Hi,

You can guess cpu speed by running some benchmarks, but it's impossible 
to tell exactly.
Qemu translates arm blocks into host cpu instructions dynamically at 
run-time, and executes them. So, the processor doesn't run the same 
instructions, only the instructions whose effect is the same on the 
other architecture.
