Whether you are an individual user upgrading to AutoCAD 2012 design and documentation software or a CAD manager/IT professional upgrading the entire company, selecting the right system configuration is essential. The wrong decisions can cause years of frustration for the user. To build a system with greater longevity and better performance, use the recommended system requirements over the minimum requirements. In addition, when buying new hardware, consider certified hardware from Autodesk hardware partners. This is the hardware used in the development of the product.
As AutoCAD functionality continues to expand, multicore functions have been incorporated into the product, most notably in background publishing and mental ray rendering. Every available core is used and rendering is cut to a fraction of the time required on a single-core system. When it comes to rendering, the more cores the better.
In AutoCAD, graphics cards are most important if you are working with 3D models, particularly when applying visualization effects such as materials, shadows and lighting. That said, system stability can be greatly increased if you use AutoCAD Certified graphics and drivers. You will also notice better orbiting, panning and zooming performance with at least 256 MB of RAM.
During operation AutoCAD writes multiple files to the hard drive. For example, when AutoCAD performs AUTOSAVES, it writes a temporary file to disk. We have seen performance degradation in the current generation of solid state drives. We recommend standard SATA drives (7,200 or 10,000 RPMs) because of their higher reliability and faster write times.
Operating System and RAM
Operating system and RAM go hand in hand. With Windows 7, Microsoft has made great strides in stability, memory use and general quality. All modern systems should excel on Windows 7 (64-bit), when using at least 4+ GB of RAM instead of the 2 GB that 32-bit operating systems are limited to. When working on larger data sets, you will see better stability as well as reduced load and interaction times. If you are looking for a little extra performance, we also suggest going with as much RAM as possible to enable your system to crunch those big jobs in a flash.
