Report: A6 chip in Apple iPhone 5 is a custom design; 1GB of RAM is aboard
While Apple didn't delve too much into the A6 SoC inside the Apple iPhone 5 when it introduced the phone last week. Apple did discuss certain performance benchmarks, Still, Anandtech was able to look inside the phone and find out some of the things about the device that you were wondering about. First of all, we know that both the Apple iPhone 4 and the Apple iPhone 4S each had 512MB of RAM. Did Apple crank it up to the 2GB seen on the Samsung Galaxy S III? No. The Apple iPhone 5 has 1GB of RAM on board. Still you can't compare the amount of RAM on the Apple iPhone with the amount on an Android model. Because of iOS, the tech titan has always been able to get better performance from a lower amount of RAM than an Android phone can. DRAM weighs in at 1066MHz and at 8,528MB/sec, the memory is 33% above the 6,400MB/sec on the Apple iPhone 4S.

Perhaps the most important news is that Apple has designed much of the processor in-house. Anandtech says that it has confirmed that the A6 is "based on Apple's own ARM based CPU core and not the Cortex A15," and was manufactured using the 32nm process. Designing the A6 in-house means that Apple most likely optimized the design to allow the phone to run at the specific speed it needs for the best customer experience.  The site also says that they believe that the new version of Apple's smartphone is being powered by a dual-core processor. All of those out there who were looking for Apple to go quad-core on the iPhone will have to wait until next year.

I would not brag eith Samsuck. It is just a thief. A cheap copycat who would still making ugly plastic bricks with Bada in it, without Nokia and Apple. Samsung "Inspired by other OEM's"

Home of android users? More like Apple biased website. Hyping up a dual core, 1gb phone that is finally getting LTE is too much. I come here for news updates from many phones not just one.

There's more apple bias overall in the tech site area. Hell, PhoneArena was quite biased towards Apple not that long ago. It was relatively recently that more people are calling Apple and their devout fans on their BS.

I am a Android user and I respect Apple's hardware but you have to admit that the A6 chip set is top tier at this point.

I think this is more a long the "truth line". More people here actually do research on all different type of phones and not just rely on what Apple says.

Just because PA posts an article about Apple's new chip, you accuse them of being biased? Come on. I am not an Apple fanboy. I personally am curious about what is powering the iP5. I suspect there are one or more readers out there who share my interest.

I share :D At least we finally know that a6 chips is not quad core... take that Apple!! For make those marketing gimmick to brainwash fanboy

Wendy some days you say good things about iPhone, some days you trash them... Dont let yourself get swayed by what others say. Dont be a fan, be yourself... all the time. I like the apple avatar you had before. Especially since the person in the pic is not you.

Here on PA everything is biased if non-android related. The site is infested with fandroids....

"Here on PA everything is biased if non-android related." You must be a recent join. There are quite a few Apple fans as well. Even some WP and BB/RIM fans too.

I'm a WP fan but I also like Android. In fact, I had 2 Android phones but last December 2011, I converted one phone to WP7 and loved it. So now my primary phone is WP and my secondary is Android. Unfortunately this December, both my phones will be WP8 but I don't hate Android. As to Apple, I like Apple products too except the iPad. Unfortunately I did not like Steve Jobs so that is what's keeping me from fully using the iPhone. Sorry.

I'm not sorry I'm going to buy 2 WP8 phones. I'm sad actually to leave Android. But can't help crossing over completely to WP8... really, really love the OS.

I have the same dilemma. I absolutely love WP8, but I absolutely love Android too... D:

what are you talking about? I own a windows 7.5 phone as well as android devices. I was making fun of the way the statement was typed, not the device.

Almost any site that is not like cult of mac or something will have more android supporters. Gennerally android users are more likely to understand tech, so you will find them on thec sites more. However w "fandroids" are not always ignorant and biased. I remember in an article where samsung was accused of child labor, Taco, (if you don't know him he was the leader of this sites isheep and was constantly los ing arguments with us "fandroids) said something like that samsung is just as bad as apple and got almost 20 thumbs up and only a couple thumbs down. There have been other scenarios that I don't remember right now where people supporting apple got a lot of thumbs up. We do not just randomly thumb people down, we thumb you down if you say Iphone 5 is better than s3 and have absolutely no real argument to support that. If you have a good reason to say that however, we will thumbs you up, no matter who you are.

Oh yeah perfectly share your view here. And finally we all know that the processor in iPhone 5 is dual-core and a cross between the A9 and A15 architectures like the S4. The 1GB RAM is a welcome addition. I'd have got this one if it wasn't the 920 or S3.

ok, where are you gleaming this info. The S6 chip is an A9 dual core 32nm HKG+ manufactured chip. In other words it is a modified Exynos 4212. Its not some "hybrid" of anything. And neither is the S4 Krait chip either. The Krait is a custom design that is neither a true A9 nor A15. However, it is an A9 in performance. Everything else is just salesmen trying to convince you its something better.

The S4 chip is a cross between the A9 and A15 architecture. The S4 is better than A9s but will be no match for true A15s when it arrives to the market.

how? it actually is not nearly as apple-pro as other articles… they did not even call this new chip structure innovation.. they did not say how this chip structure has probably been in the works for a while due to apple's acquisitions a few years back… they did not discuss how the A15 is based for servers and if htc/samsung/lg uses it, it will not function as well as this chip which is specially designed for a mobile os… its called news… and this was certainly not pro-apple
