/proc/cpuinfo cpu database?

[Kenneth Burgener]

Is there a list, or a database (similar to pcidatabase.com), that lists
the processors based upon the "cpu family", "model", and "stepping"
found in /proc/cpuinfo?

For example:
cpu family 15
model 6
stepping 5

The wiki[1,2] has a good list of processors from AMD/Intel but the
listings are all based on a "market name" and "stepping", but their
stepping is a "letter - number" where /proc/cpuinfo only shows a "number".

The main thing I am trying to determine is if the CPU is a 64bit
processor, and the only true way would be to look up the processor,
correct?  (uname only indicates what kernel is installed, not what is
possible)

Thoughts?

Thanks,
Kenneth
