Is 64 bit really that much faster than 32 bit CPUs?
I think the number of cycles per second isn't really any different, just the maximum amount of RAM you can have. But really for now 1 to 2 gigs of RAM should be fine.
Even if you use 64 bit Windows, running say a 64 bit Game, is it really any better or faster?
I don't know squat about hardware but i think one advantage that a 64 bit cpu has is that it can access more system memory. Larger chunks.
There are more instructions available to it, and it can perform opperations on more data at once. I think.
It can execute two 32 bit instructions at the same time. Almost doubling performance. (Except when there can be contention, i.e. the result of one instruction modifies the data on the other, then it must wait)
Also it can read or write two 32 bit instruccions or two data from memory at the same time. :wave:
Yes, but then again, software will only run faster if it takes advantage of the new 64 bit features.
