iPhone 5 Will Almost Certainly Use Apple A5 Dual-Core Processor

by Reads (8,656)

The iPad 2 is going to run a new dual-core processor from Apple, and strong evidence has emerged that the next-generation iPhone will also use the A5 chip. This should bring significantly faster performance to Apple’s next smartphone.

Developers and hackers digging around in the iOS 4.3 upgrade that was released yesterday believe they have turned up a few facts.  Looking in the tablet version, they have discovered that the processor for the iPad 2 is referred to as the “S5L8940”. Further exploration of the smartphone version of this software also finds references to the “S5L8940”, leading to the conclusion that a future version of the iPhone will use this processor.

Apple A5 ProcessorMore About the Apple A5
The current iPhone 4 uses the Apple A4 processor that runs at 1GHz. The A5 offers two 1GHz cores on a single chip. Software that is written to take advantage of a dual-core processor can run twice as fast on this new chip.

The A5 is made up of a dual-core ARM Cortex-A9 based CPU (central processing unit) and a PowerVR SGX543 GPU (graphics processing unit).

Apple says the GPU in this chip is up to nine times more powerful than the one on the A4. Hyperbole aside, the A5 is definitely capable of providing 1080p HD video out — the iPad 2 is going to offer this feature, and it’s quite likely the iPhone 5 will too.

This processor comes with 512 MB of of low-power DDR2 RAM clocked at 1066 MHz. This is the same amount used in the iPhone 4, but twice as much as in the original iPad.
