But if it is...

Due to the company wide NDA I'm under I signed as an inclusion to my contract, I have to be careful what I say:
I can say however, that we had a visit from the Motorola reps, with the basis of thier presentation being a powerpoint slide show containing the information in that .pdf.... perhaps I shouldn't say more.
But an assumption can be made that the information in that .pdf is "not wrong".

Interesting :-D

It almost seems like Apple is getting some of the predated MPC7457 'L' Spec in their latest Power Macs running at 1.25 GHz. The weird thing is Apple is not even listed as a vendor on page 5. Well I can imagine we'll find out exactly what Motorola is up to soon enough!
-
Sigh.. oh well it's back to hoping and dreaming then.
Hmm... haven't I been there before? ;-)
-
Hmmm. I was more interested in the MPC7451/55/57 Pin compatible @ 2+ GHz
That sounds like a nice upgrade for AmigaOne boards in the future. And I must say I'm not completely sure what the G4+ is all about.
-
They should finally suport DDR.
-
I read something about this somewhere else... can't remember where, but the gist of it was that the G4+ should have been the G5, but they decided to scrap RD and just improve on the present design instead.
This is nothing new. in the x86 world, they've been doing it for years. If you look at it logically though, this is the clearly the easiest transition into 64 bit PPC planned by IBM.
a 2.4 ghz G4 would definately put PPC back in the game.. if it were here NOW. IBM and Motorola need to step things up if they plan to stay in the CPU market.

YEAH MAN! WE WANT THE BEST PROCESSING POWER AND ALOT OF IT AND UPGRADABLE WITH HEFTY REBATES AND THAT IT HAVE SATTELITE CAMERAS TO SCAN AND ZOOM AROUND THE GLOBE AND THAT IT COMES WITH A COMPLEMENTARY BONG WITH A FAT SACK OF AMSTERDAM SKNUNK #1! WHACHYALL GOTTA SAY TO THAT? :-P :-? :-D :-D :-( :-) ;-) :-P

This sounds pretty interesting.
Also take a look at the list with reference hardware/chipset design companies.
http://www.artismicro.com/index.html (with board names like A-3000, A-5000 etc. :-)
Marwell (couldn't find a website).

Didn't see MAI there, which surprised me a bit.

As I understand it, the 5th Generation of PowerPC ("G5") will have a different core archictecture to the previous Generations. In English that means code for PPC isn't going to run on G5 Cores. They need new compilers etc - look out for the term e500...

Here is the website of Marwell Semiconductor:
(Gigabit Switch IC).
Marwell Semiconductor (http://www.marvell.com/noflash.jsp)
I saw the same document from Motorola website.
Unfortunately I cann't find it now. Perhaps Motorola pull the "confidential" document from their website.
The result of embedded benchmark is correct.

>MAI Logic not present
Because the main target of the CPU is "Network IC" vendors, and MAI Logic only create chipset for Desktop computers, not Network equipments.
I am afraid that the future G4+ (or 7470), will be targeted at embedded / Network applications, not desktop.
Another link (see October 30, 2002 rumor):
Mac OS Rumors (http://www.macosrumors.com/index.php?view=recent)
From DSLreports.com:
DSLReports.com (http://www.dslreports.com/forum/remark,4909643~root=macdsl~mode=flat)
If the document is a fake, some hackers must be penetrating Motorola website and post the fake document on their website.

That sucks!
Just as us Amigans are getting our G3s and G4s, the G5 has to come along and ruin everything!
Just as we were all catching up with the latest technology for our Amigas, this happens!
Arghh! :-x

BTW, that Mac page you gave sucked!
Nowhere near as good as Amiga.org! :-D

Found this on www.cebit.de
tecCHANNEL.de, 10.02.2003) Motorola Inc. announced two new additions to its roster of processors for the networking and telecommunications industry that consume less power at faster clock speeds than previous generations of Motorola processors, the company said Monday.
The MPC7457 and MPC7447 use the PowerPC instruction set, first developed by IBM Corp. The two chips are available at clock speeds up to 1.3GHz, an improvement over the older 7455 chips that ran at 1GHz, said Glenn Beck, marketing manager for the computing products systems division of Motorola Semiconductor.
The new chips consume only 13 to 15 watts of power at 1.3GHz, and at 1GHz, will consume between 8 and 10 watts, Beck said. The 1GHz 7455 chip consumed 18 watts of power, he said. This allows the 7457 and 7447 to be used in even smaller versions of the networking and medical imaging equipment in which they are currently used, he said.
Older processors from the Schaumburg, Illinois, company are commonly found in control plane devices in corporate networks, Beck said. The control plane acts to direct traffic within a router, taking incoming data and deciding where to send it. The newest processors will be used in those applications, and also in storage devices, he said.
Motorola's chip designers also added 256K bytes of L2 cache onto the chips, which allows frequently accessed data to be stored closer to the processor, improving performance. The 7457 and 7447 are practically identical, except for the support for additional L3 cache storage on the 7457, which makes the 7457 backwards-compatible with earlier 745x processors, Beck said.
Another key to the performance of the new processors is Motorola's AltiVec technology, Beck said. Designed as instruction set extensions to the PowerPC architecture, AltiVec allows a processor to execute multiple units of data with a single instruction, as opposed to conventional processors that process one unit of data per instruction, he said.
As part of Monday's announcement, Motorola is releasing new design tools and code libraries for developers working with AltiVec. System developers will be able to find frequently used pieces of code that they can integrate into their products, Beck said. (IDG)

(Note, thats 1.3Ghz without factory overclocking, the 7455 "only" naturally scales to 1Ghz. My guess would be that the 7457 in it's current state would "scale" to aprox. 1.8Ghz.)
