The PlayStation 4 will not use Sony’s Cell processor nor any possible successor to the vaunted chipset that was introduced to the world through the PlayStation 3. Cell was not what Sony hoped that it would be. It never managed to make the PS3 appear to be significantly more powerful than the Xbox 360. AMD might engineer the main processing and graphics chips for the machine. If AMD does, they could use the AMD Fusion architecture, which would put CPU and GPU on the same chip. A rep from Sony declined to comment on this story, citing the company’s policy not to comment on rumors and speculation. Even though Sony hasn’t acknowledged the existence of the PlayStation 4, we are beginning to hear trickles of information about Sony’s next gen.
