The iPhone 5 Could Be The First Phone To Utilize ARM Cortex A15 Cores [Report]


As usual, Apple has kept quiet about the internals of the iPhone 5. We know that Apple has upgraded to an A6 processor, yet we aren’t even sure if it’s a dual-core or quad-core yet. To shed some light onto the situation, AnandTech speculates the A6 performance gains are due to ARM Cortex A15 cores:

Based on the performance gains, Apple’s history of SoC naming and some other stuff we’ve heard recently, it looks like Apple has integrated two ARM Cortex A15 cores on Samsung’s 32nm LP HK+MG process. This is a huge deal because it means Apple beat both TI and Samsung on bringing A15s to market.

As this is just speculation currently, we will have to wait until iFixit completes their annual iPhone teardown to see what the iPhone 5 beholds. While we wait, you could begin thinking about the GPU. Apple mentioned that it was 2X faster than the iPhone 4S, so once again, AnandTech has more:

The GPU side isn’t entirely clear at this point, but the 2x gains could be had through a move to 4 PowerVR SGX543 cores up from 2 in the iPhone 4S.

If the iPhone 5 indeed utilizes ARM Cortex A15 cores, then the A6 is simply an enhanced dual-core processor. But it won’t be long until September 21st hits and we learn the official truth.

    I hate to say it, but its gonna be a dual core. If it was quad core apple would have stamped a shiny quad core sticker right the iphone 5 page. I really wanted it to be quad core but id say our chances are less than 1%.

    My gut feeling says the same. Seems weird that Apple ended their pattern, A4 single, A5 dual, would of thought A6 would be quad. Guess it would have to end sometime though, there really isn’t a need for quad-core phones right now. Dual-core phones get the job done fast.

    If the A6 is based on A15 architecture then it should be more powerful than any quad cores on the market, as well as more power efficient. A15 architecture would essentially ‘future proof’ the iphone for another year or two.
