ELI5: How does one understand how fast a computer will be simply by reading the specifications, like a clock speed of 3.3GHz?

For example does Moore's lore actually make computers twice as fast in the allotted time? Or does it simply increase an arbitrary number that doesn't increase the functional speed of the computer? I guess the overall arching question here is, how can one make sense of these numbers and fully grok computer specifications' implications on practical and functional performance?

Moore's law specifically measures the number of transistors on a silicon chip will double every 18-24 months. Transistors are little switches that turn on and off very quickly, and are one of the main components that are required for a computer.

A clock speed simply measures the rate of which these transistors turn on and off.

So clock rate does not have everything to do with speed, the architecture of the chip is very important. The best way to measure and compare two chips are to actually run software benchmarks on both and compare the performance.
