Which one is better DELL 7770 / 7780

[Yogesh.T]

For CREO 11, to run like a butter, which one is the choice? Can you please suggest. Thanks.

I do lot of rendering and work on huge assemblies. Military Aircrafts.

My work is not stuck with what I have but I want to only go ahead if there is a quantum difference. I do not want to regret the buy! See Image for existing and thinking to buy specifications.

THANK IN ADVANCE!

CPU's are similar with the new one having a slightly higher turbp clock speed.  Extra cores don't do much for program performance.

Any real gain would come from the GPU, for rendering the models, and I don't see your current GPU in the image.

[kdirth]

What is your current GPU?

If it's in the budget, you may want to upgrade the GPU and add more RAM for the size of your assemblies.

Other than what @kdirth mentioned, It looks like your current computer has 64gb of ram and you proposed new has 32.

You may be okay with that, based on your assemblies but you may not!

When you get your new one, do a benchmark (www.creosite.com) on your new one and old one, just to give you a good idea of performance improvement.

It doesn't translate directly to your day to day work "speed" but does give you a good feeling about the performance improvements. It also will help to determine if you need to tweak something. You can also look there at the results and see if anyone has uploaded their benchmark on a computer with similar specs as yours.

Looks like these findings from you guys do not give me an acceptable justification to go with the new, spending almost 4K.

[StephenW]

Are you saying you have a 7770 and want to upgrade to a 7780?  

In any case, it is really difficult to just look at the specs and guarantee better performance. 

My last desktop upgrade, if I compared specs, wasn't much of an upgrade but when I did a benchmark on both computers, it showed significant improvements. I really don't know why other than maybe improved system architecture in the 3 year time span (we replace hardware every 3 or 4 years, per corporate policy)

When you are working in Creo, what is your biggest areas that you notice significant performance issues?

For me, drawings for my large assemblies are horrible, even when I have clean simplified reps and substituting certain large components with simplified versions.  I haven't found anything that significantly improves drawing performance in Creo, it's just bad (my opinion). I don't use other 3d cad software for large assemblies, so I don't have a good comparison I can make.

I have seen other posts where it is recommended to have one built specifically for your needs. Your VAR may be able to provide insight into either a local (to you) company that could build one or they themselves may provide that service.

If your goal is performance, a desktop will get you significantly more performance at significantly less cost than a laptop.

I built my own, saved a bundle of money & enjoy better performance than the big names.

Definitely look at the benchmark results on www.creosite.com for an idea of the CPU & GPU specifications that are the top performers.

[Yogesh.T]

I did some extreme rendering on big assembly and got some data to browse and see what you all think. Pl see images. Random snap of Task Manager performance. What comes up would be interesting to know. 

[TrainStopper]

So it looks like the rendering is being done by the CPU and not the GPU.

A desktop CPU is going to be able to significantly out-perform a laptop CPU for less money.

You captured a "Overall utilization", also set the view to "Logical processors" to see whether rendering is using single or multi-core.

Compare CPU performance for single or multi-core depending on above view and spend your money improving that type of performance.

Also, you are using more than 32 GB memory, so make sure you configure with at least 64 GB.

[Yogesh.T · Accepted solution]

So the solution is to have min 64GB RAM / Intel core 7 CPU and above / 1TB / NVDIA GUI RTX 3500

Don't forget to do a OCUS benchmark (www.creosite.com) on your old system and then on your new system when you get it. 

It will give you a good comparison of the baseline performance difference. It's not 1:1 on actual productivity improvement but it'll probably make you feel like you did good!

[Yogesh.T]

Sure! Where to find Steps to do that?

All the instructions are in the readme file (attached to this post or in the download). It looks complicated when you start reading, but there are some "alternative" instructions shown and more information on how to get a good test. It's mostly about setting it up so it's "out of the box" install with no configs other than the one provided with the test.

If you are changing your current computer to run and and want to convert it back to normal, make sure you write down exactly what you moved/deleted/renamed/changed so you can get it back to working right.

I think it took me about an hour to set it up the first time and then after that, understanding what was needed, it only took maybe 30 minutes total
