PS3 vs XBOX 360

Media Types:
Since PS3 is owned by Sony and BLUray is Sony’s next high definition storage medium, the PS3 games will be stored on the BLUray discs which hold approximately 54 gigs. The Xbox 360 games will be stored on Double Layer DVDs which store 9 gigs. Obviously the BLUray discs can store a lot more data, but at the current stage of game development, any game developed will fit just as well on the 9 gig DVDs, so this is not a major factor but one that may come into play later on.


Processing Power:
How do the two systems compare when looking at processing power? The PS3 uses a Cell processor with a PowerPC-based core with seven synergistic processing units while the Xbox comes with a Custom IBM PowerPC CPU with three dual-threaded cores that can handle six total threads at a time. An important comparison to look at is the number of dot product calculations per second the systems can perform. The reason this number is important is because it is used extensively during gameplay in 3d math to calculate various things such as vector lengths, projections, transformations, and more. Both systems are clocked at 3.2 Ghz. The PS3 can handle 51-billion dot product operations per second and the Xbox can handle 33.6. There is a debate over which system has more brute processing power and these numbers can be confusing to the average person, but overall it seems that the PS3 has an edge over the Xbox when it comes to overall processing power.

Controllers:
The controllers on the two systems retain the basic shape from the original systems with some modifications. The PS3 controller has the most dramatic change; it has a streamline shape that looks more like a stealth airplane than a game controller. The XBOX controller is basically the same shape as the previous system with a different color scheme. From the pictures released, it seems the XBOX controller will be more comfortable and natural to use.

Graphics:
Both systems have fairly similar graphics but the Xbox 360 has better lighting while the PS3 has sharper textures. The 360 has better high dynamic range lighting, but the building textures are sharper on the PS3.

However, The final choice comes down to personal preference.
