AutoCAD workstations are designed for optimal performance to give you the power you need to efficiently complete your work. Recommended for performance: Processors Speed Faster the better. Recommend 3Ghz or higher. Processor Cores Higher core counts are only utilized when rendering. We recommend 4 cores or more. Memory (RAM) 20x of your compacted central project file is a good rule of thumb. Recommend 16GB or higher. Storage Faster drives will improve overall workstation responsiveness. Its recommended to use a SSD for the Operating system and program loading, and HDD for file storage. Graphic Card (GPU) - Dedicated video cards supporting DirectX 11 or later are strongly recommended. Nvidia Quadro are supported and certified by AutoDesk.
