The Processor upgrade card required the original CPU be plugged back into the card itself, and gave the machine the ability to run in its original 68040 configuration, or through the use of a software configuration utility allowed booting as a PowerPC 601 computer running at twice the original speed in MHz (50 MHz or 66 MHz) with 32 KB of L1 ...
PowerPC Macs cannot boot this OS as the backwards compatibility with them have been removed. This is also the final release with Rosetta, allowing PowerPC software to run on an Intel Mac. March 1, 2011: The beta version of the then-upcoming Mac OS X Lion removed "Rosetta" and lost the ability to run PowerPC based software. [53]
Common Hardware Reference Platform (CHRP) is a standard system architecture for PowerPC-based computer systems published jointly by IBM and Apple in 1995. Like its predecessor PReP, it was conceptualized as a design to allow various operating systems to run on an industry standard hardware platform, and specified the use of Open Firmware and RTAS for machine abstraction purposes.
This provides a convenient development environment for PowerPC-based real-time, embedded systems. Power.org has a Power Architecture Platform Reference (PAPR) that provides the foundation for development of Power ISA-based computers running the Linux operating system. PAPR was released in the fourth quarter of 2006.
Throughout the mid-1990s, PowerPC processors achieved benchmark test scores that matched or exceeded those of the fastest x86 CPUs. Ultimately, demand for the new architecture on the desktop never truly materialized. Windows, OS/2, and Sun customers, faced with the lack of application software for the PowerPC, almost universally ignored the chip.
The Apple–Intel architecture, or Mactel, is an unofficial name used for Macintosh personal computers developed and manufactured by Apple Inc. that use Intel x86 processors, [not verified in body] rather than the PowerPC and Motorola 68000 ("68k") series processors used in their predecessors or the ARM-based Apple silicon SoCs used in their successors.

Apple released a firmware update to reduce fan noise and offered a fan and power supply exchange program. [ 14 ] The last real update to the Power Mac G4 line came on January 28, 2003, offering dual 1.42 GHz PowerPC 7455 processors, with features not seen in previous DDR models: a built-in FireWire 800 connector, optional integrated Bluetooth ...
PowerPC G4 is a designation formerly used by Apple to describe a fourth generation of 32-bit PowerPC microprocessors. Apple has applied this name to various (though closely related) processor models from Freescale, a former part of Motorola. Motorola and Freescale's internal name of this family of processors is PowerPC 74xx.
