iPhone 5s Teardown: étape 0, image 1 de 2 iPhone 5s Teardown: étape 0, image 2 de 2

  • It's time to investigate the new kid on the block, and it's fly like an A7. Along with the fingerprint sensor, the A7 is a major enticement for consumers to pick the 5s over the 5c.

  • The A7 is advertised as providing twice the performance of the 5 (and 5c)'s A6 processor.

  • The switch to the A7 marks 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gains do not come from any advantages inherent to a 64-bit architecture, but rather from the switch from the outdated ARMv7 instruction set to the newly-designed ARMv8.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.

  • We'll have to wait until we get inside the chip to find out who manufactured it.

この新しいチップを確認する時間です。A7攻撃機のように飛行するような気持ちです。指紋認証センサーも含めて、A7チップは、5cモデルよりも5sを手に取りたくなる魅力があります。

A7は5(同じく5cも)に搭載されているA6プロセッサの2倍のパフォーマンスを実現すると言われています。
