The AMD-based system is cheaper, but you 'pay' in higher idle power usage.

That 6W more costs around $5.26 per year at $0.10/kWh, which is basically nothing.

In SF Bay Area, the cost of electricity is $0.42/kWh, so around $20/year for just extra idle usage. Still not a lot, but it adds up.

Yes I pay $4/watt/year in bay area.
