Rebuild time comparison - volunteers wanted for 5 mins

In my quest to find out how much machine specs can improve rebuild speeds I thought I would make a challenging part and see if anyone would be interested in comparing rebuild times.

 

Under the sweep edit sketch5 and change the dimension of 30 to 40.  See how long it takes to rebuild after you press finish sketch.

 

My machine takes 24 seconds in both 2011 & 2012.

 

Specs are

Windows XP64

Duo Core E8400 3.0 GHz

8Gb ram

Quadro FX 570 card.

 

Thanks.

Thanks guys, the I5 has a similar speed so maybe win7 is afactor there, but maybe its cache or something else as well.

 

I just over clocked to 3.41Ghz and am at 19 sec now.

Don't forget that IV only uses one core. My quad core basically runs IV at 1/4 strength (3.1/4~750Mhz).  I assume a "Duo Core" is dual, that means your running about twice as fast as me, at least as far as rebuilding in IV goes.

It comes down to the clock speed of a single core in the CPU when dealing with IPT and IAM files. If you could get a really fast single core CPU for IPT and IAM files, it would be all you need.

 

IDW creation with IV2012 does take advantage of multi cores, FEA and Studio also take advantage of multi CPU cores.

Thought I'd have a go at this.

I'm using Inventor 2012 SP1 on windows 7 64 bit on bootcamp.

 

The machine is a 2011 iMac; Intel core i7 quad core 2.8 Ghz with 4Gb ram.

I got a shade under 15 seconds.

Minor nitpick: each core runs at full clock speed.  So IV is using 1 core at 3.1 GHz.  You have 3 cores at 3.1 GHz for all the work you can do while waiting for IV to finish calculating.

Home computer:

  Windows 7 64-bit SP1

  Athlon 64 3200+ 2.00 GHz (single core, five years old)

  6 GB DDR2 RAM @ 800MHz

  Radeon HD 5670, 512 MB DDR5

 

  Inventor 2012 SP1: 44 seconds

  Inventor ?: 40 seconds

 

Work computer, operating locally at home, but with design data, license and other projects located on work server, specs in my signature below:

  Inventor 2012 SP1: 26 seconds

 

Odd difference that I noticed in trying this on two different computers: on my work computer, it took as long or longer to re-solve the sketch after changing the dimension as it did to rebuild the part when I finished the sketch; on my home computer, the re-solve was to all appearances instantaneous.

I am new to overclocking so stopped at 3.56Ghz as that takes the ram to 800 and my ram is 800 so not game to go any faster.  Temps and volts are fine so going to stay at this overclock.  Still at 19 sec's tho.  Tried with the GTX 560 card no change.

 

I dont get rebuild error but I'll bet it's the workplane.  Whenever I create a workplane by selecting a projected 3D curve and its end point it fails randomly.  In one file 3 update fine, two fall over.  I have submitted a sample to my VAR, but no response yet. 

 

I was hoping there would be a machine out there that would get under 5 sec but some of those specs are pretty good.  So it looks like I have found my bottle neck.  Although simpler, I have lots of sweeps that use normal to surface option.  So until we get multi core processing or significanlty faster CPU's it's going ot come down to workflow. (looks like Windows 7 might also take a couple of seconds off)

 

Its been an interesting test, thanks to everyone that participated.

No not over at all, the more results we get the better for helping us all (and hopefully Autodesk if they are watching) get the most out of our systems.  Interesting that your i7 smashes the others, then I notice every one else is using 2012.  Makes me wonder.

 

My overclock is faster but I am still heaps slower, so either there is more to the processors than just speed, or win 7 is that much better than XP.  And the laptop at 2.2Ghz is close to mine at 3Ghz.  Again Win7.

 

I might have to bite the bullet and upgrade to Win7, but the thought of finding my disks and reinstalling everything else doesnt excite me.

I noticed my video card drivers were slightly out of date so I updated them and ran again.... 11.1 seconds Smiley Sad.

 

Then I tried my laptop and got 23.0 seconds... Smiley SadSmiley SadSmiley Sad
