    Revit 2016 - Rendering Benchmarks compare, please help.

    Hello, I would like to buy a new PC for AutoDesk rendering but I would like to know if the current one is good or bad.

    Can someone provide me with a Revit file and tell me how much time it takes for them to render the file, their computer configuration and provide me the same file so that I can compare how long it takes for me.

    Currently I have
    Intel 4th Gen i7, 2.00 GHz upto 3.1 GHz
    8 GB RAM
    5400 RPM 1 TB Hard Disk
    Nvidia 840M 2 GB Graphics
    Windows 8.1 Single Language

    I need to know if it is good enough.


    Please help.

    Revit 2016 just came out, so you are not likely to find much in the way of benchmarks yet. Our own RFO Benchmark has a rendering section, and there are lots of results for comparison, but only for 2015 and earlier. I am working on the 2016 version as I get/make time, and I do hope to have it finished soon.
    That said, if you do a LOT of rendering, Revit is just going to be slow, period. It is a CPU render, the GPU does no rendering work. Even in 2016. And "good enough" is such a relative term. Your current machine may be just fine if you occasionally render small projects (single family houses, lets say) and don't have short deadlines. If you need to render very high quality images of multiple views of a very large project in an hour then there is no computer on the planet that is going to get the job done in Revit.

    This is the response I was looking for. Thank you soo much. I will buy a new PC but I won't buy a super high end one and waste my money.

    However, I would like to know if I should go for local CFD analysis or use AutoDesk's cloud. Will I be able to run a local CFD analysis on my current configuration?

    To add on here if rendering speed is the most important factor then perhaps cloud rendering is a better choice? The speed of cloud rendering can't really be matched by any desktop PC rendering in Revit locally. This of course may not be for everyone.

    But to answer the question more directly; I rendering the "from yard" view from the rac_basic_sample_project on my ~4yr old dual Xeon processor machine Here are the results.

    Setting and rendering time displayed 7 some odd minutes

    Just for comparison I did the same file rendered in the cloud.

    Much higher resolution file settings need to be adjusted a bit for the cloud rendering. Time from clicking "Start Rendering" to getting an e-mail it was done; 2min 23sec.

    Thank you.
    The file I am trying to render is a 22 storied building and the file size is 350 MB.
    It takes quite a while. At best quality it was at 12% after 8 hours. After that I aborted the rendering.

    How much does it cost for cloud rendering? Can only a limited number of files be rendered depending upon the size and quality?
    Where would I get more information about this?

    Cloud credits cost $1 per credit (minimum purchase is 100 credits) the amount of cloud credits used for a rendering depends on the quality setting and the final image size. You can render as many images as you like only limited by the size of your wallet .

    Thank you, I am planning to go for it.
    So if $1 is 100 credits, how many credits would my 22 storied building with 350 MB file size take?

    Or if that is not answerable, how much would one of those sample files provided take?

    Prior to rendering, is the whole Revit file uploaded to their cloud or something else?

    File size of the Revit file does not matter. It is the image size and render quality that affects the cost of the cloud render. Largest image (16MgPxl) and highest Quality (Final) is 16 cloud credits. Prior to rendering the entire Revit file is uploaded to the cloud.

    We have been using Autodesk's cloud rendering for about 2-3 years now. It is convenient for doing quick, iterative designs. Preview renderings (low resolution) are about 1 credit. 8 credits will be good enough for a Powerpoint presentation, and high resolution images can be 16 credits. Our average rendering user consumes about 300-500 credits per year, and our intensive designers may consume 2,000-3,000.

    Autodesk introduced the cloud rendering with 3ds Max 2016. One of our designers has been trying this out. So far, no reported issues.
