Got my new dual 2.3 ghz from the apple store yesterday.
It came with OS X 10.4 pre installed, and I must say that I am very impressed.
I have installed Lightwave 8.2.1 on it and I have not have any problems.
I've order 4 Gigs of ram and will be installing it tomorrow.
I will run some test and benchmarks and will post.
For all that it's worth, I ran the bench mark of the teapots on it with the 512 of ram that it cam with and it rendered it in 29.2 sec.
:cool:

have you also worked with other things that have given people fits over the past year or so, like graph editor, etc? and also had no problms, or haven't you had a chance to get that deeply into it yet?

Wow! My old dual 2GHz G5 with 2.5 GB took 92 seconds. Did you render the scene without any changes to its settings?

29 secs

Wow that is fast! My Dual Opteron takes 79 seconds to do that one!

Just to check the scene specs:

30 reflective blue Teapots
640x480
9 Pass AA
Depth of Field
Trace Reflections and Shadows on
Ray recursion Limit 4
1 Segment

I think my scene is the one of the Lightwave 7 Content as I did not update my content dir when I put Lightwave 8 on but I would assume its the same.

Is the new 2.3 an architectural change from the 2GHz G5 or just a speed bump?

Is it possible that LW is taking even *some* advantage of the 64-bit Tiger OS?

Sorry - I don't believe those figures. How can a 30% jump in processor speed generate a 300% increase in render speed...?

Can we see some other benchmarks please?

Sorry guys,
I was running my own benchmark against my old G5 dual 1.8 Ghz with 2 GB ram
I've change the rendering to:
Antialiasing: PLD 2-pass
Reconstruction Filter: Mitchell

G5 Dual 1.8 Ghz / 2 GB ram: 34.9 sec
G5 Dual 2.3 Ghz / 512 ram: 29.2 sec

I Apologize for the mistake.
I will run the bench mark tonight at the regular setting and will post.
:(

Dual 2.0 G5 2.5 Gig of RAM OSX 10.3.8

Original scene: 89 sec

Twisted settings like yours: 28.3 sec


Try changing the n of threads to 2. Standard it was set to 4. For this scene, 2 works the best.

OK, here are the test:
OSX 10.4 Dual G5 2.3 MHz / 4.5 Gb Ram
Original Tea-pot scene: 78.7 sec
with my Twisted setting: 24.7 :)

Well, that's about 15% speed increase over a my machine. Just as the numbers predict.

2 x 2.0 = 4.0 Ghz = 100%
2 x 2.3 = 4.6 Ghz = 115%


89 seconds = 100%
78,7 seconds = 113%

Have you set the n of threads to 2 instead of 4? Maybe that can make up the 2 lost %

4.5 GB RAM vs 2.5 GB in my machine doesn't seem to make a difference.. But this scene is not very RAM intensive.

Apps that will benifit are AfterFX, Motion and Combustion etc.. (also Photoshop, up to 4 GB. I've read interresting material about that. 2 -> 4 Gb = double in speed. 4 -> 8 Gb adds only a 4 or 5% speed increase. all this for 600MB files or larger)

I just got a 2.3 as well with 2.5 gigs in and its wayyy faster than my dual 533 g4.

FYI though, i also put in an ati X800 and its got a really annoying issue with openGL where it has a lot of artifacts, its really fast but buggy right now ( i assume/hope apple/ati/newtek will solve this issue quickly).
