Hyperthreading

Does Autocad 2002, 2004, ADT2004, Vizrender, Chief Architect,
or any program on WINXP
take advantage of the hyperthreading on a PIV 3.06 processor?
What about Dual processors?


Thanks

I believe it depends on the application. Even within AutoCAD, I'm not sure
it takes full advantage of hyperthreading in and of itself. HOWEVER, if you
multitask, you'll notice the benefits of hyperthreading/dual processors.
VIZ Render does take advantage of hyperthreading, you'll notice this when
you render (you always notice how little CPU you have when you render).
Photoshop is multithreaded, as are most rendering programs (VIZ, MAX, Maya,
etc...but not necessarily all).

go to Google and type in 'AutoCAD' and 'multithreaded' and enjoy. For
kicks, you can also type in just multithreaded and learn lots that way, too.

Thanks for the help,

So are you saying that as long as I'm running WindowsXP it will take
advantage of hyperthreading when I'm using two or more applications, even if
those applications themselves aren't hyperthread/dual aware. For example I
could begin a rendering and then switch to outlook and send e-mail while I'm
waiting?
Is it a noticable difference? We don't usually do complex renderings that
run for a long time, but maybe we would.
How does Hyperthreading compare to actual dual processors?

I'm trying to decide between PIV2.8 and PiV3.06HT. Its about $190 diff.

Thanks,
Larry

You should notice a difference, but with rendering, it'll peg "both" CPUs to
the full...as rendering is a very CPU intensive processes. It'll just take
less time. For only $200, I'd go for the 3.06HT... but make sure that the
motherboard you're getting supports HT (it should if you're getting your
stuff from a reputable vendor).

if you get a dual P4, and money is ok, then you will be getting the Xeon,
and that is a much faster P4 then the regular P4 single processor setup.

you will be happier in the long run.

I have dual P3 1.3 and it rarely ever gets beyond 50% usage on either one,
usually
both top out together at 50%.

It is not as fast as I would like, and I think there is not a processor made
yet that is
fast enough. Fast enough for me is one that is instantaneous.

Any application that can take advantage of dual processors (ADT,
AutoCAD 2004, VIZ, and Windows XP itself) will take advantage of
Hyperthreading, just as they will take advantage of dual processors.

How well they do is largely a function of what you are doing with
them.

I've got a Dual 2ghz Xeon machine and I decided to do a test to see how much
more speed I was getting out of the hyperthreading. I ran several tests
using 3D Studio Viz that had a lot of radiosity calculations and from what I
can tell the hyperthreading actually slows down my machine. Can anyone
confirm this?

It could be a definate possibility. Hyperthreading does slow down some
programs. Not sure about that one though...

With the latest service pack and post SP-1 fixes?

And have you upgraded your system's BIOS lately?

The system BIOS is the original one.

Does anyone know of a good benchmark program that will test a dual processor
machine, and is free?

Look for an update, especially if the motherboard was one of the fist
ones to support HT.

The best benchmarks that test dual processors are 3ds max rendering
tests, because they stress the CPU more than anything. Discreet ships
3ds max with a couple of benchmark files on the CD

Thanks Matt I'll look for a BIOS update.
