AMD64 slower than i686?

Hm... I Installed 12.04 B1 before it promptly crashed and corrupted my drive, but before that, it seemed much slower than a 32-bit version of 11.10 which I installed before. I bought a new drive, and installed 11.10 AMD64 on it, and again it seemed much slower that i686. Why?

Oh and it's a persistent flash drive I installed the Ubuntu OSs on.

Isn't it the computer's CPU that does all the processing? Is it the fact that the load of 64 bits is too much and 32 bits are lighter to transfer to the computer's CPU?
I have a Intel Celeron something 64-bit CPU.

AMD64 installs will always use more RAM than i386, so if you are low on ram, then i386 will work faster. Drive failure also causes an OS to run very slowly, and even crash. If your drive was a little thumb drive, it was probably near burned out by the time you installed the 64-bit version on it. (Those things can't be written to very many times) Even the flash drives you put in your computer and use as a hard drive have a limited number of writes. Those things don't last very long, especially when there is an OS on it. When the OS can't read from the media, apps can't load and such, ergo your computer is "slow".
