For the more technically challenged among us, assuming the leaked specs are at least ballpark true, would the jump from the PS4 to the Neo be as profound as say, 360 to One or PS3 to PS4? Roughly?
Sony say that the PlayStation 4 is 10x as capable as the PlayStation 3, it would be roughly the same from the Xbox 360 to the Xbox One as-well, as-well as having 16x the memory. I'm not 100% certain about the CPUs, but I do know that they are a lot faster.
The jump from the PlayStation 4 to the Neo with the rumored 4.2 teraflop specs is around 2.3x.
For the Xbox One to Scorpio we're looking at a machine which is roughly 4.6x faster, so pretty much half of the last gen to current gen jump in power, a 6 teraflop Neo would be 3.2x because of the power difference of the XBO and PS4.
The performance boost doesn't look very exciting when compared to the PS3 to PS4 jump, that's kind of why this is looked at as a half generation.
One thing to remember though is that most PS4 games run between 900p and 1080p, whilst the majority of the PS3 games were running at 720p, that's a 2.25x pixel count increase with a power jump of 10x, if the Neo has the option of running games at the same resolution the additional power is going to be a great benefit in comparison to the PS4.
Naughty Dog pulled of Uncharted 4 on a 1.84 teraflop GPU, and this game is arguably the best looking game to date, it would be incredible to see what they could do with a 4.2+ teraflop machine.
It would be nice to have a more powerful machine though, I believe a 5 teraflop GPU is plausible but anymore then that is kind of pushing.
