In version 1.0.9 the 32-bit code was actually faster than the 64-bit code. But in version 1.0.10 the 64-bit code is faster again.

A quick test run on a primegrid range with a C2D @ 2.67GHz:
Code:
version 1.0.9 64-bit:    61 kp/s
version 1.0.11 32-bit:   83 kp/s
version 1.0.11 64-bit:  100 kp/s
edit: from the Cullen 2M sieve, p=1000e9
