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

| That hasn't been true since early HBM2 days, before the controllers standardized on power/voltage management and did things like leave them in P0 to ship on time |

| ▲ | vlovich123 18 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. |
