next gen vs current gen assassin's creed 4 black flag

Next gen is powerful for the game which give a vast detail of the game and create a new world for the game.
As the next gen starts with the ps4,xbox one,wii u.
With reveal of ps4 the gamer has a huge comparing with xbox one.
Many debates about which game stands strong in the world of game.But the answer was not simple about the games.As of 2013 ubisoft show assassin's creed 4 black flag which was in every platform.
When we compare with the system like xbox 360,ps3 ,wii u,xbox one ,ps4.

The power of xbox 360 is

CPU	3.2 GHz PowerPC Tri-Core Xenon

Graphics	500 MHz ATI Xenos

The power of  ps3 is 

CPU	3.2 GHz Cell Broadband Engine with 1 PPE & 6 SPEs

Graphics	550 MHz NVIDIA/SCEI RSX 'Reality Synthesizer'

The power of  wii u is

CPU	1.24 GHz Tri-Core IBM PowerPC "Espresso"

Graphics	550 MHz AMD Radeon "Latte" GPU

The power of xbox one is 

CPU	Custom 1.75 GHz AMD 8 core APU(2 Quad-Core Jaguar modules)

Graphics	853 MHz AMD Radeon GCNarchitecture (inside of APU)

The power of ps4 is

CPU	Semi-custom 8-core AMD x86-64 CPU (integrated into APU)

Graphics	Semi-custom AMD Radeon GPU (integrated into APU)

There is nothing much difference between the xbox one and ps4 graphics But ps4 has more light effect some gamer like it other will hates it.And ps3 and xbox 360 lies in low graphics only in plant and smoke. wii u cannot stand more for next gen because it look more than current gen not that same of next gen.I think next gen has not make much improvement but assassin's creed 4 black flag has make a huge improvement but it not look like assassin creed moreover it look pirates. You can get more than 30 hours of gameplay.

                               Thanks and stay tune for more next gen.
