That depends what PPC model the XBox2 uses. MS won't be using the
highest-end chips available because a single PPC970 chip costs more than
the
entire console's target price. Thus, XBox2 won't have a strong effect on
the high-end PPC market, IMHO.

WinNT was originally ported to PPC but sales were nil and MS dropped the
port. I'm sure XBox2 will revive at least part of that port, but IMHO it
would take a miracle for them to release a complete retail Windows/PPC
again.

From what I know the CPU will be customized by MS to have
x86 calls, therefore no need for porting.
 
One day I looked in c.s.amiga.advocacy and found links to what seemed to be
recent Amiga systems, based on the same PowerPC (PPC) processors that are
used in Apple Macs. I googled a bit more on the topic and found sites that
where selling G3 motherboard/processor combos. Seems these are sold by
official Amiga dealers. It seemed kind of confusing and vague, but very
interesting still.

Will PowerPC G5s and future generation PPC processors become off the
shelf hardware like x86, so that white box vendors could build there own PPC
based systems? How easily can this be done now?

I read, what some consider to be a rumor, that the next XBoX may have up to
three G5 CPUs. If so, looks like MS will be releasing a version of the NT
kernal (or something) to run on this. Maybe this could develop into PPC
systems of some sort running Windows Longhorn? Some say if the XBox goes
with PPC then the price will drop on the high end PPC chips.

Anyone know how a G5 system running Linux or BSD compares to an Opteron,
Xeon or even an Itanium system running Linux or BSD? I have seen a few
benchmarks, but there is ofcourse much controversy over benchmarks,
especially when comparing systems with to many components that cannot be
kept the same, and software not compiled to take advantage of optimizations
etc...

Virginia Tech has built a cluster of dual G5 Apples running OS X that
promises to be one of the fastest super computers in the world. I hear that
a dual G5 will blow the doors off of anything from Intel or AMD. Some seem
to think that Intel will eventualy subside while PPC CPUs will gain market
share. Although I kind of root for AMD Athlong-64/Opteron, it would be nice
to see some G5's in the mix.

Ironicaly, ARM could come out of no where and steal the show.

Apple's OS/X is built on a FreeBSD derivative called Darwin. Performance of
a G5 is comparable to an Opteron, though as each side releases new chips the
performance lead will sway back and forth. There really isn't a significant
difference in MIPS per dollar between x86 and PPC today.

A dual G5 is on par with a dual Opteron. The only reason it may "blow the
doors off" the latter is because dual AMD64 systems aren't cheap and aren't
currently marketed as desktops.
Some seem to think that Intel will eventualy subside while PPC CPUs will
gain market share. Although I kind of root for AMD Athlong-64/Opteron,

As someone recently said here, "hardware is cheap, software is expensive."
People buy hardware to run software, so what hardware is dominant at any
time is a reflection of what popular software runs on. Of course, this is a
vicious cycle, since developers target their software for whatever hardware
is popular.
Ironicaly, ARM could come out of no where and steal the show.

It could, but why build a high-end ARM chip when you can just use a PPC?
ARM is currently popular for low-power devices, but if you want a single
architecture with _existing chips_ scaling from embedded devices to desktops
and servers to supercomputers, PPC is the clear winner.

Interesting. Will the CPU still be PPC-compatible or will it be
x86-only?

I remember there was once a PowerPC chip that was compatible to the
80486, back in the mid-90s.

This is unlikely in the extreme. It's a *gaming console* - one or two
markets removed from the type of hardware that M$ is interested in
running Windows on. Note the absence of any general purpose M$ O/S for
XBox Mk I. However it will probably make an interesting Linux box.

I really hate it when people try to put that trainwreck of an OS, Linux, on
an Xbox. Its silly, pointless, and degrading to the best game machine
available.

Leave the Xbox alone. Its for GAMES! Not bash prompts and kernel reloads.

How is putting Linux on an XboX degrading to the Amiga?

But the current XBox runs NT, doesn't it?

Like the Dreamcast did/does?

I know the Dreamcast ran a stipped down version of Windows CE. I'm not
sure of the Xbox.

You might find this link interesting <http://www.970eval.com/>.

This is an evaluation board, so the functionality is a superset of what you
would see in a commercial board. All of the components should be(come)
available to the enterprising third party. I would expect the Amiga
resurrectionists to latch onto this post haste.

Thanks, that is definitely very interesting. It would be neat to see
this take off. Maybe IBM, Dell, Gateway or other OEMs would build
systems based on this hardware and Apple would sell them OS X licenses.
And of course there would always be Linux PPC.
