Sony PS3 was launched in 2006 using a GPU based on GeForce 7900 GTX (based from 7800 GTX of 2005)
i guess they were just sticking to the (at the time) make loss on hardware / profit with software business model.
Sony PS4 was launched in 2013 using a mid-range GPU (HD 7850) from an AMD GPU architecture of 2011. The PS4 is just a year old and it can't even run games at 1080p 60FPS
so then now, i think, in the aftermath of the very long previous gen:
- they're trying to trim costs (having that 10-year cycle helped here too)
- perceived diminishing returns in terms of graphics. they're like - why go higher end when the mid-range setup already satisfies the customers? console players don't worry about having inferior graphics to pc as long as they don't have something to compare with.
