| Idle yes, but HBM energy consumption / memory operations seems to be a bit better than DRAM. |

| Only if you’re running at 100%. Consumers generally do not. |

| ▲ | vlovich123 an hour ago | parent [-] | | LPDDR/DDR/GDDR generally still win over HBM when there’s no data being transferred. HBM is primarily better in watts/byte transferred. Consumer electronics spend most of their time idle. | | |

| ▲ | vlovich123 19 minutes ago | parent [-] | | Right, but HBM idle is significantly worse than LPDDR idle or even DDR idle for that matter. That matters a lot precisely because the device is idle most of the time. Your idle power draw dominates. |
