PraetorXyn posted...The reason the PS4 cannot do this is because the PS3's Cell processor was a PowerP-based architecture, which is COMPETELY different than the x86-64 architecture for the PS4. This was a very good move, as the thing that hurt the PS3 the most was that was so difficult to develop for compared to PC/360 because of it's screwed up proprietary architecture.
The 360 is PowerPC-based too, however much more conventional than the Cell. The ease of porting was due to MS sharing APIs between console and PC with XInput, Direct3D 9, Xbox / Windows Live and so on being available for both platforms.
The jump from PS3 to PS4 is an equivalent shift in architecture to Xbox to 360, but in reverse (PowerPC to x86). However, where the Xbox was considerably less powerful than the 360 and could be software emulated, the PS3 and PS4 are much closer on raw processing power.
