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
Northbridge chips are most commonly found on X86-based PCs, but they can also be found on other platforms, such as the PowerPC platform. A common example of a northbridge on a PowerPC platform is in Apple's older PowerPC-based computers like the iMac G5, which utilized an IBM CPC945 Northbridge chip.
The CPU itself can withstand 200,000 to 1,000,000 Rads and temperature ranges between −55 and 125 °C. The RAD750 packaging and logic functions has a price tag in excess of US$ 200,000 [ citation needed ] : the high price is mainly due to radiation hardening revisions to the PowerPC 750 architecture and manufacturing, stringent quality ...
The CPU can withstand an absorbed radiation dose of 2,000 to 10,000 grays (200,000 to 1,000,000 rads), temperatures between −55 °C and 125 °C, and requires 5 watts of power. [ 1 ] [ 3 ] The standard RAD750 single-board system (CPU and motherboard ) can withstand 1,000 grays (100,000 rads), temperatures between −55 °C and 70 °C, and ...
Pegasos 2nd version (G4), inner view Pegasos II motherboard Version 1.0 (2B3). The Pegasos II uses a Marvell Discovery II MV64361 northbridge, removing the need for the "April" chipset fix on the previous model, and additionally offers integrated Gigabit LAN and DDR support, and the ability to use the Freescale "G4" processor line.
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 .
Processor power dissipation or processing unit power dissipation is the process in which computer processors consume electrical energy, and dissipate this energy in the form of heat due to the resistance in the electronic circuits.
The PowerPC e5500 is a 64-bit Power ISA-based microprocessor core from Freescale Semiconductor. The core implements most [ 1 ] of the core of the Power ISA v.2.06 with hypervisor support, but not AltiVec .
