Thanks, that explanation clears the water somewhat.

@cicciocb
The first is the Cpu speed that can be selected to 80 or 160 Mhz in the ide
The second is the Flash speed that can be also selected to 40 or 80 Mhz in the ide.


So what I am setting in this picture is the clock speed the CPU will run at?

Where is the option to set the flash speed? I only see the option for upload speed in (?)bauds.
And how do I ask for real cpu speed in a sketch?
