New Computer - bad Inventor performance ?

[Anonymous]

Hello everybody,

i just get this new workstation:

Dell Precision Tower 5820

GPU: RTX4000 8Gb

CPU: Xeon W-2225 

and i'm very suprised that Inventor isn't much faster than with my old PC. 

I bench'ed both systems and the new one is just a little bit faster. 

New PC

Old PC

I'm using Inventor 2016. But i'm also tested with Inventor 2021 with same results.

I also tried to update:

- nvidia driver

- chipset driver

- Bios update

The frame per second (fps) teseted with MSI Afterburner are also nearly the same on both Computers. Only with small .ipt  I get more than 20 fps. 

I testes the GPU and CPU with other Benchmarks (Passmark, 3D Mark) and they are running well. They had the same results like other users with this GPU's / CPU's.

Our new Notebook with RTX4000 Max Q and Xeon W-10855M has a much better score (IPI: 11,24) !!

Do somebody know whats the issue?

Hi! Please share the 2021 results. I would like to understand it better.

Many thanks!

Hi! Many thanks for sharing the data. It does show some mixed performance in 2021. I am a bit surprised. Inventor 2021 should be much better than 2016 in every metrics. Let me double-check with you to ensure an apples-to-apples comparison.

1) Check Tools -> App Options -> Hardware. Make sure both are set to Performance and "Software graphics" off.

2) Unload Add-Ins. Or make sure the same add-ins are both loaded.

3) Clean up %temp%.

4) Make sure Appearance and Material Library are both accessed from local drive.

5) Unplug network.

Many thanks!

Hi @Anonymous,

What are you running in the background?

Specs overall look pretty fine

Hello Johnson Shiue,

hello Leo Warren,

at first many thanks for your help !

And sorry for my late reply, we have tried a lot the last days:

1) Check Tools -> App Options -> Hardware. Make sure both are set to Performance and "Software graphics" off. - Done, no better reuslts

2) Unload Add-Ins. Or make sure the same add-ins are both loaded.

tested, no better reuslts

3) Clean up %temp%.

testes, no better reuslts 

4) Make sure Appearance and Material Library are both accessed from local drive.

yes they are form local drive

5) Unplug network.

tested, no better results

Other things we have tested:

- installed inventor on the new computer without any other software

- uninstalled citrix

- updated all driver (GPU, chipset, Bios)

all this point did not helped

But one very simple setting improved the performace a bit:  the energy option was not set on full power.

After that setting the Inventor PC Index (benchmark) jumped to 9,3 (Inventor 2016) and 12,58 (Inventor 2021).

I think this performance is a combintaion of (old) Inventor 2016 and the slow CPU. I tested his CPU (Xeon W-2225) with other benchmark tools and the results are not that good as new i7 or i9 CPU's.

Before we had bought the this new computers we had thought that its more important to have a higher CPU frequency than more CPU cores. This Xeon W-2225 has only 4 cores and i think this is the bottleneck.

The PassMark Rating (PerformanceTest 10.0):

Xeon W-2225: 10484 (our PC's) 

Xeon W-2225: 11586 (average CPU Mark; https://www.cpubenchmark.net/cpu.php?cpu=Intel+Xeon+W-2225+%40+4.10GHz&id=3678)

in comparison with a CPU with same socket 2066:

i9-10980XE: 34108

Many thanks to you guys !

oh, my latest reply has been deleted.  very unfortunately. i posted a lot about all tests and changes 😞

anyway - thank you Johnson Shiue and Leo Warren for your help !

Hi! Oh no. Do you have backup images? The forum has behaved a bit flaky recently. Posting a reply isn't instantaneous. Did you see better performance now?

Many thanks!

Hi,

we have tested almost everything 🙂

- all drivers updated (Chipset, bios, GPU), even tried to downgrade the GPU driver

- disconnected from network

- installed Inventor 2016 on a complete new Computer without any other Add-Ins or other programm

- etc. .....

One very simple thing we had found was the energy option wich was not set to full power. I was very suprised about that because i thought this settings reducing the power only on Notebooks 🙂 

After chaging from eco to power mode we increased the score in Inventor Benchmark:

Inventor 2016: from 8,41 to 9,18

Inventor 2021: from 8,88 to 12,4

In conclsuion, i think the reason of the bad score is a combination of (old) Inventor 2016 a the weak CPU (Xeon W-2225)

best regards
