Now that Apple is bowing down to Intel, does anyone have any plans to
make a Power PC 970MP Mobo?

IBM, for sure:
they sell server with PowerPC 970 inside.

What machines does IBM presently sell with PowerPC. Last I looked,
after the 43p-150, everything was Power.

In fact, POWER is just a commercial name for high-end PowerPC.
IBM PowerPC 970 based machine that I know are JS-20 blade center:

No. POWER is POWER and PPC is PPC. Blades are a different animal. None
of the Low, Mid, or High end servers use PPC. Blade is a category all
in itself. You can get blade servers with Intel in them - but note you
can't get Pseries boxes with Intel in them either.

For packing density, PPC can have advantages. Simply not used in
standard lineup.


Cheers.

Take a closer look to POWER specifications, please.
POWER was and original architecture from IBM, used in the early RS/6000.
They extended it with POWER2.
Then, IBM, Motorola and Apple developped the PowerPC specification, based
on IBM work on POWER. The first PowerPC, (PPC601) was fully POWER
compatible.
From this point, IBM developped 4 lines of products have been developped
on PowerPC specifications:
- 32 bits embedded PowerPC: was 401, then 403 & 405.
- 32 bits generic PowerPC, as 603, 604, 750, ...
- 64 bits RS/64 PowerPC
- 64 bits POWER.
The two last ones are extended PowerPC. They follow the whole 64 bits
PowerPC specification. RS/64 adds tagged memory access and was mostly used
in AS/400 line of products. POWER3 & POWER4 were most designed for
mainframes, with multicore and hypervisor features.

Nowadays, PowerPC 970 & POWER5 use the same core unit. But POWER5 is
multicore and PPC970 has hypervisor feature disabled (though all
needed registers are still present).
And IBM uses POWER name for _all_ their PowerPC based products.

The difference between POWER & PowerPC is quite the same than between
Athlon XP & Athlon64.

I was talking about one model of the IBM eServer Blade Center.
I said "JS-20 blade is 970 based". I never said _all_ blades are Power
based.
Please try to read before arguing...

OK, I may have missed something here - you are claiming that the
instructions dropped by the PowerPC after the 601 have now been dropped
in POWER? That would be news to me ... common-mode is not needed any
more? It would be news to me if the POWER included the graphics related
functions (I read them as MMX like stuff that Apple wanted) - I can't
find the article right off, but IIRC it was related only to the PowerPC.

I would have to look up the history of 64 bit PowerPC, because PPC
disappeared from the IBM machine line up. At one point, the most
powerfull box RS6K was PPC based - the J50. Yet, the first 64 bit
machines, and all RS6k/Pseries boxes since, don't use PPC. They use POWER.

Here is what IBM told me over the years - they were going to get speed
and performance improvments going to smaller packaging. All there boxes
headed in that direction. Ooops. POWER came back to the forefront
because they could put the servers line back into a performance range
that was competative and PowerPC could not.

That is quite a stretch. Let's see, if the Athlon 64 spec was developed
not by AMD, but by a consortium which included other vendors, and then
broke backwards compatability ..... And that of course completely
ignores the real point - these are two different microprossors and the
POWER vs PowerPC are completely different packaging animals ...

"In fact, POWER is just a commercial name for high-end PowerPC."

In fact, PowerPC is just a commercial name for a low end POWER. It has
failed in it's orginal intent. How long it will remain alive is a good
question. I am sure IBM will milk what it can out of it's investment,
but for the original poster - good luck finding MBs so folks can build
'clone' systems as was done with the G5 stuff. IBM no longer used it in
their main product line, and with Apple dropping it, who is going to
build then next MB we could put in a desktop? Embedded and specialty
devices like the blade server seems to be the only life left in it.
It's a pity, really, but there it is.

Now, as he said POWER is a superset of PowerPC.

Some PowerPC chips, notably the G4 and G5 have a vector processing unit
(Altivec). POWER and most PowerPC implementations do not.

Altivec is not a part of the PowerPC specfication but an add-on.

Yes, well, as he noted, POWER came first, and the first PPC was an
identical instruction set - then PPC dropped some instructions and broke
all sorts of code. To say that the new chipsets are 'based on' the PPC
specification, but are a 'superset' - if that 'superset' is indeed the
instructions that have been there all along - am I the only one that has
a problem with that logic?

Thank you - that was of course what I was trying to remember.

Probably very very long. Most game consoles use PowerPC now.

I see them popping up in printers, too.

And lots of embedded systems. The Motoroal MPC860 and variants (all
with a powerpc core) are much loved in communications applications.

???? I remember reading about the new Xbox hoorah - but as I don't
exactly follow game consoles - in fact I only know of Xbox and PS2, or
maybe if Nintendo is still around? Are any or all of these what you are
referring to?

And I assume these are the embedded models - which would also make sense
to me as having the longest life. I vaguely hear that they are rather
popular (though I hadn't heard of game console use!) - the other models
are the ones that I haven't heard anyone exactly lining up at the door for.

What other game consoles do you know? The three major ones use PowerPC
now (or with the coming incarnation).

The Xbox uses three 2 GHz 64 bit PowerPC chips (presumably G5

It's been in the news for over a year that all consoles switch to
PowerPC. Where have you been hiding? (And can I come?)

Cell isn't just a powerpc, the ppc is just one part of the core.
Have a read of the docs.

Some good articles here

No not G5 but custom powerpc chips. No ooo (out of order) execution.
Basically no branch prediction.

Also cut down the complexity of the core so they could get faster clock
speed.
