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.

Comparing clock speed of GPUs is pointless. PS3 VRAM had 22.4 GB/s of badwidth and the PS4 has 176GB/s unified which is an almost 8x increase. Memory bandwidth wasn't nearly as much of an issue as having 2 small pools of RAM, the split pools is what caused games like Skyrim to have it's issues where as not having an embedded framebuffer like the PS2 and 360 at worst caused some lower quality alpha blending and lower quality AA until MLAA/FXAA became popular.

Okay so the VRAM bandwidth increased 8x, GPU Bandwidth increased 3x, Raw Processing Power (What would you call GFLOPS?) increased 9x, GPU Speed increased 1.6x, but because RAM increased 16x the PS4 is 10-15 times more powerful then the PS3 instead of 9x or less powerful?
I don't understand, RAM wouldn't make the PS4 go from 8x as powerful to 12x as powerful, no matter how good it is, it's not needed, something else will bottleneck the system.
