Motorola's MHz = Mega Hurts ?
« on: April 22, 2002, 12:11:34 AM »
There is an interesting article on OSopinion.com concerning the PPC processors.

"What Motorola doesn't want you to know is that obsolescence was planned from the beginning of its involvement in the PowerPC fiasco."

Click here for the article ...

Makes you wonder how fast Motorola could have made the "060" had they continued development like Intel did with the x86.    :-o

Yep... That would probalby have been the better choice, or alternative...
Geesss. I did not knew that about the G3/G4...

This article  is crap. Even I can see that and I'm no HW expert...

I like this paragraph:
 
"Apple and IBM were pleased, but Motorola's M68060
was running circles around both the Pentium and the
PowerPC 601 in a beast called the Amiga. To put it
in perspective, the '040 and '060 Amiga lines actually
used PowerPC chips as text co-processors!"
 
That is not really the way I recall it...:-)

Neither do I!

This fellow who write the article isn´t an expert on his area, I agree totaly with that.
But it seems very impressive if some outsider reads it so why bother ?

All publicity is good publicity isn´t it?

The article reminds me of the diagramed plot line in the Scarlet letter...  it looks something like this:

_/\_

It starts out flat, increases to a point of OMFG and falls rapidly back down to where it started from.

Another example is that of a dying patient.  The pulse starts out as non existant and after a couple plateens of electro shock treatment to get the heart going again the flat line doesn't falter from its course.

Yawn.  I think I'm going to go and do something useful like watching the TeleTubbies with my kids... what did that nu-nu do this time!?  :-D

:pint:

That article is appallingly inaccurate and pretty baseless.

IIRC, the 620 was not even released.

The 601 was the first in the PPC family, and started at 60MHz in the Apple lines. It was fast, the OS was still mainly 68k though, hence emulation slowed the system down. I don't know if Apple ever used the 602, but it was the chip between the 601 and the 603, obviously!

Yes, one wonders where the 68060 would have got to if Apple had used that processor. It would have made faster speeds for sure, maybe up to 200MHz in 1996/1997 time period. But the PPC was much faster than the x86 in 1998.

It is only the recent history of the PPC that it has lost any speed advantage - 1999 onwards in essence when the G4 failed to scale beyond 500MHz and the x86 processors (basically an x86 decoder with RISC core) scales upwards and onwards.

And why? Because Motorola don't care about desktop processors any longer. Embedded is their market. Without the money that Apple is putting into future PPCs, there would be very few upcoming fast processors. As it is, the ones that come out will be solely for Apples use for a long time, we won't see them in the Amiga market.

The article states this:
"The 602 was used in stadium scoreboards, remote-controlled Transformers and the popular Nintendo 64."

The bit about N64 is simply not true, and I imagine most people on this board know this.  Doesn't do much for the reliability of the author.

>620

Waiting for this CPU is similar to "Waiting for Godot"! :( This CPU is another failed Bull (France) project that bring down the company.

There is another mythical PowerPC 615.

Also there is an old PowerPC compatible vendor: Exponential with its failed PowerPC 704 project. The company went under several years ago.

No really.. after reading this article..
who wanst RISC ???
why not just go for x86 ???

Newer x86 compatibles is RISC! Well, sort of anyway...
It uses microcode to emulate missing instructions.
Rather effective, since a program optimized for Pentium, K5, 6x86 and later runs as kinda RISCy, but they are still compatible with older CPU's wich still runs the as CISC. They simply removed some instructions and made others more effective.
Correct me if I'm wrong, but I thinks it is that way...

Beating the dead horse since 2002.

Yeah so there are still stupid persons who think Mhz does matter ... well look at this rc5-64 speeds:

http://n0cgi.distributed.net/speed/query.cgi?cputype=79&cpumhz=2556&recordid=1&contest=rc5&multi=0

Pentium :

Record id | CPU Name | MHz | OS | Client | Speed
8390 | Intel Pentium 4 | 2556 | Windows 2000 | 2.8015 RC5 | 3,644,544

And now the PPC :

http://n0cgi.distributed.net/speed/query.cgi?cputype=99&cpumhz=1600&recordid=1&contest=rc5&multi=0

Record id | CPU Name | MHz | OS | Client | Speed
8437 | Power PC 7450/7455 G4 | 1600 | MacOS X 10.1 | 2.8016 RC5 | 16,991,648

So a 2556 Mhz Pentium proccessor ONLY does 3,644,544 Kkeys/sec , while THE LOWERED MHZ PPC
AT 1600 Mhz , DOES 16,991,648 Kkeys/sec !!
What i can say is that is is like 6 times faser then this stupid Puntium 4.

So F*ck Mhz intel-wintel-lovers...

 :-P

Hmm, that makes one wonder it it wasn't all planned to make Amiga go down.
