1.8GHz in 2003 - no G5, ever
Here's a quick summary of an article in UK MacUser, issue 09/08/02 (that's right, it isn't even out yet!) - it may be on their web site, haven't checked (can't see it on the front page). Before you read it and think "wow", remember that this is the magazine that cites MOSR as a credible source.
***
Motorola is moving into final testing stages of a new G4 which will run at 1.8GHz, this is the 7457 and is about to be produced in "sample quantities" - if all goes well it should be in production scale quantities by the end of the year allowing Apple to ship it in the first quarter.
(this is already sounding pretty ropey to me).
PPC 7455s running at 1.4GHz are "in production" (no clues to shipping dates).
They are urging caution for announcement at MWSF for the 1.8GHz, but say late Jan is "more likely" (!?).
(Ha, ha, ha, get this)
"Like the 7455, the 7457 is expected to scale more rapidly than earlier G4s and take the range beyond 2GHz."
G4 is to remain mainstay of the desktop for the foreseeable future. [some unspecified] G4 in the future is expected to reach 2.5GHz before being replaced (by GX).
G5 has already debuted, 8560, as an embedded processor. Er, "because Motorola usually rolls out high powered variants, then low-powered ones, and this is a low-powered one it seems there will be no high-powered 85xx" (that's paraphrased, but I can't really make much of the logic involved).
G5 seen as chip for embedded rather than desktop market.
"Sources (they probably mean MOSR) have indicated that [the] G5 may not now feature in Apple's desktop plans, with faster revisions of the G4 taking its place in the company?s pipeline until the debut of the G6 series in late 2004."
***
Last paragraph sounds like utter bollocks to me.

<strong>I've been saying no G5, IBM's power4 core will be the next gen for Apple. The 1.4ghz's are suppose to ship this month, but Mot could have problems shipping them right away so they may are may not be announced.</strong><hr></blockquote>
In other words... GP-UL that Moki has been hinting about as of late... :cool:
Underwriters Laboratories of course!
<strong>did anyone figure out what UL means?</strong><hr></blockquote>
Didn't need to figure it out... Hint: Think of a kind/catagory of aircraft...

Peter Sandon, Senior Processor Architect, Power PC Organization,
IBM Microelectronics IBM is disclosing the technical details of a new 64-bit PowerPC microprocessor designed for desktops and entry-level servers. Based on the award winning Power4 design, this processor is an 8-way superscalar design that fully supports Symmetric MultiProcessing. The processor is further enhanced by a vector processing unit implementing over 160 specialized vector instructions and implements a system interface capable of up to 6.4GB/s.
Emphasis added. It's maybe not the hottest news, but interesting nonetheless. How many instructions does the altivec extension comprise? Are there any other desktop OSs on PowerPC other than MacOSX? AIX maybe?
Got to go get some sleep.

Ah, speculations and coincidences, robbing my sleep... .

ok, but what i don't quite get is that the page is dated Oct 15th. So the site is telling us about a future announcement? seems a little shady. seems like big blue would keep details to a minimum until they actually make the announcement.
(not that i'd complain, i'm praying this is the (near)future of the PowerMac platform)

Why is it shady? Intel and AMD do this sort of thing all the time (revealing future products before officially announcing them). They go as far as telling the media the codenames of future products.

thanks.
<strong>Any techie out there who wouldn't mind quickly explaining what "8-way superscalar" means and what it does?
</strong><hr></blockquote>
It is generally refering to the number of instructions which can be dispatched per clock cycle. The G4 is 4-way, IIRC, and the new Moto G5's are only 2-way. 8-way implies that it could perform twice as fast as the G4 at the same clock rate, ignoring everything else.

Sounds good to me...
Thanks for the information.

And what would it mean if said CPU was clocked at say... 1.6Ghz - 2.0Ghz??? <img src="graemlins/smokin.gif" border="0" alt="[Chilling]" />

GP - UL
this is my best guess: graphic processor - ultra linear
This would be a graphics chipset that has large amounts of cache maybe L3 like seen in the current G4s - but dedicated to a graphics chip...
Next question....
Simple, to the point, and 100% true. In fact, I believe it would be safe to say that it's... *CONFIRMED*.

Well... how 'bout that?
