In lecure, Professor Kayvon asked which direction does increasing clock frequency go towards. Increasing clock frequency moves up and to the right, because more energy is used per operation (to increase the frequncy), and more operations are done per unit chip area.

@koala. Not "more operations per unit chip area" put operations per second per unit chip area. Operations per clock per area is the same as frequency increases (since the chip isn't changing), but operations per second is since frequency is going up.

Pareto Curve shows what the best configuration (x-axis) is for a selected energy efficiency (y-axis).

Essentially, the point closest to the bottom right corner of the graph will have optimized the trade-off between performance density and energy consumption (being the most energy efficient for the performance achieved), although it may not have maximized the performance density. Determining which of these is better will depend on the applications.

I think the entire ARM line of processors effectively spans this line. They have very low end, low power processors suitable for small embedded devices (e.g. washing machine), as well as a series of much higher end processors for things like a raspberry pi, and everything in between (e.g. car entertainment system). Intel does the same, but they tend to focus a lot more on the higher end desktop grade of processors.
