I've made a first performance test with my new system. It might perhaps help PIII users, as I also provide the result for my older PIII system.
New System:
P4 3GHz HT 800MHz FSB
1GB RAM
Geforce 5200FX 128MB
Old System:
PIII 667MHz
512MB RAM
Geforce 2 GTS 32MB
The test is for redefining an apartment group which is inserted 30 times in a multistorey building. None of the systems needed swap for the task, as it fitted in 300MB
PIII - 12min 05sec
P4 - 3min 00sec
Since this P4 supports HT (hyperthreading), I repeated the test but now with PovRay raytracing a scene in parallel while Revit was redefining the group. This time the result for the group redefinition was:
P4 (Revit+PovRay) - 4min 29 sec.
Note about HT: The P4 has just one FP core, which is shared by the two logical processors. If the other application was not PovRay but a non-FP task, I guess the result would have been better. I'll test it someday. It's cool to see two processor meters in the Windows XP task manager 8) It seems Revit is not multithreaded, as it will always run on one processor only.
Regarding Revit usability, the P4 runs smoother, of course, although there're still some "freezes" when working in big projects (less noticeable than in the PIII, of course). The conclusion is that there's still no "perfect" processor for Revit, although the P4 may allow me to finish a project which could have been become unmanageable by my older PIII. And, btw, the 5200FX is a lot faster than the 2GTS. I can now drag the multistorey in shaded 3D much more smoother than with the 2GTS.
Also, some people say Intel's HT is a very bad design. I'm happy with my new system, but I don't know HT details enough to say that I recommend it or not to other users. I think the time will tell me whether I would have been happier with a non-HT Pentium or not.
