The truth about the interiors of the iPhone 5

The truth about the interiors of the iPhone 5

When it was launched the iPhone 5 , said little or nothing about your CPU and overall hardware you have. Just heard that the performance is “two times better than its predecessor” with endless promises that sought to convince the customer to buy this mobile core processor Apple a6 which no frills.

Sure, we speculate about it, and although it was confirmed that the dual-core CPU , the chip was not based on Cortex-A15 as was believed, nor on ARM Cortex-A9, but a bespoke design by Apple based on the architecture, it gives life to the Cortex-A, but surely strongly modified by the work of Apple and PA Semi, a company dedicated to the design of semiconductors that the bitten apple acquired four years ago .

And is that the phone and fell completely disarmed him curious, so has revealed almost all the details of your hardware:

  • dual core CPU based on ARMv7 architecture, tailored for Apple. Just beyond 1GHz frequency.
  • 1GB DDR2 SDRAM memory LP, manufactured by Elpida.
  • Brand NAND flash memory for mass storage H2JTDG2MBR.
  • Battery 3.8V – 5.45Wh – 1440mAh.
  • Something interesting: brings audio converter chip Digital-to-analog (and other way around) Apple 338S1077 Cirrus.
  • LTE modem for 4G mobile Internet connectivity.

Now we understand why at the launch of the are given so few details core processor Apple A6: the company had no way to explain to people that they were hosting the chip is good simply because they did it themselves, since it is not four nuclei as well as those sold competition and sight, has no feature that attracts attention: it is only dual core 1GHz barely runs.

We know that the design of the architecture is what makes the difference, but in this case, we are taking another leap of faith with the Apple A6, as no details were given of the design and to understand why this architecture designed by Apple, as being dual core and low frequency, is better than an ARM Cortex-A9 quad-core or dual-core A15 1.5GHz. It can be, no doubt, but we have to wait and see.
