The PlayStation 3 (abbreviated PS3) is Sony's seventh generation era video game console in the PlayStation series. It is the successor to the PlayStation 2 and will mainly compete against Microsoft's Xbox 360 and Nintendo's Wii.

Sony has stated that the PlayStation 3 will have backward compatibility with the PlayStation and PlayStation 2, and that every PS1 and PS2 game that observes its respective system's TRC (Technical Requirements Checklist) will be playable on PS3 at launch.

Contrary to previous reports that PlayStation 2 emulation would be accomplished through software,[citation needed] the July issue of Japanese magazine Ultra One reports that the current design of PlayStation 3 includes the core PS2 chipset.

The PlayStation 3 does not include interfaces for legacy PlayStation devices such as the DualShock controller. It is not known at this time whether USB devices for PlayStation 2 will be compatible with PlayStation 3.

Central processing unit (CPU)

3.2 GHz Cell processor: 1 PowerPC-based "Power Processing Element" and 7, 3.2 GHz Synergistic Processing Elements (SPEs). The PPE has a 512 KB L2 cache and one VMX (AltiVec) vector unit. Each of the eight SPEs is a RISC processor with 128-bit 128 SIMD GPRs and superscalar functions. Each SPE has 256 KB of L1 cache/software-addressable 4.8 GHz SRAM, called the "Local Store".

Only seven SPEs are active; the eighth is redundant, to improve yield. If one of the eight has a manufacturing defect, it is disabled without rendering the entire unit defective. Additionally, one of the seven active SPEs is reserved for use by the system's OS, leaving six SPEs directly available to applications.
