On Windows, the 32bit Java runs in client mode while the 64bit version runs in server mode. I don't fully understand the difference but an old coworker of mine told me that server mode has better optimized floating point operations, hence why the 64bit version runs faster and more stably.In Linux, it's all server mode, 32 vs 64bit shouldn't actually make a difference.32 Bit and 64 Bit Java makes just an enourmous difference onto the PC version, especialy stability wise.
This is going back about 3 or 4 years now, mind, so things may have changed, including my memory of the actual discussion.
edit: Pretty close, actually
with the exception of 32-bit Windows, the server VM will automatically be selected on server-class machines
