Hi, I'm new to Arduino. I'm doing some research to buy an appropriate Arduino for my project. I read the specification of Arduino Tre, and apparently there are two different information about the clock rate. One is 16MHz and the other one is 1GHz. I'm confused, what are these two clock rates and which one determine the executing time of an instruction.
For Arduino Due, it has clock rate 80Mhz. So compare to Arduino Tre, which one is faster in term of speed and execution time ?
