How are there multiple "Energy per Operation" points for almost the same "Performance Density"? Or maybe I'm not understanding the chart correctly?

@kevinle1, this chart is the combined measurements of ~50 different designs, where some of the data points may be older designs. Sometimes adding a feature to a design might have significant energy cost but only provide negligible performance gains. So you are reading the chart correctly.
