That's really not the point, the point is what's possible at the latest fab scales, you made a claim that AMD's next APUs for 2016 could perform as well or better than PS4's SOC and run on 15 watts. NVidia's designs of GPU tend to be more efficient than AMD's.


Based on what?  Maxwell is more efficient than AMD's ~2 year old GPU's.   LOL big deal!  AMD's new line-up is out in 3 months so wait till then and we can talk.

 

As for history, Nvidia has by no means been an efficiency leader:

HD 5000 >>> GTX 400

HD 6000 >> GTX 500

HD 7000 >= GTX 600

R9 200 = GTX 700

R9 300 ? GTX 900


Based on the most important factor when it comes to efficiency, namely performance per watt.

GTX 900 should be compared to R9 200, they're both 28nm parts, yet NVidia's tech performs vastly better for the same or even lower levels of energy.

GTX 980 runs on like 165 watts, yet it vastly outperforms an R9 290x, meaning it's absolutely the more efficient card.

 

As things stand right now NVidia are far ahead, they release actual hardware revisions more often than AMD, they will be releasing a completely architecture next year in Pascal.

 

The only thing AMD has on Nvidia is cost, but they don't have a card on the market that will compare to the performance per watt of Nvidia's offerings, it's just a fact.
