He meant the GTX 690 (2x 2880 gigaflops) versus the Xenos' 240 gigaflops. I don't really think that's a comparison meaningful on any aspect.

Anyways a hypothetical GTX 6800 Ultra SLI from 8 years ago would be too 24 times less powerful than the GTX 690. That's more than five Moore cycles ago (32-40 times improvement), so Nvidia is getting a bit sloppy huh.

not really it's just more transisters are put into things like cache and other components that don't actually conribute directly to the theoretical floating point calculations per seccond metric.

Even then transistor count didn't increased as it should though. The discrepancy is more likely related to both the inability of the power consumption and heat dissipation to follow the possible increase in performance and the difficulties of some semiconductor manufacturers to keep miniaturizing as efficiently as the market would demand. Of course there's still improvements on the architecture to consider anyways.
