Need CPU for 3d modeling/rendering purposes (3DS max, Archicad etc.)

post #1 of 32
Thread Starter 
Hey. So I am looking for good CPU for 3d modeling / rendering purposes, mainly ArchiCAD and 3DS max, and some other Adobe software (Illustrator, Photoshop etc)
My budget is 300-400€.

Can you guys recommend a few? I was told i7 5820k, 5930k are great, but they're slightly above my budget. I was looking at this i7 4790k but I don't know how it deals with rendering tasks. Some suggestions would be appreciated. Thanks

hey fella for that money you could pick up a second hand workstation, ive just bought a second hand dual x5650 z600 with 16gb installed for less than £200. it may be old but its capable of running SW15 and AC inventor. ive just stuck a gtx 970 in it for folding fun.

Just a thought ?

It's all relative in my opinion. I've been running 3DS Max since version 5 or 6 on different processors and platforms throughout that time. If you can install the program then you can technically render anything on any hardware configuration. You just increase or decrease render times.
For general 3D work and goofing around or student projects in Max any quad core i5 processor, 16GB of gaming memory, and a mid range GPU will have you moving right along.
If you have clients to please in short time frames that can result in big payouts then you'll need a stronger machine to get your work done faster.

I'd recommend spending your money on SSDs in RAID before dropping big for a 5930k. The 4790k should work great for you.

Thanks for your input. I'd prefer new computer with warranty and everything, so it lasts few years before upgrading to new one.

My sister is a student of architecture and she does visualizations for her clients (nothing big, but slowly getting there). Up to now she has been using my gaming PC which has i5 4670k, 8gigs of ram and r9 280x, and I can say that it got the work done fairly well. Since she has the budget of 1100-1300€ (for PC, so I assume 300-400€ for CPU alone) I want to build something a bit more powerful, something that might get the work done in shorter amount of time. Since i7 4790k is almost as old as i5 4670k I was afraid that maybe it's a bit old CPU to buy in 2016?

I'd also like to know on which components can we "cut some budget", so we can spend more on CPU and ram? (I assume the 200€ Motherboard is not needed for something like rendering). Also, does graphic card make much difference? (For example second hand r9 280x for 140€ compared to new GTX970 / R9 390 for 350€). I was also planning to get SSD of 512gb, would you recommend more?

The video card has very little input on rendering. Rendering images from 3DS Max is performed almost entirely in processor and memory calculations. You will get an increase in FPS while working in the 3DS Max viewport with a more high end video card. Especially if you are using a lot of high quality textures/materials. Almost exactly like in a game. Video cards help in the real-time work and much less in the rendering of images and animations.

You can save money at the motherboard for sure. Save money on memory too. 16GB should be enough for most projects with room to upgrade later. A single 512GB SSD will work very well though she/you may need a 1TB or larger drive for storage. Use the 512GB for projects you're working on and then move them to your 1TB when you're finished.

If you can afford a six core processor then get one. You won't be disappointed! However, a nice quad core w/ hyperthreading makes a very capable machine.

Mind you, almost all of the equipment we're discussing here is built for the "gaming" or "enthusiast" market. A comparable Xeon machine is going to cost you many times more. There are so many video cards out there these days it's hard to tell you exactly which one to buy. In general, with 3DS Max you'll benefit from a single card with lots of onboard video memory and high clock speeds....just like in games. However, you can save money here as well since the video card has less input during final production.

Thanks a lot for your answer! I think I'll go with this build: http://i.imgur.com/7qTKXRO.jpg and get 1 512Gb SSD and CPU cooler.
I think this build should get the job done smile.gif

I've done a few builds for Archicad work.
The rendering is done in CPU as the above poster pointed out thumb.gif The best one at the best price is really something like a pulled (from workstation) xeon 2690 - 12 cores for under 500 USD on ebay - core numbers trump core speed every time. Minimum would be 6, 8 is ok and 12 is excellent!
X99 is really the only choice for expanding it later and the Asus cheapest one is fine.

For GPU megabytes is important for moving around the model if it's big - the number of triangles you can fit into GPU before it dumps into normal memory is critical.
I have an R9 390 with 8Gb mem and an R9 nano with 4gb. The nano goes way faster until I get to a big building, then the 390x trumps it. So it really depends on the size of your models.

I have one workstation with an M.2 drive and another with an SSD. Honestly I can't tell the difference in CAD. Hard drives however are pointless, so go with the biggest SSD you can afford and use it with cache enabled.
I use 1/2 terabyte then shift my non current projects to NAS. You need to factor in something like a WD mycloud.
Get 32Gb memory if you run multiple instances otherwise 16 is enough as the above poster pointed out thumb.gif again.

Get the best cooler you can afford. Custom watercooling is best but it's like a beautiful woman - high maintenance. A Noctua D15 is the next best choice. Don't use a crap cooler whatever you do. Use a case that can fit eatx and have good fans - Noctua pumps the air and are quiet. They just look bad. I've gone back to them after trying just about every other one.

I hope this helps you and maybe other CAD people smile.gif
cheers from down under.

X99 is the platform you'll want to stick with for anything CAD or rendering related.

You can snag a Xeon E5-2620 v3 off newegg for $430 USD. It's a 6 core 12 thread. Should be plenty powerful. Stay away from the Z chipset series for heavy computing.

The 5820k is also a fine choice. The toss up between that and the 5930k shouldn't matter too much.

I haven't had or tried the 6 core chips, but the cheaper one should be fine. It has 28 lanes? CAD can only use 1 GPU card anyway, so 1 GPU and 1 M.2 fits into the cheapy no problems.

If the cheaper hex core is the 5820k, then yeah, lanes don't matter for rendering. However, if you we are suggesting a cheaper choice like the E5-2603 v3, then that would not be optimal. It has a sweet price point at $220, but it is not hyperthreaded. A pair of them would be neat to see in a dual CPU board since they're so cheap!

All things considered, the 5820k is a sweet little processor!
