5525-410: The first personal computer to feature a 64-bit processor. He promised a 3 GHz Power Mac G5 within 12 months, but never released such a product. In 2004's WWDC keynote address, Jobs addressed the broken promise, saying IBM had trouble moving to a fabrication process lower than the 90 nm process . Apple officials also said in 2003 they planned to release a PowerBook with a G5 processor, but such

5610-601: The fourth generation iPad Pro , which was announced on March 18, 2020. It adds an additional GPU core, compared to the A12X, for improved graphics performance. The A12Z is also used in the Developer Transition Kit prototype computer that helps developers prepare their software for Macs based on Apple silicon. The Apple A13 Bionic is a 64-bit ARM-based SoC that first appeared in the iPhone 11 , 11 Pro , and 11 Pro Max , which were introduced on September 10, 2019. It

5695-452: The impression that they could use the DTK for a full year, being caught in surprise by Apple's email indicating that they soon had to return the DTK. Many were also indicating that they were unhappy about the US$ 200 discount code offered by Apple, comparing it to when Apple unexpectedly offered developers the option to return their Intel DTK earlier than the originally planned date for an iMac during

5780-580: The last models to switch, with the Mac Pro available immediately and the Intel Xserve available by October, although shipments for the latter computer line did not start until December. The final version of Mac OS X that ran on PowerPC processors was Leopard , released in October 2007, with PowerPC binary translation support (using Rosetta ) persisting up through the following version, Snow Leopard . Support

5865-595: The launch of the iPad Air 2 on October 16, 2014. It is a high performance variant of the Apple A8 . Apple states that it has 40% more CPU performance and 2.5 times the graphics performance of its predecessor, the Apple A7 . Unlike the A8, this SoC uses a triple-core CPU , a new octa-core GPU , dual channel memory and slightly higher 1.5 GHz CPU clock rate. It uses an integrated custom octa-core PowerVR GXA6850 graphics processing unit (GPU) running at 450 MHz and

5950-405: The move risks diluting Apple's value proposition, since it will now have less control over its product road map, in addition to the risk of alienating its loyal users. Some observers expressed surprise that Apple made a deal with Intel instead of with AMD . By 2005, AMD had become popular with gamers and the budget conscious, but some analysts believed AMD's lack of low-power designs at the time

6035-452: The power compared to its predecessor, the Apple A7 . On February 9, 2018, Apple released the HomePod, which is powered by an Apple A8 with 1 GB of RAM. The A8 features an Apple-designed 1.4  GHz 64-bit ARMv8 -A dual-core CPU, and an integrated custom PowerVR GX6450 GPU in a four cluster configuration. The GPU features custom shader cores and compiler. The A8 is manufactured on

6120-436: The program would run for the duration of one year counted from the moment the developer signed up for it, with an option to terminate it early without reason. Additionally, it had a specific provision regarding one of the benefits associated with the program, namely the DTK. The DTK was to be returned within 30 days after the end of the program itself or "as otherwise earlier requested by Apple". Apple had earlier communicated that

6205-538: The release of 10.7 Lion , which was released in July 2011, five years after the transition was complete. The last Apple application to support PowerPC processors was iTunes 10.6.3, which was released on June 11, 2012. Apple has a policy of placing products that have not been sold for more than five years, but less than seven years, as "vintage", meaning hardware services from Apple Stores and service providers are subject to availability of inventory, or as required by law. After

6290-403: The transition from PowerPC to Intel processors . During the last transition, a developer could also choose to keep the DTK for the whole length of the program except that they would not get the iMac. On February 5, 2021, following developer backlash, Apple sent out another email that increased the discount code to US$ 500 and expanded the discount to be used on any other Apple devices. In addition,

6375-462: The user wanted to use Mac OS. In the years since the end of the Star Trek project, there were reports of Apple working to port its operating system to Intel's x86 processors, with one engineer managing to get Apple's OS to run on a number of Intel-powered computers. In 2001, Jobs and then Sony president Kunitake Andō reportedly had a meeting to discuss the possibility of running Apple's operating system on its Vaio computers. Jobs even presented

