Overclocking Affect on Power Consumption

[Mr. Tsao]

What is the average affect overclocking has on the power consumption of a GPU, specifically the new FinFET cards such as pascal and polaris (obviously info on polaris is limited)

overclocking pretty much nothing

overvolting is what increase power consumption

Hi! There's an equation that estimates differences in power consumption when overclocking. It goes like this:

 

P1: Stock Power

P2: OC Power

V1: Stock Voltage

V2: OC Voltage

C1: Stock Clockspeed
C2: OC Clockspeed.

 

So then to estimate OC power, we use the equation:

 

P2 = P1 * (C2/C1) * (V2/V1)^2

 

For Stock Power numbers, refer to reviews of the graphics card you've got.

 

Forum: If the equation isn't quite right feel free to correct.

the power consumption is exponentially related to the overclock

to change and discharge the cells you need energy and the faster you charge and discharge them the more energy you need, I don't believe there exists a precise formula that can be generalized for all components, but the one provided above is a very good estimate to prove the point and serve as an example of what to expect
