The iPhone 7 could take the place of iPhone 6s as fastest Apple smartphone with rumored A10 processor to be used in the device. TMSC will purportedly manufacture the A10 processors, not Samsung or Intel.

BGR reported that a message posted in Weibo was the source of iPhone 7 processor rumor. An unverified source said that Apple will be making the leap from an A9 chipset to an A10 processor which will boast six cores. If the rumors are true, the iPhone 7 will have an unbelievable speed comparable to a new Retina MacBook.

Many users think that iPhone 6s is the fastest smartphone with its A9 processor. If the next iPhone will sport an A10 SoC, it will be even more powerful and efficient, reported Cult of Mac. The iPhone 7 will become "an unbelievable speed machine".

Production of the rumored A10 processors could begin as early as March next year. The next-gen A10 processor will utilize InFO (integrated fan out) architecture that will focus on multi-threading development, according to Apple Insider. The InFO will reportedly cut down costs and streamline production.

Another rumor buzzing about is that TMSC will be Apple's manufacturer for the A10 chipset. It was reported that Samsung, Intel, and TMSC are competing for Apple's order.

The iPhone 6s and 6s Plus processors were manufactured by both TMSC and Samsung. But it seems that Apple will be sticking only with TMSC for its future A10 SoCs.

However, Apple expert Ben Bajarin said that Apple would more likely focus on improving GPU instead of investing in upgrading the iPhone's processor. Yet, the source of the iPhone 7 chipset rumor has already made accurate predictions in the past regarding A9 processors.

With the iPhone 6s and 6s Plus just launched recently, an iPhone 7 and a probable 7 Plus will likely not be made until next year. iPhone fans are advised to take iPhone 7 rumors with a grain of salt for now.
