Apple's alleged move to ARM processors is expected to take place "as soon as
possible," likely when 64-bit
variations are available at the end of 2012 or by early 2013, according to
SemiAccurate (via MacRumors.
The site is run by Charlie Demerjian, previous editor of U.K. tabloid The
Inquirer.
Though SemiAccurate is not a frequent source of Apple rumors, the site did
report in July 2009 that Apple
was moving away from Nvidia chipsets at a gradual pace. Currently, Apple's
new MacBook Pros and iMacs
exclusively feature AMD Radeon graphics, or Intel's integrated option.
In addition to laptops, the report said that Apple would "presumably" be
looking to move its desktop Macs
to ARM architecture as well. It characterized the transition to Apple-made
chips for its line of computers as
a "done deal."
"Now you realize why Apple is desperately searching for fab capacity from
Samsung, Global Foundries, and
TSMC," the report said. "Intel doesn't know about this particular change of
heart yet, which is why they are
dropping all the hints about wanting Apple as a foundry customer. Once they
realize Apple will be fabbing
ARM chips at the expense of x86 parts, they may not be so eager to provide
them wafers on advanced
processes."
The rumor comes just days after a report indicated that Intel could be
interested in building mobile chips
for Apple, like the A5 processor found in the iPad 2. Intel currently makes
the CPUs powering Apple's
notebooks and desktops, but Apple has turned to ARM processors for a range
of devices, including its
iPods, Airport base stations, and iOS devices, including the new Apple TV.
Apple even entered the chip designing business starting with the A4
processor that powers the iPhone 4
and first-generation iPad. Apple gained the ability to design its own
systems-on-a-chip through the
acquisition of PA Semi for $278 million in 2008.
Even Microsoft has plans for the ARM architecture in the future, as mobile
devices offer longer battery life
with the low-power chips. The Redmond, Wash., software giant revealed at
this year's Consumer Electronics
Show that the next version of its desktop operating system, Windows 8, will
run on the ARM's architecture.

发帖数: 2283 | 4 I guess the ARM design, i.e. Ax, hasn't been good enough for Apple to do
this move. The performance is not that simply scalable to the number of
cores in the chip. It more makes sense that Apple will employ IBM Cell
architecture for its performance oriented product line in the future.
IBM Cell architecture can also help Apple enter gaming market if it wants. |
