$10 more a year based on what price of power?
Lots of countries do not have cheap energy after all this climate change BS doing the rounds (again, only this time they primed people in Primary School to believe it as Gospel).
Every 24 hours it runs at peak load vs a similar spec'd Intel system it uses an extra kilowatt hour of energy.
Over three years this could add up to around $274 dollars, in some countries it may be a $526 difference over just three years.
If they're overclocked, as they're closer to the edge they need far more power for a smaller relative gain in transistor switching speed, so you're looking at an even larger difference. Maybe even ~61 watts more than usual.
Which is about $1,275 dollars more relative to a TurboBoosting Core i5/i7 in some countries over that same three year period!
- $1,275 dollars over 3 years is the difference between another whole PC and/or upgrades, or not...
