RAM can also enter a low power mode:

A 64GB laptop configured with two 32GB DDR4 modules consumes less than 4.6 watts (W) in active mode and less than 1.4W when idle

DDR5 uses about 20% less power, so for 16GB you're looking at less than 0.3W... likey way less, since a Samsung S24 Ultra with 12GB of RAM claims up to 95 hours "while listening to music". That's on a 5000mAh battery, or 18Wh, meaning less than 0.2W for "CPU + 12GB RAM + Bluetooth + storage".
