Thought i’d add a dual core bench
Single 7.621
Multi 4.786987
Dual Core AMD 4400+ X2.
37% speed increase.
Edit double post sorry.
Sweet. Looks like those dual cores are pretty heavy duty.
Single 11.83
Multi 11.92
p3 2.8Ghz 2 gig
Thanks Carthic.
With a bit of overclocking i could get it down to 4.1 at multi, but i wasnt too happy with the stability of the machine at that point.
Hm, here’s my result:
Another AMD Athlon64 X2 4400, 2.2 GHz
2Gig Ram
ASUS AN8-SLI Deluxe
Abit ATI X800XL
After figuring out to NOT use nVidias updated IDE or SMBus drivers this thing is working great. I’m just using the stock XP SP2 drivers for the bus at the moment, do you think that’s why I lag Carthic? The processor seems stable at 2.3 GHz, but why bother. I’ll have to watch the temp with both cores pegged to the limit rendering fancy-pants Mental Ray SSS and final gather to determine if I want to push my luck!

hallo from kiel, another result.
dualhead amd opteron 1.6gh
gforcefx500
2wd raptor 10000rpm
Here is a nifty little program if you are worried about the extra heat from overclocking.
edit Sorry forgot the link 
I should of clarified, the first result was with the CPU at 2.5Ghtz the 2nd with the CPU at 2.7Ghtz (unstable for me 
)
Singele Thread : 22.533
Multi Thread : 22.941010
Multi Threading resulted in 1,8 % speed decrease
*Strange i thought before it recommended to turn it on?
I have p4 3 Ghz 1 gb ram.
How does it count is lower better?
Carthic,
Ah ha! 
An extra 300 MHz on two cores might explain the difference, that’s a good overclock. I notice two opterons get the same increase in performance, I wonder why the multithreading limit is a 37% boost. Does that mean Zbrush runs two threads, one more computationally intensive than the other? Maybe one core manipulates vertex data and the other texture data, hm. When I get home tonight I’ll have to do the test with the CPU monitor running. 
I wonder what the boost is for rendering, I think only bucket rendering, such as in mental ray, really takes advantage of multiple processors/network rendering.
Such complicated stuff! Pixolator is a smarty-pants to take advantage of multithreading, but then we already know he kicks butt. 
Single Threaded= 8.521
Multi Threaded= 5.344

it probably won’t pixelsoul until zb has a 64bit version.
thought I would repost mine since I have way more crap sucking resources now than when I first got this computer just for kicks to see the differences

not bad loss but have at times seen both in the sixes can’t quite seem to break 6.1 in multi but reckon if I overclocked it I could…but this puppy has to last a long long time.
Intel P4 1.9GHz 1GB… - about 23 -… cough cough…
Weird that it’s about as fast as pixelsouls old system with 3GHz…
New system arrives this week… har har har…
