The 64-bit architecture of AutoCAD 2014 allows the software to utilize more than 4 GB of RAM. This significantly improves performance when handling large datasets, complex 3D models, and extensive rendering tasks compared to legacy 32-bit systems. System Requirements for 64-Bit Systems

Unlike 32-bit systems, which are limited to accessing only about 3.5GB of RAM, the 64-bit version can utilize the full capacity of your machine's installed RAM. This prevents the "out of memory" errors common with complex 3D modeling or massive site plans.
