I wonder if in pursuit of outright performance, AMD stopped optimizing for low power consumption. Desktop Zen3 Vermeer (which the newly announced 5000E series also are) with chiplets idles at around 20 watts, presumably due to having to maintain signal integrity between the chiplets. Similar story with the chiplet-based RDNA3 cards idling at 100W. Anecdotally, my Renoir laptop is also lacking in battery life.
