This is just obviously untrue. You can run these chips with more power, but they automatically scale, so if you limit them, they'll still outclass current low TDP options. You might pay more for the privilege and leave potential performance on the table, but these are actively more efficient than past options, not less, you just can drive them for more performance rather than more efficiency if you want. Of course, having higher performance can actually be more efficient in some workloads, as there are cases where running for a short time at higher power draw and then reverting to a very low power idle state is better than running for longer periods of time at more limited power draw to do the same work. They explicitly list a 25% performance-per-watt gain. They push more power to get even more performance, but you can choose if you want to do that. They claim at 65w TDP Zen 4 is 74% more performant than Zen 3.
