Hi,

Does anyone knows which is the better -and faster- SGI configuration for
the Alias Poweranimator V8.0?

1. - SGI Indigo2 Extreme, R4400 200 Mhz processor, 128 Mb RAM, 2Gb HDD

or

2. - SGI O2, R5000SC 180 Mhz processor, 128 Mb RAM, 2Gb HDD

 Please don't compare the price, only the speed. (real-time OPenGL
rendering, high resolution rendering speed).

Thank you for help

I am not an expert, but have done quite a bit of research over the past
year.  Between those to system configuration, I believe the Indigo2 is
going to be faster, but I wouldn't stop there.  The Indigo is outdated.  If
you go to the O2 R10000 you are going to be faster.  Also the 02 uses
unified memory architecture, so the more ram, the faster it goes.  I'd go
with the O2 R10000, if I had the money of course.  It's not really the
Hardware that's the problem.  It's the cash it takes to buy the software
that hurts.

So O2 with R10000CPU and 128MB RAM is your best bet for Alias.

One thing, with the O2, you will need more RAM. (at least 64MB more
than an Indigo^2 to do the same things) And O2 RAM is custom stuff
available form SGI and Kingston only (OK, a few other places carry
it...)
Indigo^2 RAM is just the highest-end PC RAM made.

All other things being equal, I'd take the Extreme.  It's been around
for
a longish time (ie, no bugs) and I like the idea of having deticated
Geometry
Processing Hardware instead of just doing everything in a faster CPU
(ie, what
O2 does)

If you want to use any sort of "3D" Paint program (ie Alias
StudioPaint3D or
IFX's Amazon) I would go for the O2 with it's hardware texturing.

I have heard they are about the same, however, because of how the
unified memory architecture works on the 02, if you add memory the
performance will get better. Not so with I2 EX.

The trade off is that textures in O2 memory aren't as fast as those in
dedicated TRAM. At least, that's what they say.

So if you add RAM, you can load more textures into memory. That's it.
But geometry performance, and general CPU performance, is unaffected by
how much RAM you have, so long as you're not paging or swapping
excessively.

PS. I have a friend who has used Alias 8.0 on the 5k and 10k who reports
1.5-2x faster rendering with the R10K O2. For about ~2k I thinks it's
worth it. (150mhz R10K)
