Apple UniNorth 2 AGP used in PowerPC 74xx Based Macs. Apple used their own type of northbridges which were custom ASICs manufactured by VLSI(later Philips),Texas Instruments and Lucent (later agere systems) List of Northbridge for PowerPC: IBM: CPC 700 and CPC 710 for IBM PowerPC 750 series. CPC 925 and CPC 945 for IBM PowerPC 970 series.
The POWER2 was a multi-chip design, but IBM also made a single chip design of it, called the POWER2 Super Chip or P2SC that went into high performance servers and supercomputers. At the time of its introduction in 1996, the P2SC was the largest processor with the highest transistor count in the industry and was a leader in floating point ...
The project was announced in 1999 when IBM and Nintendo agreed to a $1 billion dollar contract (IBM's largest ever single order) [1] for a CPU running at approximately 400 MHz. IBM chose to modify their existing PowerPC 750CXe processor to suit Nintendo's needs, such as tight and balanced operation alongside the "Flipper" graphics processor.
The first implementation of the architecture was the PowerPC 601, released in 1992, based on the RSC, implementing a hybrid of the POWER1 and PowerPC instructions. This allowed the chip to be used by IBM in their existing POWER1-based platforms, although it also meant some slight pain when switching to the 2nd generation "pure" PowerPC designs.
The PowerPC 970, PowerPC 970FX, and PowerPC 970MP are 64-bit PowerPC CPUs from IBM introduced in 2002. Apple branded the 970 as PowerPC G5 for its Power Mac G5 . Having created the PowerPC architecture in the early 1990s via the AIM alliance , the 970 family was created through a further collaboration between IBM and Apple .
In 1995, IBM released the Cobra, or A10 processor, the first full implementation of PowerPC AS, for the IBM AS/400 systems. It was a single-chip processor running at 50-77 MHz. It was designed with a semi-custom methodology, as a consequence of time-to-market constraints. The die contains 4.7 million transistors and measures 14.6 mm by 14.6 mm ...
The POWER4 is a microprocessor developed by International Business Machines (IBM) that implemented the 64-bit PowerPC and PowerPC AS instruction set architectures.Released in 2001, the POWER4 succeeded the POWER3 and RS64 microprocessors, enabling RS/6000 and eServer iSeries models of AS/400 computer servers to run on the same processor, as a step toward converging the two lines.
The PowerPC 602 was a stripped-down version of PowerPC 603, specially made for game consoles by Motorola and IBM, introduced in February 1995. [29] It has smaller L1 caches (4 KB instruction and 4 KB data), a single-precision floating-point unit [ 29 ] and a scaled back branch prediction unit.
