Power Macintosh

1980

Of the alliance, John Sculley said, "The Macintosh strategy paid off very well for us in the 1980s, but we didn't think we could establish the next generation of computing by using that model in the 1990s.

1987

as the core of the Macintosh brand from March 1994 until August 2006. Described by MacWorld as "The most important technical evolution of the Macintosh since the Mac II debuted in 1987", the Power Macintosh is the first computer to use the PowerPC CPU architecture, the flagship product of the AIM alliance.

The decision to use RISC architecture was representative of a shift in the computer industry in 1987 and 1988, where RISC-based systems from Sun Microsystems, Hewlett-Packard, and IBM were significantly outpacing the performance offered by systems based on Motorola's 68020 and 68030 processors and Intel's 80386 and 80486 CPUs.

1989

The company lacked the financial and manufacturing resources to produce a working product and the project was cancelled in 1989. By early 1990, Apple was in contact with a number of RISC vendors to find a suitable hardware partner.

After Gassée left Apple in early 1990, the goal of the Jaguar project was refocused to be a mainstream Macintosh system instead of a new platform.

Of the alliance, John Sculley said, "The Macintosh strategy paid off very well for us in the 1980s, but we didn't think we could establish the next generation of computing by using that model in the 1990s.

By the early 1990s, the networking industry was coalescing around the 10BASE-T connector, leading Apple to include this port alongside AAUI in mid-1995, starting with the Power Macintosh 9500.

1991

By January 1991, the engineering team had produced a prototype of a Macintosh LC with its 68020 CPU being swapped out for an 88100 and a 68020 emulator.

The Jaguar project was folded into the Macintosh team in early 1991.

Working with IBM, and making it available to everyone, we can have a much wider impact with these technologies than we did with the Macintosh." Development of the PowerPC 601 chip started in October 1991 and was completed in 21 months, with volume production starting in July 1993.

1992

The PowerPC 603 (which focused on lowering power usage) and 604 (which focused on high performance) projects were also underway at the same time. In July 1992, the decision was made to scale back the ambition of the initial system software release; instead of attempting to create a completely new kernel, Apple focused on producing a version of System 7 where portions of the existing Macintosh Toolbox ROM were rewritten to use native PowerPC code instead of emulating a 680x0.

This provided a significant performance boost for certain highly utilized parts of the operating system, particularly QuickDraw. The first public demonstration of the new Power Macintosh — specifically, a prototype of what would become the Power Macintosh 6100 – was at an Apple Pacific sales meeting in Hawaii in October 1992.

1993

Working with IBM, and making it available to everyone, we can have a much wider impact with these technologies than we did with the Macintosh." Development of the PowerPC 601 chip started in October 1991 and was completed in 21 months, with volume production starting in July 1993.

The first computers to ship with a PowerPC chip were a line of IBM RS/6000 workstations in September 1993.

A fourth project, the Macintosh Processor Upgrade Card, was started in July 1993 with the goal of providing a straightforward upgrade path to owners of Centris- and Quadra-based Macintosh computers.

Over the next five years, Apple replaced all these ports with industry-standard connectors. The first generation of Power Macintoshes had shipped with NuBus, but by the end of 1993 it was becoming clear that Intel's PCI bus was going to be the widely adopted future of internal expansion.

1994

as the core of the Macintosh brand from March 1994 until August 2006. Described by MacWorld as "The most important technical evolution of the Macintosh since the Mac II debuted in 1987", the Power Macintosh is the first computer to use the PowerPC CPU architecture, the flagship product of the AIM alliance.

Computers upgraded in this fashion received new names such as "Power Macintosh Q650" and "Power Macintosh 900". === Release and reception (1994-1995) === The original plan was to release the first Power Macintosh machine on January 24, 1994, exactly ten years after the release of the first Macintosh.

This was reduced to one model in the new product strategy, with the exception of the Power Mac G4 Cube in 2000 and 2001. === 1994-1997 === Apple named Power Macintosh models from this period after the first pre-PowerPC model of Macintosh to use a particular form factor, followed by a slash and the speed of the CPU.

1995

By January 1995, Apple had sold 1 million Power Macintosh systems. 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 first PCI-based system was the range-topping Power Macintosh 9500, introduced in May 1995.

1996

They also noted that the 8500 runs an average of 24 to 44 percent faster than a similarly-clocked Intel Pentium chip, increasing to double on graphics and publishing tasks. The transition to PCI continued into 1996, with the introduction of the all-in-one 5400, desktop 6300/160 (usually sold as a Performa 6360), and mini-tower 6400 models.

