Apple’s 20-nanometer A8 processor in the new iPhone 6 and 6 Plus was fabricated by Taiwan Semiconductor Manufacturing Company (TSMC), according to Chipworks. According to TSMC, its 20-nanometer process technology can result in speeds that are much higher than its 28-nanometer chips. The 20-nanometer process also results in a physically smaller chip that draws less power.
There were rumors whether Apple has ventured with Samsung or TSMC to manufacture the 20-nm A8 chip to be used in iPhone 6 and iPhone 6 Plus. The previous generation 28-nm A7 chip was manufactured by Samsung but this time Apple has entered into a partnership with TSMC to partially eliminate the dependency on rival firm Samsung and also to cut down potential manufacturing issues.
This news has also got surface which says Apple has ordered Samsung to make 14-nm chips which would be used for future Apple devices. Though we don’t have any exact document supporting the fact but it seems Apple might keep both the vendors to continue manufacturing chips for them.
According to Apple, the A8 chip in the iPhone 6 and 6 Plus offers a 25 percent faster CPU and 50 percent better graphics performance compared to the A7 in the iPhone 5s.
