Computer Specs enough

NorfolkSpecialties — Wed, 26 Aug 2020 21:13:07 GMT

I am not computer person at least when it comes to components. we have a tech company that handles all that for us.

Question is i just had them do some work to the computer because it seamed slow a laggy when using inventor. Things that i feel like should be instant take a sec or two to complete. It feels like i am always waiting for stuff after each click i know its only for a sec or less but that all adds up and seams to take for ever. granted some things need to compute but big stuff takes even longer seams anyways.

they said they got it working pretty dang good(cleaned it up and added a larger hard drive) but i dont see a difference so was thinking maybe my computer spec may not be enough. If they are maybe there is something underlying yet slowing things down yet.

Whats everyone running for their super computer for inventor.

Current Setup

Inventor 2021

Windows 10

PROCESSOR: Intel(R) Core(TM) i7-4790 CPU @ 3.60Hz 3.60GHz

RAM: 16.0 GB

TYPE: 64 bit

GRAPHICS CARD: NVIDIA Quadro K620 2048 MB BIOS

First of all, not sure which version of Inventor you are talking about. Attached are the system requirements for 2021.

Second, when you say your IT service cleaned off your computer, I assume that means they ran a disk defrag and system clean up? A company I used to work for had an IT department and one guy in specific used to every 6-8 months ghost the machine, then wipe it clean and reload it. Claiming it was like changing the oil and filter in a car. I suspect you just added new oil or just changed the oil leaving the dirty filter intact. 🤔

My 2 cents.

Windows 10 x64 -16GB Ram
Intel i7-6700 @ 3.41ghz
nVidia GTS 250 - 1 GB
Inventor Pro 2021

For small to medium sized assemblies, your specs look fine. Until last week I was running with no problems or noticeable lagging on an eight year-old i3 3.30 GHz with 8 GB RAM and a wimpy consumer grade Radeon graphics card. That said, I was also not creating massive assemblies of complex shapes, so not pushing it very hard.

The difficulty in diagnosing this is that there are so many other things going on in your computer. Is your antivirus software interacting badly with Inventor? Is your mouse driver up to date? Is there an Inventor add-on that keeps getting in the way? Not being an expert in such things, I would probably start by firing up Windows Task Manager and see if I can spot something besides Inventor using up a lot of CPU resources. In my experience, anyway, it's the CPU that results in lagging behavior in Inventor. BTW, how many cores does your CPU have?

4 cores I believe. But like i said not to sure of the behind the scenes of an computer.

I know its hard to really know whats going on on an computer when your not right in front of it.

I attached a couple snips

From your snapshot it looks as if there's a lot going on with the CPU, without Inventor even showing up in the top thirteen. Don't know if you have any control of what all is running there or not, but that's where I would start.

In the app store is a free app called "Benchmark Tool" that you can download and run, it will rate Inventors performance on your machine. Search for the forum post "how fast is your PC really" to compare your PC against others.

If your security software is constantly using that much CPU - then something in the security software is clashing and that could (potentially) destroy your computers performance.

If your computer has a hard-drive (not a solid state drive), then your system will feel slow and less-responsive in general compared to systems with solid state drives.

Bleeding edge high end CPU's have single thread performance about 40% faster than yours. (single thread performance is the metric that most affects Inventor performance). So, for typical modelling, I think your CPU is fine.

For small to medium projects, your ram is fine. If you are doing larger projects and have unused RAM slots, upgrading to 32 GB wouldn't hurt.

If you are doing very large or complex models, then upgrading to a newer workstation might be worth the investment. TFI has published some excellent information about computer specs.

@NorfolkSpecialties Specs are alright however there is 6-7 Generation gap between your system and the newest stuff available meaning a new system could run as 30-40% better since each generation is around 5% better than the last.

16GB of RAM is fine unless you want to run on big stuff,

a large flag for me is the Quadro which has only 2GB of VRAM - Check in Task Manager if this is filling up as that could be a source of issues.

I can't remember who posted this but a while back someone posted that they change their work system every other year since if an engineer is wasting 5+mins a day every day, at the cost of an engineer for 2 years it costs more than just replacing the system every few years.

Aside from the other suggestions, I'll add one not mentioned. One of the things that provides good performance is good, clean data management and working with rather than against the program. If things are needlessly complicated and/or you're doing things in a way the program wasn't designed to operate, it doesn't matter what hardware is used - it will always be lagging.

Here Is my Bench mark test. I will have to talk with our tech guy and see why that one program is running so much.

it dose have a 500G solid state hard drive

Seeing the score, I stick by what I said - your computer is still fine for smaller models, but if you are dealing with moderate or big models, an upgrade would save you alot of time. My computer (4 years old, i7-6700k) scores about 10. Modern systems typically score between 12 and 16. (Honestly, I dont know how to use the rating, but if when comparing your computer to others you can compare the category totals, which are measured in time. That will give an idea of how much time you could save)
