64 bits is more about 64 bits instructions (especially for bitboard engines). You need about 1 clock cycle (1*64-bit instruction) instead of 2 clock cycle (2*32-bit CPU instuction).
I hope I was clear ...

Hi,

is that 64b architecture neccassary, what is an advantage? 32bit seems to be enough to host chess program. Programs are not so big to need 64b addrress space.

The reason might be Java which is memory consuming when garbage collector is sleeping Smile but good written C program ....
