Specific Northbridge IC must be used for PowerPC CPU. It is impossible to use Northbridge for Intel or AMD x86 CPU with PowerPC CPU. However it is possible to use certain types of x86 Southbridge in PowerPC based motherboards. Example: VIA 686B and AMD Geode CS5536. Apple UniNorth 2 AGP used in PowerPC 74xx Based Macs
The name is derived from drawing the architecture in the fashion of a map. The CPU would be at the top of the map comparable to due north on most general purpose geographical maps. The CPU would be connected to the chipset via a fast bridge (the northbridge) located north of other system devices as drawn. The northbridge would then be connected ...
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 .
For this reason, the IBM PowerPC desktops did not ship, although the reference design (codenamed Sandalbow) based on the PowerPC 601 CPU was released as an RS/6000 model (Byte ' s April 1994 issue included an extensive article about the Apple and IBM PowerPC desktops). Apple, which also lacked a PowerPC based OS, took a different route.
The PowerPC 400 family is a line of 32-bit embedded RISC processor cores based on the PowerPC or Power ISA instruction set architectures.The cores are designed to fit inside specialized applications ranging from system-on-a-chip (SoC) microcontrollers, network appliances, application-specific integrated circuits (ASICs) and field-programmable gate arrays (FPGAs) to set-top boxes, storage ...

The PowerPC 7xx is a family of third generation 32-bit PowerPC microprocessors designed and manufactured by IBM and Motorola (spun off as Freescale Semiconductor bought by NXP Semiconductors). This family is called the PowerPC G3 by Apple Computer (later Apple Inc. ), which introduced it on November 10, 1997.
The PowerPC e500 is a 32-bit microprocessor core from Freescale Semiconductor. The core is compatible with the older PowerPC Book E specification as well as the Power ISA v.2.03 . [ citation needed ] It has a dual issue, seven-stage pipeline with FPUs (from version 2 onwards), 32/32 KiB data and instruction L1 caches and 256, 512 or 1024 KiB L2 ...
