RE: cpu architecture



Look at the flags. The lm flag means 64-bit for both the AMD and the
Intel chips. In addition, the model name will tell you the type of
processor as well as the CPU family. 
Here is one for an Opteron and an Itanium. You'll see that in the x86_64
chips you will have the longmode flag (lm) where you won't in an
Itanium. From Software, 'uname -p' will give you the processor.
