The Minimum System Requirements to Run AutoCAD 2013/2020

Your computer should have a Windows-based PC with at least a dual-core processor or equivalent CPU. At least one DVD drive and a hard disk with 5 GB or more
of free space for the AutoCAD program files and about 120 MB of additional space for sample files and the workspace. In addition to these requirements, you should have enough free disk space to allow for a Windows virtual memory page file that is about 1.5 times the amount of installed RAM. 

AutoCAD 2013/2020 runs best on systems with at least 4 GB or more of RAM, although you can get by with 2 GB. Your computer should also have a high-resolution monitor and an up-to-date display card. An SVGA display with a resolution of 1024 x 768 or greater will work fine with AutoCAD, but if you want to take full advantage of the new 3D features, you should have a 128 MB or greater, OpenGL-capable, workstation-class graphics card. If you intend to use a digitizer
tablet, you’ll need one free USB port available. We also assume you’re using a mouse and have the use of a printer or a plotter. Finally, you’ll need an Internet connection to take full advantage of the support offerings from Autodesk.
