There's nothing new or special about that 28W number: that's been one of Intel's standard product segments for years.

- ajross 3y agoYeah, the 28W number is a load consumption. The driver of "battery life" is idle management, which as much or more to do with OS software as hardware design. (Also, it needs to be said, with simple battery capacity. Apple ships a monster 72 wH unit in the current MBP, which is fully half again as much as typical Intel/AMD/Chromebook devices.)
- wtallis 3y ago> Yeah, the 28W number is a load consumption. More specifically, it's the sustained power limit used as a target parameter for the processor's power management control loop. It's not a measurement of any specific workload, and doesn't take into account any part of the system outside the Intel chip; DRAM, display, storage, etc. are not included. And laptop OEMs have some leeway to tweak those power limits, and wide variation in their cooling systems so the achievable power draw within safe temperature limits can be quite different.