1997

In some cases, these companies produced adapters that matched the aesthetic design of the Power Mac. === Industrial design and the Megahertz Myth (1999-2002) === Shortly after Steve Jobs' return to Apple in 1997, Jony Ive was appointed senior vice president of industrial design.

1998

The G5's enclosure design was retained for the Mac Pro and continued to be used for seven more years, making it among the longest-lived designs in Apple's history. == Models == The Power Macintosh models can be broadly classified into two categories, depending on whether they were released before or after Apple introduced its "four quadrant" product strategy in 1998.

1999

When the Power Macintosh G3 (Blue and White) was introduced in early 1999, the port was replaced by two FireWire 400 ports.

The Power Macintosh G3 excluded the AAUI port. The Power Mac G4 (AGP Graphics) was released in the second half of 1999; it was the first Power Macintosh to include only industry-standard internal and external expansion.

The result was the Power Macintosh G3 (Blue and White), a machine that received considerable plaudits from reviewers, including PC Magazine's Technical Excellence Award for 1999.

Before the introduction of the Power Macintosh G3 (Blue and White) in 1999, Apple had shipped Power Macintosh-labelled machines in nine different form factors, some of which were carry-overs from pre-PowerPC product lines, such as the Quadra/Centris 610 and the IIvx.

2000

The introduction of the Blue and White G3 mini-tower also marked the end of the desktop and all-in-one Power Macintosh case designs, the latter being replaced by the iMac. A second model called the Power Mac G4 Cube was introduced in 2000, which fitted the specifications of a mid-range Power Mac G4 into a cube less than 9" in each axis.

This was reduced to one model in the new product strategy, with the exception of the Power Mac G4 Cube in 2000 and 2001. === 1994-1997 === Apple named Power Macintosh models from this period after the first pre-PowerPC model of Macintosh to use a particular form factor, followed by a slash and the speed of the CPU.

2001

This was reduced to one model in the new product strategy, with the exception of the Power Mac G4 Cube in 2000 and 2001. === 1994-1997 === Apple named Power Macintosh models from this period after the first pre-PowerPC model of Macintosh to use a particular form factor, followed by a slash and the speed of the CPU.

2003

And in 2003, Maximum PC ran a variety of gaming, Photoshop and LightWave 3D benchmarks, and reported that the Dual 1.25 GHz G4 system was about half the speed of a dual-processor Intel Xeon Prestonia 2.8 GHz system.

A related criticism leveled at Power Mac systems from this time, particularly the G4 Mirrored Drive Doors, was the increased fan noise level compared to older systems. === The Power Mac G5 and the end of Power (2003-2006) === By the time the Power Mac G5 was unveiled at Apple's Worldwide Developers Conference in July 2003, Apple's desktop range had fallen significantly behind competing computers in performance.

InfoWorld described the G5 as "Apple's best work yet", and said it "delivers on the present need for rapid computing, deep multitasking, and responsive user interfaces — as well as the future need for mainstream computers that rapidly process and analyze massive data sets." PC Magazine again awarded the Power Mac G5 with its Award for Technical Excellence for 2003.

Another claim made by Steve Jobs at the 2003 Worldwide Developers Conference was that the company would be selling a 3 GHz G5 by mid-2004; this never happened. Three generations of Power Mac G5 were released before it was discontinued during the Mac transition to Intel processors.

2005

The Power Mac was discontinued as part of the Mac transition to Intel processors announced in 2005, making way for its replacement, the Mac Pro. == History == === RISC exploration (1988-1990) === The developmental essence of what would become Power Macintosh technology began in mid-1988. Jean-Louis Gassée, president of Apple's product division, started the "Jaguar" project with the goal of creating a computer that would be the fastest desktop computer on the market, capable of voice commands.

The announcement of the transition came in mid-2005, but the third generation of G5 systems was introduced towards the end of 2005.

2006

as the core of the Macintosh brand from March 1994 until August 2006. Described by MacWorld as "The most important technical evolution of the Macintosh since the Mac II debuted in 1987", the Power Macintosh is the first computer to use the PowerPC CPU architecture, the flagship product of the AIM alliance.

It also required an IEC 60320 C19 power connector that was more common on rackmounted server hardware, instead of the industry-standard C13 connector used with personal computers. The official end to the Power Macintosh line came at the 2006 Worldwide Developers Conference, where Phil Schiller introduced its replacement, the Mac Pro.
