Do I have 32-bit or 64-bit computers?

[punchy71]

How do I know if I have a 32-bit CPU or 64-bit CPU? I have three computers with the following CPU's.

1) AMD Athlon II Dual-Core M300 at 2.00GHz
2) Intel Pentium Dual-Core E2180 at 2.00GHz
3) Celeron 420 at 1.60 GHz

Also which of these CPU's is the fastest/most powerful?

Thank you

All three CPU's are 64-bit.

You have them ranked already from most powerful to least powerful.

Re: @punchy71

all three are 64-bit but the celeron's are not recommended to be used as 64-bit as they are quite LOW in speed SOURCE: http://******/4AaFM :good:
