64 bitboard and more registers are logical reasons but it concerns x86 only.

Bitboards require 64-bit integers on all architectures, so bitboard engines profit from 64-bit regardless the precise architecture.

For non-bitboard engines, it seems likely that the 64-bit version will be faster than the 32-bit version only on x86, due to the increased number of registers.

3GB memory is enough for a chess program.

Well, if you have 32GB in your machine it would be a shame if a chess engine can never use more than 4GB.
