Start64!Apple's announcement of a 64-bit processor has the tech world debating just how far the mobile world is from upgrading its instruction set architecture - Apple Inc, in its not-so-glitzy launch show last week, made a new marketing pitch that wasn’t just about its sleek design or its funky interfaces. It announced an upgrade to the A7 microprocessor for the latest version of the iPhone, popularly called iPhone5.

But what’s new about this microprocessor? Apple is basking in the glory of beating the competition by being the first smartphone maker to announce chips that sport a brand new 64-bit instruction set. The v8 architecture, licensed from ARM Holdings, replaces the v7 used in the A6 processor that powered earlier versions of the iPhone. Apple’s Phil Schiller announced that the new chipset offers "huge benefits" including increased speed on processors and graphics.
