However, rumors that Apple will soon switch its Macs to ARM-based CPUs are buzzing. Apple, Inc.īack in the present day, Apple’s Intel-based Macs sell well and likely have a solid CPU roadmap ahead of them. The final Intel Mac model is yet to be determined, but if you believe some pundits, it might arrive later this year.

Rosetta was eventually removed from Mac OS X starting with Mac OS X 10.7 Lion.ĭepending on how you count, since 2006, Apple has released at least 80 models (perhaps as many as 100) of Macs with Intel CPUs. Shortly after, developers began to distribute their programs as universal binaries, which could run on either PowerPC or Intel Macs, which greatly eased the transition to x86.

It could dynamically translate some PowerPC code to Intel on the fly.

To preserve software compatibility between generations, Apple included an advanced emulation technology called Rosetta starting with Mac OS X 10.4.4. The first Intel Mac models were announced in early 2006: an iMac and the MacBook Pro. Mac CPU performance increased almost four-fold overnight. After years of advertising that touted the superiority of PowerPC over Intel, Apple switching to Intel felt like a lifeline for Macintosh. So, when Apple announced it would transition to Intel chips at WWDC 2005, critics were happy, but surprised. Also, by the G5 generation, PowerPC chips were so power-hungry, they required extensive cooling to operate, precluding their use in laptops. Macs had trouble keeping speed parity with Intel-based PCs due to the delays in the production and design of new PowerPC chips. Apple, Inc.īy the mid-2000s, Apple felt hamstrung by its reliance on PowerPC CPUs. Intel x86 (2006-Present) The first iMac to use an Intel processor (2006). The final Apple PowerPC model was an iteration of the Power Mac G5, released in November 2005. PowerPC CPU clock speeds increased dramatically during this era, ranging from 60 MHz all the way up to 2.7 GHz. Over the years, Apple released around 87 different Mac models that used PowerPC CPUs, including chips in the 601, 603, G3, G4, and G5 series. This meant these new Macs could run almost all older 68 K software seamlessly (albeit with some speed penalties), allowing a smooth transition to PowerPC. Apple designed a 68 K emulator that was included with every copy of Mac OS.

It was first used in a series of workstations from IBM, and then in 1994 in the Power Macintosh 6100. The three companies wanted to use this to fend off the Microsoft-Intel domination (also known as “ Wintel“). Apple explored many different RISC CPU options, but eventually partnered with IBM and Motorola to design a common CPU platform. This design technique promised faster CPUs. In the late 1980s, the computing industry began to turn away from the legacy 1970’s CPU architectures in favor of new trends, like Reduced Instruction Set Computing (RISC). PowerPC (1994-2005) The Apple Power Macintosh 6100, the first PowerPC-based Mac. The final Mac model to do so was the PowerBook 190 in 1995. Overall, at least 72 different Macs used 68k CPUs. These increased in speed and complexity over time. Over the next decade, new models of Macintosh computers began using successors of the 68000, including the pure 32-bit 68020, 68030, and 68040 chips. This delighted Steve Jobs, who wanted to upstage the Lisa team. The Apple Lisa used only a 0, but the new Mac prototype could run at 8 MHz. However, after a designer saw the a mazing graphics routines that were being created for the 68000-based Apple Lisa, the more expensive 16/32-bit 68000 was used. While in development, an early Mac prototype used an 8/16-bit Motorola 6809 CPU. In 1984, Apple released the first Macintosh computer (called, unsurprisingly, the Apple Macintosh). Motorola 68 K (1984-1995) The Apple Macintosh (1984) was the first Mac to use a Motorola 68k CPU.
