Apple has alerted developers to update their existing apps from 32-bit to 64-bit to make use of the new A7 chip of the iPhone 5s. The iPhone 5s brings a host of new changes to the table, but one of the most impressive, perhaps, is its new A7 chip. The A7 chip boasts incredible 64-bit performance.

Developers such as Chair, creators of the Infinity Blade franchise, have already made use of this new advancement. Their latest game, Infinity Blade III is optimized for the iPhone 5s’s 64-bit processor. Infinity Blade III is set to launch on Wednesday.
