Inventor 2015 System: Requirements

: Inventor is heavily CPU-bound. For the best performance, choose a processor with the fastest clock frequency rather than just more cores.

Inventor’s performance is primarily bound by the clock speed of the processor rather than the number of cores for standard modeling operations. inventor 2015 system requirements

If you are working on "Large Assemblies" (typically defined as more than 1,000 unique parts), the hardware demands increase significantly. Intel Xeon E3 or Core i7, 3.3 GHz or greater. RAM: 24 GB or more. GPU: Dedicated workstation card with at least 2 GB of VRAM. Virtualization Support : Inventor is heavily CPU-bound
