rendering benchmarks - mactel vs PPC . . .

[__archiben]

i've been having some lightworks fun . . .

THE FILE
1.3MB compressed. render size: 1400x918 pixels. lightworks photorender settings were all 'best' with all effects on. 'sun', 'ambient' and 'lamps' on, 'camera light' off. realistic sun used with a sample rate of 64 and divergence of 2º. there were 13 window lights and 1 additional sun object (The Dwight Undersun™). the polycount stats for the file are attached as a screenshot. no other apps were running. there was a lot of glass - and therefore reflectance - in the render . . .


THE MACTEL
archicad 10 INT mactel (build 943) on 2.16GHz intel core duo, 2GB ram and 256MB ATI video card + OSX 10.4.7 ...
open 3D window (openGL) - 15 seconds
the render - 10 minutes and 4 seconds


THE QUAD
archicad 10 NZE (build 966) on G5 Quad - 4 x 2.5GHz PowerPC G5, 4.5 GB ram and 256MB nvidia video card + OSX 10.4.7 ...
open 3D window (openGL) - 15 seconds
the render - 26 minutes and 59 seconds


THE DUALIES
archicad 10 NZE (build 966) on G5 Dual - 2 x 2GHz PowerPC G5, 2.5 GB ram and 128MB nvidia video card + OSX 10.4.7 ...
open 3D window (openGL) - 19 seconds
the render - 17 minutes and 30 seconds

archicad 10 NZE (build 817) on G5 Dual - 2 x 2.5GHz PowerPC G5, 2.5 GB ram and 128MB ATI video card + OSX 10.3.9 ...
open 3D window (openGL) - 17 seconds
the render - crashed after 3 minutes and 55 seconds - having already placed the background image upside down!

same machine as above, but upgraded to archicad 10 NZE (build 966)...
open 3D window (openGL) - 17 seconds
the render - 17 minutes and 14 seconds

THE MONGREL
archicad 10 INT (build 966) on 2.16GHz intel core duo, 2GB ram and 256MB ATI video card booted into windows XPpro SP2 ...
open 3D window (openGL) - 24 seconds
the render - 27 minutes and 51 seconds


some of my thoughts and hunches . . .

1. mactel is good.
2. there is something wrong with the quad . . . or something wrong in the way that lightworks address dual-cores . . .
3. boot camp public beta still has a long way to go before the windows hardware drivers are using the chips as efficiently as OSX?

your thoughts?
graphisoft's thoughts?

How could it be 64 against 256, Intel will drive ATI out of business>

I am tempted to by the Macbook and not the pro.
I wonder, is there any difference with an attached cinema display, after all it has only 64MB of RAM.

probably part of the intention?

from those results it's not a bad option. screen sized would put me off though. but...

with the 'integrated graphics' it's not the size so much as how it's being used in conjunction with the main, processor, memory. i too would love to know how 'integrated graphics' performs with a second monitor. i'll try to find out . . .

I would like to know how does the Macbook with am externat monitor since I urgently need to by a new laptop PC compatible. Has any of you experience with this?




I bought RISA 3D ( $5,000), it is fantastic, no more structural engineers for me I wish all architect wold listen and learn ti use it.

mate, I wish you a good luck with extra liability for the structural design done in-house. I prefer to sleep well...

Hear, hear!... How much is the insurance in the U.S. for a person doing structural designs without certification? Does RISA cover it?

[Anonymous]

In the US an Architect License certifies for any structural work. The insurance is comensural with the rest od the fields. One declares how much is the built volume and cost and what aspect are to be covered. Un the context of the rest structural is more per sq ft because the structure is not such a large percentage of the total cost. If one does not do structural soon it will do nothing because building departments are requiring structural for all aspect: from suspended ceilings to equipment mounts and how this efects the entire lateral force capability of the entire structure.
