That depends upon what you mean by "64-bit capabilities".

Most integer variables are of type "int", which will probably be 32
bits. E.g. raster maps will be limited to 32-bit row/column indices,
integer cell values will be limited to 32 bits, etc.

The main advantages of a 64-bit architecture would be to allow the use
of files larger than 2Gb and/or the use of more memory than would be
available on a 32-bit system.
