LG has announced have dismissed the ARM technology, prior to propose its own SoC for its aircraft. The Korean company will use the Cortex A9 and Cortex CPU and GPU A15 T604 Mali in its SoC. What is the benefit to its own SoC (System on a Chip)? First the price. When buying an LG chip in NVIDIA Tegra 2, there is room for NVIDIA and that of depth.
When LG produces its own SoC, there is only one of the caster, reducing the price. And companies like Samsung, able to burn the chips, further reducing the price. The second advantage comes from the ability to create a specialized chip. In most SoC, there are functions that are not used: ATA, MMC interface, management of I / O, etc..
The reason is simple: SoC chips are often aimed at different markets and therefore the functions are very numerous. By developing its own SoC, a company like LG may only includes the necessary functions and therefore offer a chip more suitable. Apple, with the A5, followed this path: SoC is very large (as permitted by the absence of intermediates) and includes only what is necessary with the sudden a complete processor (two cores + SIMD) and a GPU to two cores.
Finally, there is a reason marketing, at a time when the power of smartphones is brought forward (including LG): give a name to a very commercial processor and indicate that it comes from society itself is still a small effect. Qualcomm and Snapdragon or NVIDIA Tegra and 2 have understood this point, like Samsung and Hummingbird and Exynos (previously the company used only code names).
Remains to be seen when LG will release its chip: If developing a single SoC does not take much time, ARM offers effective tools, making it competitive by adapting parts of the chip is more difficult.
