Report: Apple Looks to Ditch Intel Chips in Macs for ARM

Apple may co-design special new ARM chips for its laptop and desktop computers
Bob Mansfield, Apple, Inc.'s (
"Technologies" group senior vice president
, recently announced that his semiconductor teams have "ambitious plans for the future."
I. Change Ahead?
For Apple, who has been quietly been growing its chipmaking army with acquisitions like
, that could mean a switch from Intel Corp.'s (
) x86 chips on the Mac computer front to
in-house system-on-a-chip (SoC) designs
utilizing ARM Holdings plc.'s (
) proprietary architecture, which is currently found in Apple's iPhones, iPods, and iPads.
suggests Apple is exploring a possible exit from its dependence on Intel chips, over the next several years. The news agency writes:
While Apple is now committed to Intel in computers and is unlikely to switch in the next few years, some engineers say a shift to its own designs is inevitable as the features of mobile devices and PCs become more similar, two people said.
As handheld devices increasingly function like PCs, the engineers working on this project within Apple envision machines that use a common chip design. If Apple Chief Executive Officer Tim Cook wants to offer the consumer of 2017 and beyond a seamless experience on laptops, phones, tablets and televisions, it will be easier to build if all the devices have a consistent underlying chip architecture, according to one of the people.
Apple is rumored to be contemplating switching its Macs to ARM chips.

None of the companies involved were willing to comment on the rumor. However, this has not been the first time that Apple has been rumored to be working on computer-side CPUs in-house.
ARM shares climbed 4.2 percent on the London Stock Exchange following this news, and news that ARM had paid MIPS Technologies, Inc. (
) a lump sum of $350M USD to license its portfolio of 580 hardware patents. The MIPS deal lays to rest concerns that the
rival reduced-instruction set computer (RISC) architecture designer
might be preparing to sue its more prolific peer (ARM).
II. Lesson From the PowerPC Era
Apple may be reticent to jump into a computer-side deployment of ARM too soon.
Only a decade ago Apple was supporting another non-x86 architecture -- PowerPC -- whose chips were co-designed by Motorola and International Business Machines, Inc. (
PowerPC Macs seemed to be faster
in some benchmarks than their higher-clocked Windows/x86 counterparts, Intel's flashy clock speeds during the height of the Megahertz wars hurt Apple from an image standpoint. And Motorola's decision to bail on PowerPC drove Apple to in 2005
finalize its long-standing plans to jump ship
to Intel's x86 chips.
ARM is hardly analogous to PowerPC at present, but it's easy to see why Apple might be uneager to move too fast, should market conditions change. Indeed, the next few years in the chip market are a time of great uncertainty.

On the one hand, Intel is pushing hard to leverage its process advantages to deliver fast, power-efficient mobile cores, cutting into ARM's core business. On the other hand, ARM is invading the personal computer market with
, and is expected to land in the server market
around 2014 with Window Server 2012 R2
. ARM has been boosted by x86 veteran Advanced Micro Devices, Inc.'s (
) decision to at least
partially transition its CPU line
to ARM chips.
's sources are accurate, Apple will likely be hard at work designing a possible ARM-based SoC replacement to drop into its MacBook Airs and MacBook Pros. But the decision to pull the trigger may ultimately rest on where ARM stands versus Intel/x86 come 2016-2017.

There is one additional group among whom Macs are very popular -- scientists, particularly physicists and chemists. [This, incidentally, counters the frequently-repeated myth that people just buy Macs for style. Hell, we generally don't care about style -- just look at how we dress!]
Based on my own experience, I think there are four key reasons for the popularity of Macs among scientists: (1) OSX offers a native Unix environment for development work; (2) OSX is significantly more powerful than Windows for very complex office productivity tasks (say, where you have ten programs open, with ten windows in each one, and need to navigate rapidly among them -- I find this easy on a Mac, and hopeless in Windows); (3) broadly speaking, OSX offers a more intuitive interface--for scientists, our computer is just a tool, and whatever enables us to most easily and quickly get the job done is what is preferred (our work is challenging enough; we don't need the software to provide additional challenge); and (4) historically, much less bother about security -- with responsible use of either a Mac or a PC you're not going to get a virus; but responsible use of a PC has generally required installation and background operation of antivirus software which (at least in the past) has been a PITA, while responsible use of a Mac has not.
From the above, it should be clear that scientists do a lot of content creation on their computers. Given this, I share the concern that Apple seems to be moving away from content creation and towards content consumption, since I think the former has been its great strength.
