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.
"PowerPC 630" was the early name for the high end 64-bit PowerPC processor, designed by IBM to unify the POWER and PowerPC instruction sets. It was later renamed " POWER3 ", probably to distinguish it from the more consumer oriented "PowerPC" processors used by Apple .
Dual 375 MHz IBM POWER3-II processors on the CPU module of a RS/6000 44P 270. The POWER3 is a microprocessor, designed and exclusively manufactured by IBM, that implemented the 64-bit version of the PowerPC instruction set architecture (ISA), including all of the optional instructions of the ISA (at the time) such as instructions present in the POWER2 version of the POWER ISA but not in the ...
The POWER3 began as PowerPC 630, a successor of the commercially unsuccessful PowerPC 620. It uses a combination of the POWER2 ISA and the 32/64-bit PowerPC ISA set with support for SMP and single-chip implementation.
The PowerPC specification is now handled by Power.org where IBM, Freescale, and AMCC are members. PowerPC, Cell and POWER processors are now jointly marketed as the Power Architecture. Power.org released a unified ISA, combining POWER and PowerPC ISAs into the new Power ISA v.2.03 specification and a new reference platform for servers called ...
The Macintosh Quadra 630 (also sold as the Macintosh LC 630 and Macintosh Performa 630) is a personal computer designed, manufactured and sold by Apple Computer from July 1994 to March 1996. It was introduced as the replacement for the Quadra 610 , and was the least-expensive computer in the Macintosh lineup with prices starting at $1,199 USD .
Speed-bumped versions of the Power Macintosh line were introduced at the beginning of 1995, followed in April by the first PowerPC 603 models: an all-in-one model called the Power Macintosh 5200 LC and a replacement for the Quadra 630 called the Power Macintosh 6200.
The ISA evolved into the PowerPC instruction set architecture and was deprecated in 1998 when IBM introduced the POWER3 processor that was mainly a 32/64-bit PowerPC processor but included the IBM POWER architecture for backwards compatibility. The original IBM POWER architecture was then abandoned.
