PowerPC 970

The PowerPC 970 and PowerPC 970FX , so known under the name of PowerPC G5 , are Microprocesseur S RISC 64 bits of the family PowerPC. Conceived by IBM and Apple, they derive from the processors POWER 4 of IBM. They integrate the vectorial calculating unit AltiVec already used for the PowerPC G4. Although nativement in 64 bits, PowerPC G5 also nativement support the instructions 32 bits.

Characteristics

Launched in 2002, the PowerPC 970 are engraved in 130 Nm and functioned at the origin at frequencies from 1,4 to 1,8 GHz. They integrate 58 million Transistor S. a processor into 2 GHz left in 2003.

The PowerPC 970FX left in 2003 and turn at frequencies between 1,6 and 2,7 GHz. They are engraved in technology 90 Nm what enables them to release less heat than PowerPC 970. They integrate also 58 million Transistor S.

The PowerPC 970GX has a mask of level 2 of 1 Me, against 512 Kio for the FX.

The PowerPC 970MP is a dual-core processor, left to the current the third quarters 2005. It reaches a frequency of 2,5 GHz and is engraved in 90 Nm, then later in 65 Nm. The 970MP equipped the last Power Mac G5.

Use

Currently, PowerPC 970 are mainly used in the waiters IBM and in the computers Power Mac, Xserve and IMac of Apple left until in 2005. G5 is the name given by Apple to PowerPC of the family 970, which refers to the fifth generation of PowerPC.

PowerPC 970 are also used in the supercomputers. In November 2004, a supercomputer containing PowerPC 970 was the 5th most powerful computer of the world and a cluster of Xserve G5 was 14th the more powerful ( Source : top500.org). The cluster of G5 are characterized by their low costs and thus their performance ratio/price much higher than the other supercomputers.
