The largest benefit is being able to convert huge books, such as the Delphi classics, if you use 64-bit Calibre and have 8GB RAM or more. The same is true if you convert 3-4 large books at the same time. I often see Calibre easily hit 6-7 GB RAM usage.

Under Calibre 32-bit, the program can't use more than 2GB in total. I don't know what happens if there isn't enough memory to complete a conversion. It might be aborted; Calibre could also possibly crash.
