6 teraflops vs 1.23 teraflops for the base XBone is a 487% upgrade to the GPU. That's a generational leap IMO. Admittedly the CPU improvement is far more modest but the difference is massive. Remember the jump from the XBox 360 to the XBone represented a 512% increase in GPU power (.24 tflops vs 1.23 tflops) so the difference is nearly the same and the 360's lifespan was looooooooong and the hardware was grossly obsolete by the time XBone was released.
There is more to "power" than just flops.
There is more to "graphics" than just flops.
When a game only needs flops to draw an image on a screen and nothing else, then your blatant abuse of that one singular denominator might actually have some relevance.
Just remember you can have a GPU with more flops be slower than a GPU with less flops.
A generational leap usually brings with it a plethora of new graphics techniques, efficiency gains, multiples more Ram and an overhauled software stack.
Scorpio gets none of that. Ergo. It's not a generational leap.
