    What would you expect from this? I would expect a slight decrease in performance - just as you mentioned.

    Certainly, the limiting factor in my system is the processor speed, the graphics card processor doesnt get anywhere near maxed out.

    A slight decrease, if any, is exactly what I would expect. My suggestion was to msmanor, since he's working on performance theory in a lab - presumably a classroom.

    I've ran this benchmark so many times and 2d performance is almost always based only on cpu speed. Fastest clock per core. I get 12 minutes on 4gb ram in 32 bit xp pro with autocad 2008 on fx1400,fx1800 and fx3800 (which burnt itself out after 15 benchmark trials).
    Buy a Pentium D 3.7GHz and Sata 2 hard drive (must) an Geforce card will do the trick jsut fine. No need for z400 or anything special for 2d application. 3d rendering is a different story.

    after reading all the posts.. is it better to have a lower or higher single loop time.. i see all this data but i don't understand what is considered good or bad.

    Single Loop Time = 45

    I ran this benchmark because I just built this PC, & it doesn't seem like it's performing the way that it should. Maybe it's just in my head. But I was wondering if anyone could help me out with my results. Are these results appropriate for the hardware that I have? Also, does anyone have any personal advice (and/or links, etc..) for speeding up autocad in 3D, or 2D? What should be set for 3D performance settings in Acad? Thanks!

    i think your 2.67 is the limiting factor there.

    I agree. Autocad doesn't care how many cores you have, it just likes them to be running fast.

    My work purchased a E5502 Xeon system (1.86Ghz) for me even after I told them it wasn't powerful enough for what I'd be using it for. After being right I pulled the Fx1800 from the new machine and stuck it in the old 3.2Ghz single core machine. Ran far better. Xeon machine is lying behind me unused.

    I just dropped an overclocked HD4870 1Gb card into my machine at home. I'll run the test again to compare results I posted above, but I doubt there'll be much difference.

    Question Re: Autocad Benchmark using Cadalyst 2008 - Results

    Thanks for the info guys

    My Asus mobo actually comes with a couple overclocking profiles for the i7 920. I've got it set to run at 3.2GHz at the moment. It seems to be entirely stable, and a bit faster. I have little overclocking knowledge or experience, so I would try to increase it to a 3.8 manually, if I knew how.

    Does anyone know if it would have any effect if I disabled the 4 virtual cores (the hyperthreading, i think?) Would that increase, decrease, or have no effect on Acad?
