Unknown A6 processor details: Why use ARM "size core"?

Iphone5 is driven by the powerful Apple A6 processor, suspected of being made by South Korea’s Samsung OEM. According to UBM TechInsights' preliminary chip-level reverse engineering disassembly, it is suspected that the A6 processor chip uses ARM's "size core" graphics processor core architecture.

Based on the foundry status of Samsung's previous generations of iphone series processors (such as A4 and A5), many people have speculated that the iphone5 A6 processor foundry is not Samsung. However, due to the dispute between Apple and Samsung, the patent dispute, some analysts pointed out that Samsung A6 foundry status may also be replaced by TSMC.

UBM TechInsights dismantling experts pointed out that the A6's chip die tag is similar to the A4 and A5 processors.

Unknown details about the A6 processor:

UBM TechInsights revealed a detailed question about the A6 processor - only three graphics processor cores are easier to identify.

The above shows that the Apple A6 processor may use ARM's "size core" technology, which uses a high-performance processor core and a power tuning processor core to divide the data processing for the cache, and its flexible pressing Handle the amount of data to perform core conversions, thereby reducing overall power consumption.

Analysis of the reasons: Apple attaches great importance to the product battery and chip power consumption experience, about the use of ARM architecture to design Apple processor has long been heard, and now finally put into practice. It can be seen that compared with the Intel X86 architecture, Apple is more inclined to low-power ARM architecture kernel. This may be able to predict the future mainstream evolution of mobile device product processors, Intel has a long way to go in order to occupy a place in the field of mobile processors.
