Apple Another Apple-to-switch-Macs-to-ARM post. "Apple engineers have grown confident that the chip designs used for its mobile devices will one day be powerful enough to run its desktops and laptops, said three people with knowledge of the work, who asked to remain anonymous because the plans are confidential. Apple began using Intel chips for Macs in 2005." No idea when Apple will make the switch, but they will do it. I'm thinking 5-10 year timeframe.

Considering that Apple was a co-inventor of ARM from the days of Next computer, and that iOS is basically a stripped down version of OSX, it is very likely that Apple has had this in the works for a very long time.

Apple was one of the the first 3 investors in ARM the company along with Acorn and VLIW.

They did not however "invent" the "Acorn RISC Machine" processor. That was done by Acorn on it's own several years earlier.

The real shame is that Acorn didn't hang in there, could have been one of the biggest international companies by now. Their processor legacy is pretty much in every device I own that is not a desktop or laptop.

Why do Apple fanboys always re-write history?!

ARM already existed for several years before Apple invested money on them.

Perhaps he was just mistaking, that doesn't make him an Apple fanboy or a history rewriter. The mistake doesn't really influence his real statement about iOS.

This place is getting as bad as Slashdot with the rabid Apple fanboy animosity (actually it's everywhere): anything questioning or not praising Apple is responded to with vitriol retort -- this coming from a die-hard Mac user from '95-'08.

Hey Apple fanboys, you won! Be happy. Apple is the most valuable company in the world, everyone has (wants) an iPhone, and the iPad has been selling like crazy! No need to be on the defensive about your platform any longer.

I really like this site (a site devoted to OSes) and am glad it exists. Thom does a good job with it too.

Apple was not CO-INVENTOR of ARM !!


anyway, it would be great if someone make deep analyze of using ARM instead of intel ivy bridge.


looking from side, all premises that it could be done are there:

1. Apple control third party developers through AppStore
2. Apple control developing tools (language, framework, compiler...)
3. Apple investing heavy in GPGPU & multiprocessing (OpenCL/GDC...)

my question is:

how much faster could professional application* run on ARM + GPGPU chips (vs intel chips) if you optimize everything (metal, compilers, frameworks)?

*FinalCut, Logic, Aperture, Adobe Suit, Cubase, Cinema 4D...?

Is Apple in position to do this:

- potentially leap frog x86 in terms of performances optimizing everything I already mention (metal, compilers, frameworks...)?

That sounds like making something that's slower go faster than something that goes faster.

Why no optimize for the faster option and make it even faster?

iOS devices can do impressive stuff speed wise, but when it comes to certain desktop applications it's hard to beat raw power.

Still, it would be interesting to see if Apple comes with an ARM Mac and how they'd do it.

I don't understand: even if Apple could get that much of a performance boost by using GPGPU on ARM, couldn't they also get the very same perf boost with GPGPU on x86?

Unless I'm missing something, GPGPU does not sound like a major area of differentiation between x86 and ARM, since GPUs must work similarly on both architectures (there's only so many ways to compute a matrix product in silicon).
