Hard to say, but I wouldn't expect a benefit because bigger data types means also more cache pollution.

Normally the code is a little bit smaller (less sign extensions), but the data footprint is bigger.

The comments above are probably valid for all 64 bit CPUs except alpha which is not supported by fpc.
