The A7 Processor
  • As promised by Apple, and most recently confirmed by Gizmodo via the magic of benchmark testing, the A7 provides twice the performance of the A6 processor.

  • The A7 is the first use of a 64-bit processor in a smartphone. Based on AnandTech's review, it seems that the bulk of the A7's performance gains do not come from any advantages inherent to a 64-bit architecture, but rather from the switch from the outdated ARMv7 instruction set to the newly-designed ARMv8.

  • The modern ARMv8 instruction set was designed for a 64-bit architecture. It does away with the legacy support of the last 20 years, which increases efficiency, improving performance without sacrificing battery life.
