A nice place to discuss rumors, happenings, innovations, and challenges in the technology sphere. We also welcome discussions on the intersections of technology and society. If it’s technological news or discussion of technology, it probably belongs here.

Remember the overriding ethos on Beehaw: Be(e) Nice. Each user you encounter here is a person, and should be treated with kindness (even if they’re wrong, or use a Linux distro you don’t like). Personal attacks will not be tolerated.

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".
