Try to think of TDP as "thermal headroom." It's not efficiency or power consumption. It's room for the CPU to speed up when it's necessary. The boost max going from 4.9Ghz to 5.7Ghz (16%), and at the high end, the power necessary to increase clocks ramps up. In another slide, they indicated ~62% lower power at the same performance levels of the Ryzen 5000 CPUs. So more efficient, but also able to clock higher and get work done faster. For a thermally constrained system, you won't achieve the absolute maximum performance if the CPU throttles, but you do very much benefit from a more efficient architecture (+13% IPC) and process node.
