| | XBOX 360 vs. PS3: an in depth lookWritten by Tony James
All gamers are awaiting release of Xbox 360 and PS3. This article takes an in depth look at how two systems compare.Graphics: Everyone has seen an Xbox and a PS2 in action and we are all waiting to see which of two next generation consoles for two systems will have edge when it comes to graphics. We have all seen screenshots of games on two systems but what about actual gameplay graphics. Despite hot debate, when you look at numbers two systems use a different but equally effective method of delivering graphics processing power. The XBOX uses a custom ATI processor with 48 graphics pipelines and PS2 has a custom NVIDA graphics processor with an estimated 24 pipelines. The numbers are misleading because PS2 piplines are more powerful than XBOX pipelines. In end two different graphics processors will deliver about same amount of power, we can expect to see impressive results from both sides. Games: Both systems have several franchise titles such as Halo2 for XBOX and Gran Tourismo for PS2 that you will see in next generation systems, but what other games can you expect to see. If you are a fan of genres such as role playing that are dominated by Japanese and other foreign developers such as Square, you should look forward to PS3. There is no indication that XBOX 360 is going to gain much more support from foreign developers and buyers than original XBOX. An article on GameSpot.com reports that only two percent of Japanese gamers are interested in buying an XBOX 360, with sixty percent looking forward to PS3 and eight percent to Nintendo Revolution. Overall you can expect to see more games on PS3 than XBOX 360, reflecting selection for current generation systems. Only time will which console will have quality of games which all of us are been expecting Media Type: Will media storage type be a factor in quality of games? Since PS3 is owned by Sony and BLUray is Sony’s next high definition storage medium, PS3 games will be stored on BLUray discs which hold approximately 54 gigs. The Xbox 360 games will be stored on Double Layer DVDs which store 9 gigs. Obviously BLUray discs can store a lot more data, but at current stage of game development, any game developed will fit just as well on 9 gig DVDs, so this is not a major factor but one that may come into play later on. Processing Power: How do two systems compare when looking at brute processing power? The PS3 uses a Cell processor with a PowerPC-based core with seven synergistic processing units while 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 number of dot product calculations per second 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 Xbox can handle 33.6. There is a debate over which system has more brute processing power and these numbers can be confusing to average person, but overall it seems that PS3 has an edge over Xbox when it comes to overall processing power.
