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.

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.
Apple's decision to ditch PowerPC brought it closer in line with Windows OEMs, who also use Intel chips. [Image Source: Bryon Realey/Flickr]
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.

Lol, MS did the exact same thing as a test by developing Win RT and experiementing with the desktop interface on it.
At first they thought simply recompiling for ARM would be great. They sure found out its not quite as simple as that though.
I applaud Apple for trying, but mostly because they are playing catchup on something thats already been tried and doesn't really work (for the purpose of replacing x86-64).
Very un-Apple. Good luck with that.

The problem is that (excluding .net apps) every 3rd party developer would also have to recompile for ARM as well (to include every 3rd party binary library they used); without that happening you'd have no clear way for consumers to know what apps would/not work on WOA. The result of that would (like every other compatibility issue windows has ever had) be blamed entirely on MS and be used to argue the Win8 was crap. Drawing a strict line in the sand is much safer.
Unless ARM gets to the point of being able to emulate x86 at near atom performance levels it's not going to happen.
