What is the difference between PS3 games and PS2 games?

Answer 1

PlayStation 2 format games are either CD-ROM (blue or clear) or DVD-ROM (clear) and are rendered using a graphics synthesizer clocked at 147.456 MHz with a floating point performance of 6.2 Gflop/s along with a 2mb sound memory. Playstation 3 format games have only one medium which is Blu-Ray disk (BD-DVD) and are rendered using a graphics processing unit made by Nvidia, the RSX 550 clocked at 550MHz with a floating point performance of 1.8 Tflops/s along with its cell-based sound processing.
