64bit vs 32bit

64bit vs 32bit
What's the difference?
Does the 32bit have a higher performance?

Thanks

If your computer have a 64 bits yo have to use that version

Why?
With a 32 bits you send message to the procesor of this size. Yo don't use all the capacity of the procesoor

If yo use the version of 64 bits you can send larger messages an you need less messages to do the same

for exaple imagene that youwant to send "hola hello" if each letter has a size of 8 bits, with the version of 32 bits you need 2 messages. if you use the 64you only need one

No, if you have a 64bit OS you can use either one. If you have a 32bit OS you have to use 32bit Dolphin. 64bit is almost always faster.

only if the application is optimized

Well isn't Dolphin optimized for 64bit?

Optimized for GOOD material top CPU with x86 works fine shitty CPU with x64 sucks

1º you are right

but you can't compare things that no are the same

Wha is faster? A seat 600 or a porsche carrera?
a 64 bits is always better than a 32 bits processor of the same class (low, medium or hig)

With a 64 bits procesor you can use more than 4GB of RAM. with a 32 bits processor you can't.

not false btw "La Pelotilla" creeps but isn't that bad...

actualy 32 bit windows can do PAE disableing but is VERY! unstable

How often does one need an integer bigger than 4 billion? Gotta make sure that clock doesn't overflow so people can't cheat their way to getting Excalibur 2.
The speed increase comes from doubling of registers (x86s biggest weakness). If the program doesn't suffer from register preasure than you can lose performance to 64bit pointers taking up more cache (also Core2 can't do macrop fusion in 64bit) but ICC and GCC can do 64bit with 32bit pointers to get around this if you don't need >4GB.
