Multiple core usage

Can anyone explain to me why Autocad does not utilize the power of multiple core computers while working on the program? It only uses a single processor core!

Basically this: 


My PC suppliers recommend high clock speed dual core processors for AutoCAD for this reason. The problem I am now finding is dual core processors are starting to get fazed out with only quad core being the norm. We don't have any quad core PC's right now but soon we will have to replace them. How does high clock speed quad core processors  compare with dual core in AutoCAD?

We do have 2 early single core Pentium 4 computers and these are in many cases faster than our more recent dual cores.


AutoDesk need to look at this.

I think the variable you're looking for is called whipthread, look up it's settings to suit your purposes.

An i7 series quad core should beat the pants off of any Pentium series processor.  Not that they actually *had* pants, more Donald Duck-ish, wandering around half dressed...


Remember you are dealing with a system, not just a single component.  You could have the top of the line i7 processer but that will do no good if you are using an old IDE hard drive.  Not saying that you have to fork out for RAID, hex-core processors, etc.  This is why computers made from good but not bleeding-edge components appear to work so well, since they are not being bottlenecked by one or more of the other components.

If you are going to fly by the seat of your pants, expect friction burns.
Adopt. Adapt. Overcome. Or be overcome.
A good question will be halfway to a good answer.
