Sony is one of the world’s largest multinational conglomerate corporation that electronics, communications, video game consoles, video and information technology products. Among these products we should keep an eye on video game consoles because PlayStation is the product that makes many a lot of money to Sony. PlayStation gets a good feedback from the gamers, so PlayStation is manufactured and upgraded continually. The PlayStation can be divided into three types according to performances.
The first category is low performance. The example is a PlayStation 1 that was launched in 2000. It is the first version of PlayStation video game console. The PlayStation 1 has a beautiful body and Graphical User Interface (GUI) menu. A GUI is a type of user interface which allows people to interact with electronic devices such as computers, MP3 Players, Portable Media Players or Gaming device household appliances and office equipments. In addition, it added a protection against the modchip. The PlayStation 1 used a CD –Rom for disc media. The CPU is 32 bit and its capacity is 30 MIPS [Million Instructions Per Second]. The graphics has 16.7 million colors and 360,000 polygons/sec displaying rate. The main Random Access Memory is 2 megabytes and the VRAM is 1 Megabyte. The sampling frequency of sound is 44.1 KHz and the sound ram is 512 K.
The second category is medium performance. It is a PlayStation 2 that is backward compatible with its predecessor. It can play almost every PlayStation game. It embeds the most important part of the PS1 inside the PlayStation 2 which is called the IOP, that is used for input and output such as memory card, DVD drive, network and hard drive. The disc media of PlayStation 2 are CD and DVD. The CPU is128 bit custom multi-media Emotion Engine chip. Furthermore, the graphic is better in 2D and 3D games. The graphic processor unit is 150 MHz, called Graphics Synthesizer. Besides that, the PS2 can play most disc media such as all original PlayStation games, DVD movies, and audio CDs. The output frequency is 48 KHz and 2MB sound memory. Moreover, there are 48 channels with 3D surround sound. The sound memory is 2 MB and the main memory is 32 MB.
The third category is high performance. It is PlayStation 3 that is the third generation of PlayStation. The PlayStation 3 is backward compatible with all games that made for PlayStation 1 originally. It uses a high –definition optical disc format that is Blu-Ray Disc. The PlayStation 3 is the first product that applies the Blu-Ray player on the market. It uses 3.2 GHz “Cell Broadband Engine” as CPU. The graphics processing are handled by the NVIDIA RSX called reality synthesizer which can output resolution from 480i/576i SD up to 1080p HD. The PlayStation 3 has the PlayStation network that is unified online gaming service so, it can connect with PlayStation Portable. The capacity is 40-120 GB. The PlayStation 3 Games are full 3D games. The sound is Dolby 5.1 with 3.2 GHz. The main ram is 25.6GB/s and the VRAM 22.4 GB/s.
In my opinion, PlayStation 3 has the best graphics processor unit because it has many functions that are better than PlayStation 1 and PlayStation 2. The successes of PlayStation3, PlayStation 2 and PlayStation 1 are still popular and have high circulation. By the way, I think that “PlayStation 3 is the next generation video game console that will not be obsoleted in the next 10 years.”
