Intel roadmap 2013 mac pro
The transition marked the Macintosh platform's second migration to a new CPU architecture. The first was the switch from the Motorola "68k" series architecture used since the original Macintosh K to the PowerPC architecture.
Get Ready For Big Changes to Apple's Mac Lineup - The Mac Observer
Apple's initial press release indicated the transition would begin by June , and finish by the end of , but it actually proceeded much more quickly. Apple released Mac OS X v The names of some of Apple's desktop and laptop product lines changed between the PowerPC version and the corresponding Intel version. Most notably, the word "Power" was dropped from all product lines. During the Keynote address at Macworld in , where the first Intel-based Macs, the iMac and MacBook Pro, were announced, Steve Jobs remarked that the new naming schemes for their products reflected their desire to have "Mac" in the name of all of their computers, and because they were "done with power.
The first known attempt to move to Intel platforms was the Star Trek project from spring to , a joint effort with Novell to port Mac OS 7 to run on ordinary PCs. The ported System 7. While the project was successful with running pre-beta versions it was stopped in after management and strategy changes.
This took several years, during which Apple produced versions of the classic Mac OS that could run on either platform, introduced fairly low-level emulation of the 68k architecture by the PowerPC models, and encouraged third-party developers to release fat binaries that could run natively on either architecture. This transition also took a number of years, and was facilitated by the inclusion of Classic , an environment in which an instance of Mac OS 9 could be run, permitting the execution of programs that had not been ported to Mac OS X, as well as the introduction of Carbon for Mac OS 9 and Mac OS X, allowing programs to run natively on either system.
It is not publicly known whether Apple maintains current builds for any other architectures although the related iOS runs on the iPhone 's ARM architecture.
Steve Jobs stated that Apple's primary motivation for the transition was their disappointment with the progress of IBM's development of PowerPC technology, and their greater faith in Intel to meet Apple's needs. In particular, he cited the performance per watt projections in the roadmap provided by Intel.
Further, the heat produced by the chip proved an obstacle to deploying it in a laptop computer, which had become the fastest growing segment of the personal computer industry. Some observers were surprised that Apple had not made a deal with AMD , which had in recent years become a strong competitor to Intel. AMD had recently released its competitive bit Opteron platform,   and by moving straight to x Apple would have had one less architecture transition.
Analysts have speculated that AMD's lack of low-power designs at the time were behind the decision to go with Intel. Such software could now enjoy much more success with near-native performance through virtualization , such as is currently being done by Parallels Desktop for Mac and VMware Fusion.
For those customers wishing to achieve a more conventional environment, a dual boot solution is possible on an x86 Apple device using Boot Camp software which includes Windows drivers for Mac hardware. Some third-party partitioning options can even provide triple, or even quadruple boot. The performance of Intel's chipsets was a concern, along with the x86 architecture itself, and whether it would affect system performance and application quality.
Other problems include endianness and reduced floating point performance in real world applications relative to equivalent or contemporary PowerPC processors. There was concern that the early announcement of the change would cause an Osborne effect , and there was the possibility that Intel could force Apple to use the Intel Inside branding.
In addition, Apple had nurtured a feeling of animosity toward Intel among its loyal base.
The Macintel Report
It would take time and money to convince Apple's most loyal customers that Intel was acceptable. There were also fears that Intel, which took part in the development and implementation of the USB , would force Apple to drop all development and support of its FireWire serial bus on all Intel Macs. This did not occur, as FireWire ports continued to be included on all Macs, except certain notebook configurations beginning with the MacBook Air in , until being replaced by the faster Thunderbolt port.
Many of these fears were put to rest at Macworld with the arrival of the first Intel-based Macs. Rosetta was improved to offer much faster speeds than originally demonstrated though benchmarks suggest that PowerPC code still does not perform as well under emulation on a Core Duo iMac as it does on a G5 iMac .

Fears of an Osborne effect were dismissed after sales of Macs for the Christmas quarter saw an increase over the previous Christmas. There were questions over the extent to which Apple would retain control over the non-processor components of the system design. Apple is traditionally a systems builder, and some feared that Apple's industrial design philosophy may be affected if the company switched to commodity parts. Others noted that Apple has slowly been switching to standard parts since the introduction of the PCI Power Mac in , and said that using a non-Apple chipset in itself would not harm the Mac's image.
The use of the x86 architecture allows Windows to run natively on Apple hardware, and opens the possibility of using the Wine package to run Windows executables directly. Some [ who? Others say that it could be a boon to switchers , since they would not have to leave their Windows applications behind while trying out Mac OS X. Intel was seen among the Mac community as a purveyor of hot-running chips especially the Pentium 4.
Apple themselves mocked the Pentium range in their "Toasted Bunnies " advertisements of the late s. However, the Pentium M chips, which were designed for laptop use, run much cooler than the Pentium 4. Apple claimed the then-new Intel Core chips, which are based on the Pentium M microarchitecture, would have dramatically better performance per watt than the PowerPC G4 and G5. That email "quote" was floating about everywhere last night - including here.
I wouldn't read too much into it. And to many it is. I can easily see a very high end iMac that replaces the MacPro but I have a very hard time believing that a traditional PC Box version of the MacPro is in the works anywhere. Franz: "Our pro customers are really important to us Could apply to a rack-mountable server for example as well as a rethought tower.
Another year of angst? Comments generally are not sympathetic to waiting again for Apple to show you more love! I just replied in another thread that it should be acknowledged the procession of the switch to intel which first occurred in the laptop line and then rolled out to the imac and macpro. The retina display is what will really drive an imac or macpro upgrade. Ask yourself; does it make sense to upgrade a product line now if your goal is to have thunderbolt retina displays and retina imacs in the next 6 mos or more?
Did the G5 get any significant upgrade after the intel macbook release? When you look at the macpro bump in that light, I think you can feel confident that there is indeed something big on the horizon. Otherwise, why bother? Keith Koby Sr.

Pretty significant upgrade if you ask me. But then was not the same as now. The Mac Pro was released about a month after the Xeons that powered it were. There is a newer Intel architecture available today Sandy Bridge E5 Xeons , but Apple, for the first time, has released a "new" Mac Pro that doesn't use Intel's latest and greatest.
Others are not so good. Much has been made of David Pogue's quote: "Many Apple observers also wonder if Apple thinks that desktop computers are dead, since not a word was said about the iMac and Mac Pro.

An executive did assure me, however, that new models and new designs are under way, probably for release in All this quote says to me as that Apple will have new desktops sometime between 6 months and 18 months from now. Apple's desktops are all a year or two behind. This is the second time in year that Apple has left a gigantic hole in their professional video offering. That is a great fit for some, but it's not a compelling offering across the entire platform like they used to offer. To allow unimpeded reworking of the 'workstation' meme - multiple retina TB displays Whatever it is I reckon it was there sitting in Jony's design studio for Steve to drop in and admire since Intel got the Light Peak demo show on the road with some OS X guts.
But Tim Cook can't actually get a functioning supply train in operation - yet. As to Pogue, in respect to the iMac I think his Apple Executive's quote could have been referring to the full make-over next generation iMac with Haswell guts - which I understand will have vastly improved integrated graphics power. Seems it will still be DP1.