6460-544: Was announced, it was noted that the translation software is designed to translate applications that run on a "PowerPC with a G3 processor and that are built for Mac OS X." It was noted at the time that translated software performs at a level between 50% and 80% of native software. The announcement caused concerns over performance. At the time the transition was announced, it was noted that a degree of enmity towards Intel exists amongst some fans of Apple products, due to Intel's close identification with Microsoft. In addition, It

6545-626: Was behind Apple's decision to go with Intel. In 2011, Apple investigated using AMD's low power Llano APU for the MacBook Air , but eventually opted for Intel due to AMD's potential inability to supply enough Llano processors to meet demand. Apple had created the world's first consumer 64-bit desktop computer with its G5 based line-up; however, the first Intel-based Macs included only Intel Core Duo processors, which were 32-bit. Apple refreshed its line of computers six months later, adding Intel's new Intel Core 2 Duo 64-bit processors. When Rosetta

6630-510: Was floated after Jobs departed but was quickly disapproved by management. The first known attempt by Apple to move to Intel's platform was the Star Trek project , a code name given to a secret project to run a port of Classic Mac OS System 7 and its applications on an Intel-compatible personal computer. The effort began on February 14, 1992, with the blessing of Intel's then-CEO Andy Grove . Apple leaders set an October 31 deadline to create

6715-445: Was later dropped in Lion . In 2020, Apple announced that it would shift its Mac line to Apple silicon , which are ARM -based processors developed in-house. Apple had been using PowerPC processors in its products for 11 years when the move to Intel processors was announced. At 2003's WWDC keynote address, Jobs unveiled a Power Mac with a processor from IBM's PowerPC G5 product line,

6800-435: Was later used in the iPhone 4 smartphone, the fourth-generation iPod Touch , and the 2nd-generation Apple TV . The Cortex-A8 core used in the A4, dubbed " Hummingbird ", is thought to use performance improvements developed by Samsung in collaboration with chip designer Intrinsity , which was subsequently acquired by Apple It can run at far higher clock rates than other Cortex-A8 designs yet remains fully compatible with

6885-501: Was not included. It eventually appeared in the first three models of Apple silicon Macs, operating in Thunderbolt 3/ USB4 mode. The DTK came preloaded with beta versions of macOS 11 Big Sur . The A12Z DTK would be directly succeeded by the 2020 Mac mini with the M1 chip. In an interview shortly after the introduction of the DTK, Apple’s SVP of Software Engineering Craig Federighi praised

6970-475: Was noted by Intel's then CEO, Paul Otellini , that Apple and Intel's relationship was strained at times, especially due to Apple's commission of an ad that shows Intel processors being outperformed by PowerPC processors. While there were questions over whether Apple would put the Intel Inside stickers on its products, Jobs dispelled such a possibility, saying it is redundant when Apple's use of Intel processors

7055-414: Was noted that there was a debate over the difference of endianness between Intel and non-Intel processors, as well as the merits of each CPU architecture. The difference in endianness meant that some software could not simply be recompiled; it required changes to make it work on processors of either endianness. During Apple's 2005 WWDC , the company introduced a Developer Transition Kit consisting of

7140-613: Was the second time Apple had switched the processor instruction set architecture of its personal computers. The first was in 1994, when Apple discarded the Mac's original Motorola 68000 series architecture in favor of the then-new PowerPC platform. Apple's initial press release originally outlined that the move would begin by June 2006, with completion slated by early 2008 - the transition had proceeded faster than anticipated. The first-generation Intel-based Macs were released in January 2006 with Mac OS X 10.4.4 Tiger . In August, Jobs announced

7225-456: Was touted by Apple as a completion of its transition to Intel, and said the entire process took 210 days. Mac OS X Snow Leopard (10.6) , released in August 2009, was the first version of Mac OS X (later macOS ) to require a Mac with an Intel processor, ending operating system support for PowerPC Macs three years after the transition was complete. Support for Rosetta was removed from Mac OS X with
