As A Result Of The Die Shrink From 28 To 16 Nm, Pascal Based Cards Are More Energy Efficient Than Their Predecessors.
If its not too urgent i'd recommend waiting a couple months for the inevitable new x70 card. Nvidia geforce gtx 1070 ti. The gtx 1070 is nvidia’s second graphics card (after the 1080) to feature the new 16 nm pascal architecture.
The Gtx 1070 Is Rated At Just 150 Watts.
The 1070 is slightly faster than the 980ti. Witcher (1440p, ultra, aa) gtx 970: And since it's a newer card, it will be supported for longer(drivers etc).
In Terms Of Performance The Gap Between The Flagship 1080 And 1070 Averages 25%.
If you play mainly dx11 games, 980ti oc to oc is 7% faster in this case, however with async, gtx1070 beat the 980ti by 2.5%. The gtx 1070 is rated at just 150 watts. While 980 is only faster if compared to fury x.
It Might Be Due To The Fact That The 980Ti Has A Wider Bus And The 1070 Only Has A 256Bus.
I expect it to perform better than the 980ti in future games as well. But the 1070 is a bit faster and has newer tech, like vr capabilities the 980 ti lacks. When that is said, it's not a huge difference, and if i were in your shoes, i'd probably return the 1070 and pay the difference to get a 1080.
The 1070 Has 3.7Fps More?
As a result of the die shrink from 28 to 16 nm, pascal based cards are more energy efficient than their predecessors. So its really depends on what you going to play and the price which is good for you. Between new games that better utilize modern gpus and nvidia's focus on driver optimizations for turing, the rtx 2060 has been able to further distance itself from the gtx 1070 and consequently.
