Unveiling the results of its A7 teardown on Tuesday, iFixit got the inside scoop on the chip thanks to some electron microscope scanning from Chipworks. The teardown uncovered more than 1 billion transistors built into the processor.
But even further, Chipworks found that the transistors are more tightly packed. The distance between each transistor in the A7 is 114 nanometers, an advancement over the A6's 123 nanometer gap. The improvement is possible … Read more
