Gfx yearly power ( Watt )

[ollioddi]

Hi

 

Anyone knows what the 145 watt (gtx 970) is per? Is it per hour, day, or watt?(See what i did?)

 

Also if anyone knows what it would cost (Yearly in usd) to run a gtx 970, and a gtx 780 (Versus comparison)

 

Thanks in advance

Are you seriously asking what is the watt?

To clarify the watt is defined as the work/time. So it is already in the units of energy consumption.

How much energy the 970 uses is based off how long you keep it active and at what % load. This and several other values will change how much energy the 970 uses.

If you want to know how much it will cost you use the TDP as an estimate of energy consumption then multiply it by the # of seconds you plan on using the 970 at max load. Then divide that by the power cost of electricity to see how much it will cost you in the specific # of seconds or your time frame. Do the same for a 780 and subtract to get your delta difference in cost. Note that this would be the most optimistic for how much you spend as gpu use more than there stated TDP.

Watt = Joule/sec

 

It shouldn't be something you need to worry about, the difference in cost shouldn't be that big.
