The Galaxy S6 and S6 edge a 14nm Exynos 7420 mobile processor providing increased processing speeds. The 14nm FinFET Exynos 7420 Octa-core processor shows speeds of 2.1 GHz for Cortex-A57 cores and 1.5 GHz for Cortex-A53 cores.
The smaller manufacturing size indicates a shorter transistor distance, which translates to lower energy consumption and a boost in processing speeds. Meanwhile, because the transistors were now packed more tightly together, there was the risk of current leakage between parts of the chip. FinFET manufacturing addressed this issue by enclosing the conducting channel in a thin silicon "fin".
The 14nm processor supports the new 64-bit CPU. The new Android Lollipop operating system is also optimized for 64-bit processors. Plus, the new devices come with LPDDR4 memory systems, which means there’s around a 30 percent performance boost compared to the LPDDR3 used for previous models. (*Based on laboratory testing.)
The internal memory on the Galaxy S6 and S6 edge uses the new UFS (Universal Flash Storage) 2.0 standard, giving you faster boot time, copy and file transfer time without compromising battery power or memory performance.
This new technology combines eMMC’s low power consumption and the SATA interface’s high performance for optimized performance. This means you can watch videos, run multiple applications, play high bandwidth games and download large files without causing lags or delays.
UFS 2.0 is essentially the equivalent of taking your PC’s SSD storage and fitting it into your Galaxy S6. This is possible because UFS 2.0 has separate read/write paths for the LVDS (Low-Voltage Differential Signaling) serial interface that allows simultaneous data receipt and transmission for faster data processing.
Over the next several years, Samsung will continue to set the pace for memory solutions that combine high-performance with high capacity. Keep an eye out for developments.
