Like I said in the previous post of mine I referenced, it's usually the xx50 cards that tend to match (or slightly exceed) the current gen consoles from a theoretical performance standpoint.
Console teraflops:
- PlayStation 4: 1.84 teraflops. (2013), launch price $399
- Xbox One: 1.41 teraflops. (2013), launch price $499
x50 Nvidia card teraflops (the 9xx series was the first batch of cards developed and released
after the ps4/xbox one generation of consoles released):
- GTX 950: 1.825 Tflops (2015), launch price $159
- R7 360: 1.613 Tflops (2015), launch price $109
What is also important to note here is the fact that the GTX 950 performed ~50% better than its predecessor (the GTX 750ti) and was priced at just $10 more at launch.
The current GPU situation is not the same (even though cycle-aligned we are a year past the point of those aforementioned GPU's releasing) and will likely never will be.
This is what the steam hardware survey looked like at the end of 2015:
And at the end of 2016:
This is what it looks like now:
