my SGI o2 smoked my PowerMac G4 933


(PowerMacG4) #1

I tried rendering some stuff from this dude’s site
http://www.cartsys.com/blenderology/home.html
the basement shot from his gallery
My SGI box ran right through it took about 3 minutes, My powermac, well I ate dinner, render it on my o2 5 times. Then I finally killed the render job about 3 quarters the way. the PowerMac version needs to be worked on.
But when it came to controlling the wire frames the PowerMac Rocked but the SGI o2 was too slow responding.
I might just buy that SGI Indigo2.
Or build a PC.
Wheres the old Blender benchmark render file?

I downloaded the basement2.blend to try on my PowerBook G4 550, there weren’t any textures on the table or monitor, so I added some of my own.
This is the render time (background rendering only):
‘[localhost:~] michaelv% blenderpublisher -b Render/blends/basement2.blend -f 1
Saved: /Users/michaelv/Desktop/basement.jpg0001 Time: 01:40.96’
I guess my PowerBook blows your o2 away 8)
P.S. I also bumped the OSA to 8 and the Quality to 100% the render size is the default that was set on download of the .blend.
Nice site!

wild I did a background render this time.
[localhost:~/Documents/blender] james% blendercreator -b basement2.blend -f 1
I did it in
Saved: /render/0001 Time: 00:31.64 (1.25)

That site is a leftover of when there was a lot of SGI users using Blender. But when NaN went Bankrupt most of them switch to Lightwave 3d. Major changes in the irc caht rooms also.
One of the SGI guys did a beautiful pic of a o2 that I’m still looking for.

Background rendering my PowerMac rocks, but when I display it, its a dog.

I have the same problem, thats why I background render most everything. I know what I want fixed.

Its said when a 180Mhz SGI box can render faster then a PowerMac G4 933 when it comes to display rendering. Background rendering on the SGI took 2 1/2 minutes but to 31 seconds on the Mac.

I wonder if the graphics rendering for Blender is coded to make use of the Altivec feature of the G4 processor?

If I’m not mistaken, the wireframes (and everything you do in the modeling window) are handled by the graphics card, while the rendering is a factor of raw CPU speed.

I have the old blenchmark file (blacksmith.blend) - it’s 1.2MB compressed. If anyone can receive 1.2MB e-mails, or has an ftp address where I can upload it, I will.

Hi overextrude,

here`s a link to the"bench mark" speeds that were
posted at the old-old NaN site,:
