mid-budget machine for cad.

Postby bdub » Sun May 08, 2016 6:00 am

long time amd builder here, but I work with xeon machines at my job. while I'd like to recommend an amd base for someone who wants to run CAD program...

http://www.graphisoft.com/support/syste ... 1462465800

...i understand that amd might not have what is needed for this.

so I'm putting together a parts list based on latest intel skylake (lga 1151). this processor is what I'm thinking about...

...but i am amendable to other cpu's (or socket types) if there's a better recommendation out there.
also need 32 gigs of ram to go with a motherboard to fit this cpu. mobo doesn't need a lot of bells and whistles. plan on a regular sata (not crazy for m.2 yet) ssd for the OS and TB hdd for data, along with a burner of some sort.

i notice there's only dual and quad core cpu's available in skylake. I'm guessing the lower priced quads don't hyperthread? would it be better for cad to have hyperthreading, or not?

here's the psu I'm eying for this project...

tryna keep the cpu price down so i can put a low budget quadro (or possible fire) card in it, as i hear most cad software uses the gpu's compute capability pretty extensively now, and I'm guess they work better with professional card more intricately. thinking about the k600, which runs around $160. would like the new m2000, but i think it is out of the price range for this build...
possible a consumer card would be better based on budget?

which gets to budget.... trying to keep the cost of the psu (which i think a 600W would do), cpu, mobo (partial to gigabyte or anything BUT asus), ram, and gpu to about 700 bucks. the other stuff (disks, case, fans, kb/m, etc) is ancillary at this point.

thoughts and suggestions?
TIA

edit : here's a short selection of gpu's that could be possible...http://www.newegg.com/Product/Productco ... 4%24%24%24

partial to the w4100 at that price, but unfortunately out of stock. the 300 dollar card is prolly too $$$.

As what you are doing is specific to get the best performance/$ you have to unravel how good the ArchiCAD implementation is for the different architecture/acceleration (and on their roadmap) and where the bottlenecks are for both the App and for the type of models you are running.

I've done plenty of CAD but I am unfortunately completely unfamiliar with ArchiCAD so I'm of no particular use here other than to say it really is application specific.

A big sell for a lot of the workstation cards is their ability to dramatically increase rendering etc speed with GPU acceleration BUT a surprisingly large proportion of apps implement absolutely no GPU acceleration whatsoever! Others CUDA only, some OpenCL acceleration, very few have both and even those tend to be buggy for one or both.

Some have crappy support and crippled features for ATI and/or Nvidia non workstation-GPU drivers, others less so, some only have proper support for either Quadro or FirePRO, quite a few implement both but FirePRO support tends to be more buggy.

And then you can consider the same scenarios all over again for AMD vs Intel microcode and multithreading support etc.

And then you look at all the bottlenecks, BIm usually means huge models which means superfast SSD is FTW. Maybe you get a big bump from having a large processor cache, RAM needs and constraints should be pretty easy to assess based on looking at resource use of your current setup.

Spec is made tricky as most software providers are very opaque about these features making it difficult to work out the facts. I've also come across a LOT of IT support making really silly wasteful purchaces , such as a high spec Quadro cards for users who only do flat 2D alignments on graphics card makes absolutely no difference whatsoever, whereas spending a quarter of the money replacing the users antiquated 15" monitor for a reasonable 23" height adjustable screen would have made a real productivity difference. Haha, sorry I am ranting now but hope some of the earlier stuff is of a little use.
I have now left the Building :tongue8:

thanks for the reply. here's what I recommended...

http://www.newegg.com/Product/Product.a ... 6814133560

the gigabyte mobo is h170 variant. 6500 skylake, corsair 2x16GB 2133 "lpx" ram, seasonic 620w psu, and a quadro k620 gpu. comes to under $650, less if count rebates.

this is in direct competition with this...

which is what the customer was originally going to buy.
