The Apple A4 is a microprocessor designed by Apple and manufactured by Samsung[1] and first used in the iPad tablet computer,[2] then in the iPhone 4 smartphone.[3] It was also used in the iPod Touch (4th generation).

History[change | change source]

Apple announced the A4 on January 27, 2010, during their "Latest Creation" event.[2]

On June 7, 2010, Steve Jobs publicly confirmed that the iPhone 4 would contain the A4 Processor, although it was not yet known if it had the same frequency, bus width, or caches as the A4 in the iPad.[3]
