CPU for 3D modelling (autodesk inventor 2015)

[BelgianNoise]

This is fictive, I am trying to help out a friend ffor school while also learning about hardware(my fettish).

The assignment is to make a build for a 3D modelling pc that runs "autodesk inventor 2015".
Now the site recommends a XEON E3 or Core i7.

But since years have passed i5's are now more viable and most important: Ryzen.

What would be the go to CPU for a budget of 2000eu for the build.(please dont give a full list, trying to learn more about the CPU and maybe Mobo here)

I am trying to get serveral builds, a budget one, a medium one, and a "top of the line one" which would make all of those 2000eu fade away.(ofc for the whole build)

I know my Recent Ryzen and Core i CPUs but i am not familiar with XEON or maybe threathripper, maybe an i9 is a good pick?

So i would like to have recommendations on several CPUs but most importantly: why?

tnx in advance.

A friend of mine needs an upgrade for his Autodesk and 3D rendering PC, I'm outfitting him with the top end Ryzen 7 CPUs once they come out early next year. Also, don't forget about loads of ram!

If the software likes cores, then Xeon. If it's not picky, then go with the best bang for the buck.

nVME drive, and loads and loads of RAM.

about that RAM. 2k isnt a lot. do you think i should try and fit 32gigs in there?(might not be 2k but a littel less)

Do you have a recommendation for the XEONs. I dont even know how their generations are noted

I know for a fact you can get a full ATX tower, 8 cores with SMT, and 64GB of DDR4 3000 at least in that budget, all on a decent X470 motherboard and a good graphics card, like 1070 range if you want new and 1080 if you get used from eBay, which I recommend.

Start here, around number 7 (sandy bridges)

https://en.wikipedia.org/wiki/Xeon#Sandy_Bridge–_and_Ivy_Bridge–based_Xeon

 

They are like std CPUs, but with more of everything (including price, unless you buy used)

Q: Does having more CPU cores improve Inventor performance?

A: Designing and modeling in Inventor is not able to utilize more than a handful of cores. We have found that a CPU with the highest operating frequency will give you the best overall performance for general modeling tasks. Intel's mainstream Core i7 8700K currently offers the highest single-core clock speed, so that is our go-to recommendation. Rendering with the built-in engine, however, can see moderate to large performance gains with a higher core count CPU. For that reason we use Intel's Core X series i7 and i9 processors with eight to eighteen cores for our rendering-optimized Inventor workstation.

 

Seems like higher core count CPUs (like Threadripper) won't do much for modelling as its frequency/IPC dependant, but rendering will see sizeable gains.

 

On a 2000 euro budget, you can probably afford either a Skylake-X or Threadripper based PC. Another choice would be the 9900K, since that combines the fastest single core speeds along with good multi-threaded performance (8 cores).

[scottyseng]

8700K / 9900K from my experience with autodesk. Revit and Inventor tend to be poorly optimized and prefer faster single cores. It changes around if you want to render though.

 

Ryzen is also a solid choice.

these worldloads dont benefit from a Quadro or an RTX card? im not really aware of those lineups.

Not sure, but you should definitely do some googling with the specific software that is to be used to see benchmarks of graphics card types.

I do a ton of cad work and I have a Ryzen 7 1700. Threaripper and the Core i9's are pretty excessive in my opinion. Also with AMD announcing AM4 support through to 2020, we will probably see some pretty powerful CPU's on the current socket meaning it could run on your current motherboard. If the leaked info is any indication then we are going to see some crazy powerful CPU's from AMD next summer.

 

Also, cad loves cores but isn't totally optimized for AMD R7 CPU's yet, an i7 will be faster but with optimization changes, this could change. The i9 9900k is probably the best option but it costs far more and it is likely the end of the current Z370/Z390 platform meaning you cannot upgrade just the CPU.

