The forum post mentions that talks between Samsung and a former Apple employee who lead the development of the company’s architecture are almost over. It also states that an ex-Apple employee is demanding from Samsung the right to create a project team selecting his own team members. It isn’t totally clear whether this former Apple engineer is the same person mentioned at the start of this paragraph.
Samsung does own a chip manufacturing foundry unit that produces its own Exynos line of chips and Qualcomm’s 5nm Snapdragon 888 chipset that powers current flagship Android phones. While Samsung’s Exynos chips are based on ARM’s Cortex architecture, the post on Cien.net suggests that Samsung is turning to a custom architecture to improve the performance of its home grown chips.
Considering the source of this rumor, and the variations that might have occurred in translation, we would warn you to take the report with a grain of salt.
