Where do you get this number 35W from? My Ivy Bridge 3470 idles at 7 watt (cpu only). Most of energy is consumed by the monitor anyway (20-25 Watt) anyway, so the energy savings are minuscule.
- FirmwareBurner 3y ago>Where do you get this number 35W from? A google search on benchmarks and tests.
- SomeRndName11 3y agoI actually measured the whole system. With motherboard, HDD, SSD and RAM it idled at 30W. CPU took only 7w from all of that.
- FirmwareBurner 3y agoHow did you measure CPU draw?
- SomeRndName11 3y agoReported by the motherboard's current sensor.
- FirmwareBurner 3y agoIs that accurate?
- Dalewyn 3y agoCPU and mobo sensors are accurate enough for casual measurements and conversations like this. The numbers I cited earlier were reported by the CPU's package power sensors which were in turn read by LibreHardwareMonitor.
- SomeRndName11 3y agoWell if you count expected power consumption of each component and limited efficiency of the power supply, plus reports of people idling their 3470 based machines at 12w (full system) yeah, good enough. I mean what is your point? The 35W idle for Ivy Bridge CPU only is a ridiculous claim, that should be retracted IMO.
- squeaky-clean 3y ago(Not the same commenter) HWInfo64 can report your CPU power consumption. Some digital power supplies can also give power for specific parts, like corsair iCue compatible PSU's
- formerly_proven 3y agoIdle power consumption is hard to compare because peripherals, configuration and firmware have enormous sway. However, painting with broad brushes, Sandy Bridge has modern power management and idles comparably to newer CPUs (a lot better than some modern ones even).
