You could use the "query-machines" QMP command - it returns a "cpu-max" 
information for each available machine type.

If you don't mind parsing the QMP output manually, you can also simply run 
QEMU with "-qmp stdio" and then paste these two lines into the console:

{ "execute": "qmp_capabilities" }
{ "execute": "query-machines" }
