As far as AC goes, I live in the Bay Area, and I didn't even have an AC until this year, and so far have only used it twice. Otherwise I'm at a loss to explain Tom's numbers, unless I'm reading something totally wrong.ģ. The only explanation I can think of is that the rig configuration was totally different, so other parts of the computer are contributing to power draw and not just the GPU alone.

The power delta between a 970 and 290 is about 100W at most, so in Tom's charts the card closest to that criteria is the HD 5850 at a power delta of 103.7W, which somehow translates to a difference of 316.09 kWh and a cost of $41.09 per year.īut going from a power delta of 103.7W to 316.09 kWh per year (so 0.866 kWh per day) actually requires you to be gaming a full 8 hours 21 minutes every single day for the entire year. IMO "cost of electricity due to power consumption" really isn't something that needs to be factored into the equation, unless you live in Hawaii or another country where electricity costs significantly more.

Realistically I'd say anybody who isn't a full time pro gamer will have trouble gaming 4 hours per day for 365 days straight, so the cost difference due to using a 290 over 970 is likely to be even less than the 2 extremes presented above. Heck most weeks I spend more than $50 on meals alone! This is one end of the extreme, but if the person lives in Washington state where electricity is only $0.0715 per kWh, then the cost difference goes down to $10.44 per year, hardly anything to lose sleep over either way. The total power difference comes out to 146000W.Īssuming the person lives in Hawaii where electricity costs $0.3353 per kWh, then over the course of an entire year, he would end paying $48.95 extra for choosing to use a 290 over a 970. Now further assume that somehow said person manages to game 4 hours per day consistently for the entire year, so 365 days. So that's 400W of power difference in any given day. Now I don't know if the 290 was throttling or not, so for the sake of argument let's call the difference 100W.Īnyone who has a proper full time job and social life probably won't have time to game more than 4 hours per day on a consistent basis.
