This is a good last resort solution. But I would like to avoid

system_profiler is the only API that provides the human readable
textual description you're looking for. The -xml flag will insulate
you against format changes, and is designed for machine parsing.
Well, I took a different road. I don't want to rely on system_profiler
for additional reasons (one of them is the fact that the -xml
SPHardwareDataType does not work on Mac OS X 10.2, another one could be
not to use a tank (slow and too much information) to kill an ant).
For PowerPC, I still use the old code if the OS is too old. For i386, I
use sysctl with the machdep.cpu branch and another one to get the
family and to know whether it's a multi-core or mono-core CPUs.
