How to configure your workstation for Revit
The CAD program Revit has been specially developed for Building Information Modelling (BIM) and enables architects, building technicians and civil engineers to access a common database for each project.
More processor cores = more power?
For single-thread tasks, such as building data modeling (BIM) or for animating entire building complexes, a single CPU core with a high clock frequency is an advantage. Multi-thread tasks, such as scene rendering, are only accelerated by using multiple processor cores. "The more processor cores my workstation has, the more computing power I have at my disposal. This simple formula only works if the following conditions are met:
1 The CAD software used is able to use all available cores (multithreading).
2. the processor cores must each have the same level of performance
Despite the different requirements of the CAD software to the hardware, our workstations are configurable in such a way that all tasks can be completed optimally. Whether you need one or two processors with a high clock frequency, a processor with many cores or a workstation with a powerful graphics card, Uli Ludwig Computer has the right configuration for every application. Due to the close cooperation with our customers in the field of architecture and engineering as well as the software developers of the individual CAD programs, we are able to offer practical hardware solutions for various CAD programs. In order to be able to use the CAD program Revit as efficiently as possible, a single, strong CPU core is required. Revit downloads the required working files into the working memory. For this reason, a workstation with sufficient working memory is eminently important for this program.
The magic formula for the working memory
Revit uses about 20 times the RAM size of the project file when loading a model. Formula: (file size) x 20 = size of RAM required to load the file.
Example: The file size is 800 MB x 20 = 16.000 MB - your workstation needs 16 GB RAM to load a file with 800 MB. We recommend to use 4-8 GB RAM per CPU core. For example, if you opt for a single six-core processor, 32 GB of RAM is sufficient for basic tasks or 64 GB for more demanding tasks.
Revit CPU instead of GPU
The graphics card is hardly used at Revit. Most tasks are processed by the CPU. Therefore it is advisable from our point of view to focus on a powerful CPU. For most applications an nVidia Quadro P2000 is more than sufficient. We recommend using a certified nVidia Quadro series graphics card or an AMD Radeon Pro XW series graphics card with DirectX 11 support.
The selection of the hard disk affects the performance of Revit. The loading times of models and the saving of local models are decisive. You can increase the performance of these processes by using an SSD with fast access times. If point clouds are used in a project, a Solid State Drive (SSD) offers significant performance improvements in the display.
