PS3 CPU "Cell Broadband Engine" The PS3 uses the Cell microprocessor, which is made up of one 3.2 GHz PowerPC-based "Power Processing Element" (PPE) and six accessible Synergistic Processing Elements (SPEs). A seventh runs in a special mode and is dedicated to aspects of the OS and security, and an eighth is a spare to improve production yields.
The Cell processor version used by the PlayStation 3 has a main CPU and 6 SPEs available to the user, giving the Gravity Grid machine a net of 16 general-purpose processors and 96 vector processors. The machine has a one-time cost of $9,000 to build and is adequate for black-hole simulations which would otherwise cost $6,000 per run on a ...
IBM doesn't specify the clock speed. The 45-nm Cell is 34 percent smaller and requires 40% less power than the original 65-nm processor according to earlier accounts.
A 120 GB Slim model Motorized slot-loading disc cover. This feature is absent in the Super Slim model. The redesigned version of the PlayStation 3 (commonly referred to as the "PS3 Slim" and officially branded "PS3") features an upgradeable 120 GB, 160 GB, [25] [26] 250 GB or 320 GB [25] [26] hard drive and is 33% smaller, 36% lighter and consumes 34% (CECH-20xx) or 45% (CECH-21xx) less power ...
The PlayStation 3 (PS3) is a home video game console developed and marketed by Sony Computer Entertainment (SCE). The successor to the PlayStation 2, it is part of the PlayStation brand of consoles. It was first released on November 11, 2006, in Japan, [16] November 17, 2006, in North America, and March 23, 2007, in Europe and Australasia.
Also residing within the main CPU, enables full screen, high quality FMV playback and is responsible for decompressing images and video into VRAM. [5] Operating performance: 80 MIPS [11] Documented device mode is to read three RLE-encoded 16×16 macroblocks, run IDCT and assemble a single 16×16 RGB macroblock.

The following is a chart showing the speed of reads and writes to the GDDR3 and XDR memory from the viewpoint of the Cell and RSX. Note that these are measured speeds (rather than calculated speeds) and they should be worse if RSX and GDDR3 access are involved because these figures were measured when the RSX was clocked at 550Mhz and the GDDR3 ...
