    Z840 - Not cutting the Mustard.

    I really need some help here, I bit the bullet and purchased a Z840 "HP Z840 Xeon E5-2650v3 2.3GHz 2133MHz 10 Core 2nd CPU 32GB Ram NVIDIA Quadro K4200 Graphics Card" for $9500.00 NZ. The thing is I had all these expectations that my work flow was going to run smoother, renders faster and an overall increase in the speed my computer handles revit 2016. I had a HPE-180a Intel(R) Core(TM) i5 CPU 750 @ 2.67 Ghz 2.67 Ghz & 8GB Ram NVIDIA GeForce GT 230, this computer is over 5 years old and runs exactly the same as the Z840. Can any one recommend what I need to do to the 840 to get results? I don't know much about computers so ill do my best to answer any questions. Thank you.

    Crikey - who sold you that beast?

    Note that Revit only really uses one core (other than rendering and other things like wall join intersection calculations) and hardly uses the power of a graphics card like that but saying that, it surely (from my semi-technical IT ) should be very capable.
    Have you tried running the RFO benchmark test?

    That will let you know how well its doing and give the techies on this forum some pointers...

      Hi purgeme2, as Alex suggests, that's not really a great balance of performance for Revit's needs. Is there any way you can return it? There's not much practical to be done to fix performance. It's like you bought a pickup truck when you really needed a sports car. Sorry for that bad news.

      Where you're most lacking is with the CPU's single core speed, which in most ways is the most significant component for Revit performance. The E5-2650v3 is a terrible fit for Revit. That computer and CPU combination is designed to have two CPUs installed - did you get it with two CPUs or just one CPU? (not that it really matters other than it would be even more of a waste of money to have two).

      Did you get an SSD?

      The K4200 is probably more than you need, but certainly fast enough. Same with the 32GB of RAM.

      All of that being said, while performance is going to be far from what it could have been if you'd gotten a more appropriate CPU, it should be noticeably faster than your old computer. What kind of projects and file sizes are you working with? Approximately how many Revit users in your firm? Revit worksharing? Do you use a file server or just store everything on your computer? Where are the noticeable slowdowns in your workflow? If something is slow, try to quantify it - for example, if you move a window, does it immediately move or is there a delay of a few seconds or more? You might have model performance issues as much as slow hardware. Or maybe your expectations exceed what hardware is available. Even the fastest hardware available isn't fast enough to keep up with Revit.

        If going with Xeon and if running for Revit only. ( I assume this because your Quadro card will be fully utalized in Max rendering and no matter of CPU will ever touch the number of CUDA cores on modern video cards) I would get a the E5-1630v3 it has a much faster clock speed which will be better for Revits majority single core utilization.

          Hi Alex, Thanks for your reply, I brought it over the internet, it has raving reviews all over the internet, that's why I was expecting big things I just had a crack at the RFOBenchmark but is said no Revit found on this machine, maybe because I am running 2016?

            Hi, that's not really what I want to hear , I brought it specifically for revit and the reviews on the internet make it look like a rolls Royce lol. how do I know if I have a SSD? I deal with simple project ie Residential dwelling up to 3 storeys, 70 -100kb, no other employees so just the one user and work of the computer hard drive. I was expecting faster render speeds, and 3d perspective printing. I have just started to use 3d max though the new set up would allow for smooth sailing. What is required to get render speeds up? Will the E5-1630v3 give noticeable results? or am I expecting to much?

              Your 2650v3 along with your Quadro 4200 will give you better render speeds than a 1630v3 in 3ds Max. The 1630v3 will give you better Revit performance. I would be a lot more worried that your Revit files are between 70-100MB and you are experiencing performance issues. Do you have a lot of .dwg imports?

              Please describe in better detail just exactly how you are disappointed in the performance of Revit. What software are you more familiar with that you are comparing to Revit? Are you running the recommended Quadro video Driver?

                Hi Alex, as far as general modelling and draughting goes there is no slow down in performance, I have been using Revit for the last 5-6 years and have only used Revit (AutoCAD before that), I have the latest Driver installed and generally don't import .dwgs. Maybe I am just expecting to much It is the render and plotting speeds that lag, I am wondering if there was any need to update computer now. When the new RFOBenchmark for 2016 is released I will run that and go from there. Thanks for the questions

                  I have attached an edited version of Gordons 2015 "_RFOBenchmark.vbs" script. This should now run Revit 2016. If it don't work for you in 2016 oh well and wait for his new benchmark that hes working on right now. Note this is not going to give you the best compare to the 2015 benchmarks and in no way is suppose to be used to post results on this forum.

                  Make a backup of your current "_RFOBenchmark.vbs" file. Extract the attached zip to the same place as the original. Don't post your results, this is for your own private use.

                    Hi Alex, Probably no point in running the Benchmark if I am not to post the results as I would not know what I am looking at
