**United States: Electricity costs in each state:**http://www.eia.gov/electricity/state/

Above are the electrical costs in each state in cents per kilowatt hour. One kilowatt is 1000 watts. This is how many cents are charged for using a constant 1000W of power for one hour. Hawaii is the most expensive with 34 cents per kilowatt hour.

__Nvidia GTX 980Ti vs AMD R9 Fury X__**Gaming Conditions**

According to Nvidia's website here, the GTX 980Ti is labelled as 250W. The Tomshardware review shown here says it draws in an average of 233W under gaming load. The Guru3D review of the 980Ti here labels it at 250W. The non-reference MSI GTX 980Ti Lightning review here on Guru3D shows it draws in 302W, 52W more than the reference. The Techpowerup review here labels it at 211W under average gaming load. Contrarily, the MSI 980Ti Gaming review shown here shows it to consume 262W of power. This averages to

**252W**.

AMD's website does not list power consumption. The Tomshardware review here shows the Fury X to draw in 221W on an average gaming load. This is lower than the GTX 980Ti. On the contrary, the Fury X when stress tested does draw in more power. The Guru3D chart here contrarily shows the Fury X to draw in 294W. Those are two very different values. It may be that in the Tomshardware review the GPU was not stressed at 100%, whereas it may have been in Guru3D's review. This one requires more research. Techpowerup's review here has average gaming load as 246W. This averages to

**254W**.

Considering high similarities between the Fury X and 980Ti power consumption, calculating any difference in power consumption is trivial, because in this scenario it will depend on the specific 980Ti being compared to. As can be seen, the non-reference MSI 980Ti cards draw in far more power than the reference, but any assumptions can not be made when comparing the power consumption of the two cards. Undoubtedly, the Fury X draws in more power under a stress test, but under gaming load it tends to vary review to review.

__Nvidia GTX 980 vs AMD R9 390X__**Gaming Conditions**

According to Nvidia's website here, the GTX 980 is labelled as a 165W card. The Tomshardware review here of the Windforce GTX 980 shows it drawing in 186W while gaming. The Guru3D review here shows the reference to be around 171W while the Gigabyte G1 is 191W. This brings it to an average of

**178W**.

AMD's website does not list power consumption for cards. The Tomshardware review of the MSI R9 390X here shows it drawing in an average 292W while gaming. The Guru3D review here has it at 258W. Considering the large difference there, I dug deeper and found the Guru3D review on the Asus Strix 390X here which labels the card at 289W. PCworld here shows the Asus Strix to draw in 275W of power. The average of these is

**279W**of power under load.

__Nvidia GTX 970 vs AMD R9 390__**Gaming Conditions**

According to the official Tomshardware review on the GTX 970 and 980 here, the Windoforce GTX 970 consumes about 179W while gaming. Nvidia's reference model is labelled as 145W on their website here. So, let's say a minimum is 145W and maximum is 180W. The GTX 970 will operate somewhere within that range. Guru3D has it labelled as 168W here. Point be told, it is within that vicinity. The average of these 3 results in a

**164W**power consumption average while gaming.

The R9 390 power consumption is not labelled on AMD's website. According to Tomshardware's review here on the Sapphire Nitro R9 390, the power consumption is

**255W**under a gaming load. Unfortunately, I cannot find other reputable sources online for the 390, as I only see 390X reviews, so we'll have to stick with this.

__Nvidia GTX 960 vs AMD R9 380__**Gaming Conditions**

According to Nvidia's website here, the GTX 960 consumes 120W of power. According to Tomshardware's review here, average GTX 960 power consumption while gaming of various cards is 99.5W of power. According to Guru3D, the GTX 960 consumes about 123W of power under load, which is far closer to Nvidia's specification than the Tomshardware review. If the 3 are averaged, we get

**114W**of power draw under gaming load.

AMD does not include TDP on their site for their cards. According to the Tomshardware review of the MSI R9 380 here, the 380 draws in an average of 185W while gaming. According to the Guru3D review of the Asus Strix R9 380 here, the R9 380 consumes 196W under gaming load on average. If we average these two, we get about

**191W**of power consumption. The difference in the GTX 960 and R9 380 power consumption is proportionally greater than the difference in GTX 970 and R9 390 power consumption.

*Conclusion*The GTX 950 has barely any electric bill savings over the R7 370. The 370 on average uses only about 10 more watts than the 950, so the savings are extremely minimal. Of AMD's 300 series cards, the 370 is undoubtedly the most efficient for its performance. When getting into the high-end cards such as the R9 390 vs the GTX 970, going with the GTX 970 will save one around $30 after two years. Usually after two years, someone gets a new card.

The 980Ti compared to the Fury X was the most difficult to find accurate information on. 980Ti power consumption ranged from the low to high watts. When all was averaged out, the Fury X and 980Ti came very close in power consumption. The Fury X does use more power, and is slightly less powerful than the 980Ti. However, it is still the victor below, as Fiji did a great job of lower power consumption.

When comparing the GTX 980 vs 390X to the GTX 970 vs 390, the results are very similar. Both the 980 and 390X use little more power than the cards below them, and considering the 25-30% performance difference between 980-970 and 390X-390, along with the 11% money savings increase, the 390X is actually one of the best AMD cards in terms of power competing. The 380 failed the most. The following outlines the best AMD cards (power-wise) when compared to the other cards, performance differences, and Nvidia counterparts:
