iPhone 5′s A6 Processor is a Custom Designed Chip With 1GB of RAM

Apple-A6-feat

At it’s iPhone 5 event Apple boasted that the new iPhone features a new Apple designed A6 chip that performs twice as fast as the previous iPhone’s A5 chip. Other than this Apple didn’t provide any further details about it’s new chip. But thanks to the guys over at AnandTech, who published a detailed analysis of the processor by looking at the markings from the processor chip Apple displayed in it’s keynote slide and gave us the info about the new chip Apple didn’t.

 

According to their findings, the chip is custom designed and Apple didn’t simply licensed the new chip’s design from ARM Cortex chip and modified it but they designed it themselves based on ARMv7 architecture.

 

Apple thankfully didn’t obscure the details of its A6 slide at the launch event, which gave us a Samsung part number: K3PE7E700F-XGC2. Through crafty navigation of Samsung’s product guide, Brian Klug got us the details. The K3P tells us we’re looking at a dual-channel LPDDR2 package with 32-bit channels. The E7E7 gives us the density of each of the two DRAM die (512MB per die, 1GB total). The final two characters in the part number give us the cycle time/data rate, which in this case is 1066MHz.

Although Apple designed the chip itself, it is manufactured by Samsung (Apple’s rival but a faithful parts supplier) and features a 1GB DDR2 RAM that sports 1066MHz memory. The speed of this RAM is 8,528MB/sec that is 33 percent faster than the RAM found on iPhone 4S. But this RAM is significantly slower than iPad 3′s RAM that runs at 12,800MB/sec, but because of iPad’s larger Retina Display screen the difference does not make a difference.

 

Apple claims that the new iPhone 5′s chip performs 40 percent faster than the chip found on Samsung Galaxy S III, this will be confirmed after the iPhone 5 is released to public. These findings by AnandTech only came from knowing the model number from Apple’s slide, we hope to see a more detailed report when the device is actually shipped on September 21.
