because its only using 80% of the total wattage calculated, or total wattage pool. 120w is 80% of 150w. So youre calculating it incorrectly just as they have done. Thats strictly full TDP. Before we even touch on performance. So 150w is 100% of the pool of power that we are rating. The 1060 uses 120w. Its 20% more power effecient
And where does 1.15 come from?
Dividing 150/120 gives us no number related to power efficiency. The original graph is incorrect because it was calculated incorrectly. Working it backwards and then typing it out seems right at first. Its not. Unless Im missing something here. Im open minded to being totally wrong but this seems way too easily identifiable as incorrect.
If the cards had the same performance and same electricity consumption. Efficiency is 1.
E.g 120 watts divided by 120 watts divided by the equal performance would act as a modifier of 1.
However if one card uses 30 less wants. That means one card is 25 percent more efficient.
Even. 150 divided by 120.
1.25 I.e 25 percent more efficient. However of this card also performs 15 percent better while consuming 25 percent better it acts as a modifier.
I.e 1.15. IF IT performed the same this modifier would be 1 but since it's performs 15 percent better, this becomes 1.15.
There for to get the efficiency you have to multiply both numbers.
1.25 * 1.15 = efficiency.
