So that demo was run on an AMD 7900 Graphics card? That transfers 2,176 Gfloss of Data right?
PS4's Graphics Card is capable of 1,840 Gflops (Which is about as powerful as a 7850-7870).
This means that the PS3 version will be about 90% as good as that video, not bad. Wait! Was the demo on a 7900 or a 7990? There is a big difference, a 7990 has 6,963 Gflops of data, which would put the PS4 version running at 30% of the demo's capabilities.

For reference, the 1st number represents the series humber (7th series) and the second number represent the .... power level? So the PC is at 9, the PS4 is at 8. The other two numbers I think are like update numbers ( Like version 1.1, 1.2, etc)
Also X-Box and PS3 are about 240Gflops, so let's see how they turn out with just over 10% the graphical power.

Funny, I don't see a HUGE jump this gen, despite PS4 being nearly 9x more powerful then the PS3.

I would argue that PS4 is much more than 9x more powerful than PS3 (RAM, alone, jumped x16). Besides, as always mentioned, launch games won't tell the full story.

The PS4 is roughtly 10-15 times stronger than the PS3.

How? The amount of processing power of the PS4 is only 9x more. I know RAM jumped 16x, but other things like the GPU speed doesn't even double from PS3 to PS4 (from 550 MHz to about 860 Mhz). I also know the GPU bandwidth only increased 3x (54 to 154 GB/s) and from what I hear the bandwidth was one of the bottlenecks of the PS3 (Id bandwidth related to bus speed? I heard the PS3 has a slow bus speed and that's why newer model PS3's couldn't emulate PS2 games properly).
I don't know too much about computers, but I know that more RAM =/= more power after you reach the point where the RAM is sufficient and no bottlenecking the system. 16x RAM is sufficient for 9x more processing power.
