A10 Fusion
This last couple of days, Apple and its most loyal clients were ecstatic with the launch of the latest iPhone variant - iPhone 7 and iPhone 7 Plus. They lauded all the unique features and the way the smartphone look and feel.

However, what makes the two iPhones unique and powerful is the source of it power inside.

Powering Apple's new iPhone 7 and iPhone 7 Plus smartphones is a new chip called the A10 Fusion. Why Apple added the word Fusion to the name is unknown, and beyond the obvious. Maybe Apple wants to distance itself from a weapon of war. Or maybe it has something to do with AMD's A10 chips. It is not certain.

The A10 Fusion is Apple's first quad-core mobile SoC (System-on-Chip), and it consists of two high-performance cores for demanding applications, and two energy-efficient cores for regular usage.

Which cores are used is controlled by an Apple-designed performance controller.

The low power cores operate at a fifth of the power of the high-performance cores. This is similar technology to ARM's big.LITTLE technology, which isn't surprising given that Apple licenses ARM technology for its chips.

The chip contains 3.3 billion transistors. Compare this to Intel's original P5 core Pentium released in March of 1993, which contained 3.1 million transistors.

According to Apple, the A10 Fusion has 40 percent more CPU performance and 50 percent more graphics performance compared to the A9 chip found in the iPhone 6s. Sounds impressive, but the numbers suggest that how much power Apple can squeeze out of its silicon is slowing down given that the A9 chip was a whopping 70 percent faster than its predecessor.
