PlayStation 4 Announced: PC-based AMD Hardware Inside
*********************************************EXCERPT*************************************
Sony says that the PS4 has been in development for five years, which is a bit surprising as the PS4 is based on x86 architecture with 8 cores, an integrated GPU, and 8GB of shared GDDR5 RAM. Sony used the word APU, which gives us pretty good confirmation that it's AMD inside. The graphical portion of the APU is said to deliver almost 2 TFLOPS of performance. The 8GB of unified memory is shared between the CPU and GPU and supplies over 170GB/s of bandwidth.
I am not interested in buying one unless it runs Linux or provides a PC like capability.
