AMD significantly faster in Rhino than Intel?

[Macpod]

I use both an Intel C2d 2.66ghz and an AMD X2 2.6GHZ at work. When trimming a complex geometry, the AMD system is much faster. both have DDR2 800 memory.

 

I use the Trim command and it seems to run on both cores at first then revert to 50% utilization.

 

this is strange, because the C2d is 10-15% faster when rendering butt he AMD is much much faster[50%] at trimming and splitting...

 

 

any ideas?

 

 

Im asking because im trying to decide between a phenom II and I7 for home use.

Modeling operations and rendering operations are completely different, and therefore are can not be measured in a linear fashion. You need to choose which is more important to you, modeling speed or rendering speed?

Yes, Thats true. But what i really want to know is whether this is just an anomaly or a commonly acknowledged pattern.

 

rendering is less of a concern, I know the i7 will be faster.

 

But modeling seems to be an oddball........I would rather have a faster modeling machine.

 

What i would like to know id whether operations like trimming , splitting, and intersection will be faster on a 3.6GHz Phenom IIx4 or a 3.8Ghz i7 920.
