![]() it has this thing called Adapative Degredation. Go look at AutoCAD's graphical setup (new versions you have to use the command -GRAPHICSCONFIG to get a detailed setup). Here's the link to the test system and drivers that you weren't able to find reference to: It may not have application settings (for AutoCAD or Inventor), but generally they tend to leave all the options set to the default.įPS is the only valid benchmark for CAD. Overall, I don't trust or rely on PassMark. I haven't checked out the PassMark tests fully, but just looking at it, it doesn't give any breakdown of what tests were performed, under which API, or with which system. Yes, 3Dmark is mainly for desktop cards because it tests soley DirectX capabilities, to which I've stated that workstation cards fair better (generally) in tests dealing OpenGL, rather than DirectX. ![]() It might just be that the workstation card won't perform as well as a desktop card with that program, too. ![]() If I were you, I would search to see if anyone has benchmarked the other program (that uses OpenGL) that you use and compared workstation cards vs. There are applications out there that will make better use of a workstation card, but Inventor isn't one of them. Workstation cards do perform better with the OpenGL API. So the Double Precision performance and error correction capabilities that the workstation cards have over the desktop cards is, I believe, a moot point. only for displaying 3D objects on the screen. I like the video that Neil brought up however, I don't beleive that Inventor uses the GPU for any calculations. The GTX 770 also performs better than the Quadro 4000. See this link for performance comparisons for several models: As you can see, the R9 290X performs the best in Inventor 2013 out of all the single GPU cards (the 7990 and 690 are both dual GPU cards). They also have higher performance than nVidia's cards of the same price/model range. ![]() I personally like AMD's desktop cards for use with Inventor as they tend to give higher performance than their workstation cards. Since Inventor uses the DirectX API, pretty much any graphics card will work with Inventor. The real difference between the workstation card and desktop card is the firmware and the associated drivers/software. NVidia Quadro's (workstation cards) and GTX's (desktop cards) are basically the same just like AMD's Firepro and Radeon models. Īnd the last thing - if Quadro k4000 will perform equally to GTX (770 or 780, idk) in Invetor i will definitely choose Quadro because of OpenGL software installed, but if GTX will outpreform Quadro - i definitely choose the leader, because i can withstand with lags and slowdowns in OpenGL software but i cannot afford them in Inventor Like hyperthreading - actually you have 4 cores but the tast spreads into 8 threads. So i wondering GTX or Quadro k4000, however, GTX specs are more impressive but some forums say that quadro have "real" CUDAs and GTX - not. I also do not know what is CUDA processors and do they do any use in Inventor or Ansys (primarily, steady state thermal and CFD for PCB Designing) The thing is i'm working with some OpenGL software but no so often as with Inventor so my first may say requirement is to make the running of Inventor as smooth as i can afford. I am making a new build of the stationary PC because was working primarily on laptops - one with GTX 860m and the other with QUADRO 4000M and want to increase performance because large assemblies are running not so smooth. And i doubt if it worth its money in comparison with GTX 770. I have a very good deal on Nvidia Quadro k4000 for $300 and 1-year used.
