LONDON – The A6 processor inside Apple's iPhone 5 mobile phone is a dual-core Cortex-A15 manufactured for Apple by Samsung Electronics Co. Ltd. in its 32-nm HKMG manufacturing process, according to analysts at Nomura Equity Research.
This would mean Apple is one of the first companies to introduce a Cortex-A15-based processor. Cortex-A15 is the highest performance processor core from intellectual property licensor ARM Holdings plc (Cambridge, England).

Samsung said it had started sampling the industry's first dual-core ARM Cortex-A15 processor late in 2011, the Exynos 5250, made with its 32-nm HKMG process and intended for volume shipment in summer 2012. The Exynos 5250 includes Mali graphics, and is intended for use in high-end tablet computers. Its 2-GHz clock frequency is claimed to double the performance of the previous 1.5-GHz dual-core Cortex-A9 based Exynos.
Apple provided few details when it launched the iPhone 5 on Wednesday (Sept. 12) about the smartphone's application processor and graphics capability. The company did say the A6 processor provided twice the CPU performance and twice the graphics performance of the A5x used in the iPhone 4S.
Nomura provided no source for its report nor a clock frequency for the processor. Typically, mobile phone application processors run with clock signals of up to 1.5 GHz. However, designing in the Cortex-A15 could help explain how Apple has achieved performance equivalentto the iPhone 4S
Apple is expected to retain graphics IP licensor Imagination Technologies Group for the graphics rendering portion of the chip. The Apple A5 processor is reported to use the dual-core PowerVR SGX543MP2, so the A6 could use the quad-core version, the PowerVR SGX543MP4.
Taiwan Semiconductor Manufacturing Co. (Hsinchu, Taiwan) was reportedly working on a version of the A6 processor for Apple in 2011. It was rumored then to be a quad-core design for implementation in 28-nm manufacturing process and was expected to debut in the third-generation iPad.
If Samsung is the sole supplier of the A6 processor – as indicated by Nomura analysts – this squares with recent predictions that TSMC is working on pulling in its 20-nm process and working to supply Apple in the second-half of 2013 using that process.
"the use of Cortex-A15 could help explain how Apple has achieved the equivalent talk time to the previous iPhone 4S" - no it couldn't. The die shrink from 45nm to 32nm would explain that.
Why does EETimes keep publishing baseless speculation from unqualified analysts? The analysts in that iphone 5 predictions article yesterday got 2 out of 9 predictions correct.
there is a pro-ARM ( pro Brit ) agenda being pushed here by the reporter based in Londonistan at the expense of giving US readers of EE Times a well-informed or balanced perspective. Thx to EE Times employment policies we will just have to do it ourselves.
Yeah sure, an article to maintain the hype around an extortionately large American fashion brand, crApple, has an anti-American bias :/
As for ARM, they offer more competition in the marketplace by licensing their IP to third parties. Anyone with any wit would support the ARM model over Intel's -- just compare the prices of ARM silicon to Intel's -- an order of magnitude cheaper. Puts all Intel's extortionate profits into perspective when compared to the slim earnings of ARM.
This should be an interesting mix of processing power vs battery life. If the performance has been jacked up to 2x as they claim then assuming it consumes the same power as it's predecessor it should still result in longer battery life and faster response times.
So I guess the quad core version of it will go into next Ipad.
If you can believe Apple's website, there's 225 hrs vs 200 on standby, 8 vs 6 hrs browsing on 3G and 10 vs 9 hours while browsing on on WiFi. Talk time is 8 hours for both. This is 5 vs 4GS BTW. They seem to have used the most of the extra speed/power trade off for speed if the 2x speed improvement holds water
And dont forget there is the chance to upgrade with a couple of Cortex-A7 cores tucked in to a corner of a dual-core Cortex-A15 processor design.
That would create a quad-core processor that implements the "big-little" power-saving technique.
Such chips are expected to arrive and be powering smartphones in 2013 as I remember Warren East saying at the launch of Cortex-A7 in 2011.
Well in my opinion it is too early to see an A15-based SoC powering such an important and high volume product as the iPhone.
The 2x claim by Apple is quite unsubstantial and not based on a specific metric (e.g. a benchmark). Therefore compared to the A5 processor in iPhone 4S, my best guesses are that this "2x claim" could come from the following:
- using 32nm process instead of 45nm could lead to an increase from 1GHz dual A9 to 1.5 GHz (maybe more?) again dual A9
- certain tweaks here and there
- beefier memory subsystem (maybe another memory controller or higher frequency DRAM?)
- beefier graphics
- software improvements.
I don't know whether to get an Apple iPhone5 or a Samsung Galaxy3 ? Apple could go under without Steve Jobs and the patent infringement lawsuit Apple won against Samsung could be a desperate attempt to survive, won't Samsung just charge whatever they need for the A6 to recoupe the Apple win ? Or make the A6 "short of supply" to Apple , I might not want to be on the wait list for the iphone 5 in that case... Apple and Samsung don't seem to be playing well together... or maybe that's just how they play... but currently... it sounds like there is no iPhone 5 with out Samsung A6, and there is no Samsung galaxy3 if Apple shuts down their production through litigation...
Apple has hundreds of billion dollars in retained earnings, and a multi-billion dollar annual revenue stream. The company took in $46 billion in Q4 2011. Tim Cook is doing a great job as CEO, and new products keep coming.
I suspect Apple has thought of the vulnerability to Samsung, and has a second source for the Cortex-based A6.
Jobs was smart and visionary, but there are plenty of people with those characteristics still at Apple.
So no, I don't think Apple is going under anytime soon.
Samsung is a multinational gaint with deep pockets and smart people, so I think they'll find a way to produce the Galaxy 3.
So your choice should be more about the user experience you want. I'd go to a store and try out both phones, or check out friends' phones.
You can't be serious! Get whichever phone you think you will like best. Neither company is going anywhere any time soon. Even while they fight in court, they are enjoying a mutually beneficial symbiosis.
Apple-Samsung sort of reminds me of the U.S.-China relationship -- "frenemies" that can't live without each other even though at times they get really ticked off at each other.
Samsung will never jeopardise processor sales with Apple because of what happens in the courtroom, it would destroy their ability to sell to anyone of any size. And anyway, it seems the publicity for Samsung out of the lawsuit was actually worth it weight in gold.
Anandtech is now claiming its an Apple custom ARM 7vs implementation similar to Krait from Qualcomm.
Has VFP4.0 but isn't an A15.
xcode shows armv7 and armv7s as architectures
I think any talk of Apple or Samsung going under is silly, Samsung has finally figured out how to make a smart phone, as have many others and Apple is going to see their margins go down lest they lose market share (not just to Samsung) When the iPhone came out it was truly revolutionary, but now very little separates it from the others. The only thing they do better really is marketing, ie. making a lot of people think they are worth the premium.
BTW, a 16GB iPhone 5 costs AUD$799 in Australia, we must be pretty gullible.
