Apple iPhone 7 failed to fully exploit the performance of processors

This week, Qualcomm filed a counterclaim against Apple, accusing the chip maker in that it requires too high a fee for using its patents. The company said that the iPhone maker uses the power of processors in their smart phones not fully.

In January, Apple has accused Qualcomm that requires payment for “technology, to which it is irrelevant”. The chip maker filed a counterclaim, which will be considered in the district court of the state of California.

“Apple has been able to build an incredible business on the iPhone, which made it the most profitable company in the world, receiving more than 90% of the profits in the smartphone market without relying on the fundamental technology of Qualcomm. Now, after a decade of growth, Apple refuses to acknowledge the value of these technologies”, – said in a statement Qualcomm.

Qualcomm noted that Apple has not fully revealed the potential of system-on-chip A10 Fusion in the iPhone 7 and iPhone 7 Plus. This SoC with a 4-core processor has become a key innovation of the flagship smartphone of the “Apple” brand. Since the iPhone was first used by a SoC developed by Apple (A4), the company does not consider it necessary to equip their hardware with more than two cores ARM. The goal of the creators SoC A-series was and remains the most effective extraction of parallelism from single thread of instructions.

All generations of the iPhone, succeeding over the years, this approach has proved its efficiency, allowing Apple to compete with mobile SoC that has four or more cores (as licensed from ARM design and based on original IP), in such a resource-intensive and typical smartphone tasks like web-surfing and 3D games.

Apple’s A10 Fusion includes two dual-core cluster and a hardware controller that performs the migration of tasks between the latter. The word “migration” means that the high-performance and energy-efficient clusters never work simultaneously, and at the time of disconnecting one of the clusters, it passes the data to the second cache through the shared L2.

Apple’s A10 Fusion is manufactured at TSMC on the 16 nm FinFET technology and has an area of 125 mm2, 20.5 mm2, exceeds the area A9 is also manufactured by TSMC. If you rely on an independent assessment of the number of transistors in both SoC (more than 2 billion and 3.3 billion respectively), the A10 Fusion achieved significantly greater density of components compared to the first experience of the applications of 16 nm FinFET process technology from Apple.

According to the recent AnTuTu performance rating, the iPhone 7 and iPhone 7 Plus in March ranked first in performance among all the mobile devices on the market. The current leader of the iPhone 7 Plus with an average score 181 494 points ahead of the most powerful Android smartphone OnePlus 3T almost 20 000 points.