 

So my recommendation is to get the cheapest R7 CPU available right now and then if you are compelled to upgrade your CPU when AMD launches the new Zen CPU's then you can upgrade. I would recommend a high-end X470 motherboard though. And don't go crazy on a GPU if cad is your primary workload, a 1060 6GB is perfect. You will need lots of RAM, I have 32GB and get nearly full utilization if I am working on multiple designs. Keep that in mind.

why don't you just ask for recommendations on the whole PC? I saw you posted another thread for the GPU, it's unnecessary

I would have to ask in the PC Build subforum where I know for a fact people like posting whatever they like sometimes. and i wont get as much explanations on why they choose the parts.
People will just clutch together a build that fits the budget, i wanna learn something from this.

But i get it tho

if they do so, they will do it again regardless of category

if you don't get any explaination unless you ask for it is bc this is a forum.

 

People aren't expected to know the reasoning of stuff because we assume you guys are busy and such, so you'd  be doing other things rather than learning hardware stuff.

 

But if you want an explaination like I said earlier, just ask "why did you choose that"  or "I was planning on doing this" or maybe "is it true that..." I don't know

 

don't expect the whole world to guess in which way you want the answer

I'm a full tine Inventor user for my job, and I've done my research on this.

 

For general Modeling, assembly and drawing purposes, Inventor cares about one thing and one thing only; Fast Single thread performance. Going from a Xeon 1607 V0 (from 2013 ish) to a 7700k was a huge step up in the speed and responsiveness of the system in general. My recommendation is to get the best single core performance chip you can get.

 

Inventor DOES use multi cores for rendering, stress and fluid simulations, but if you're not doing a lot of those, multiple cores wont help you. If you're wondering why that is, the explination I was given is that the core kernel for the program was optimized for single threaded CPU's back when the program first came out, and it has been the same since Inventor 1.

Nope. GPU's only help display the image on screen, so anything beyond a Quadro P1000 or a 1050 isnt much of an improvement. Yes, Inventor does have raytracing but at this time there's no way to incorporate the Turning cores in RTX for that purpose

I've always thought that CAD modelling was more single thread intensive? Except for the rendering side of things, of course, which generally scales well with additional cores. According to Pugetsystems, Ryzen seems to be quite sluggish in the modelling side of things, which makes sense because AMD is behind in ST performance. I can somewhat understand your rationale of using Ryzen 7 as a placeholder, but we have no guarantees that next gen Ryzen will bridge the ~50% performance gap in ST performance:

it's because you are blaming people for not giving you a plethora of text

It is, but as you said for rendering multiple cores make a difference. For most cad work frequency is still king. But I personally have noticed a performance boost with my R7 1700 vs the i7-6700k I had before just in rendering time, but to be fair nowadays I mostly work in Inventor and the majority of what I do is simulation renderings.

 

As I mentioned the i9-9900k is probably the best CPU you can get, it has 8 cores and can OC to 5.0GHz, but in terms of value, I think the Ryzen 7 CPU's make more sense. 

 

And if even just sliver of information is true about the leak on AMD's next-gen of Ryzen CPU's then I would hate to buy Intel. As the upgrade path for the current platform is likely dead. This is just my opinion though!

[bimmerman]

Focus on fast single threaded performance primarily. I don't know about Inventor but Solidworks can benefit from cheapo Quadros more than higher end consumer cards due to driver support-- see this video for GPU specific recommendations:

 

For CPU, I'd suggest either an R7 2700/2700X or an i7 (8700, 9700, or i9 9900). I likely wouldn't bother with a -K variant of the intel chips unless the eventual owner is wanting to overclock and is knowledgeable about it. R5 2600 or i5 9600 are good choices for cheaper builds.

 

I don't think you need to go with an X299 i9 or Threadripper if modeling is most of what the PC will be used for. I do lots of cad but very very little rendering, so extra cores for that specific use case isn't needed.

 

Realistically though ANY of the high end consumer CPUs (see above) will be fine. Go for 16gb of ram at a minimum; 32 if you can swing it. I'd shift CPU budget towards GPU and RAM, personally.
