Sony is allegedly working on an in-house smartphone SoC
The Digitimes report, quoting the usual unnamed industry sources, says that Sony is planning to develop an in-house mobile SoC. Looking at the top smartphone manufacturers by global sales volume, most of those in the top five design their own chips. Apple designs its own AX chips, Huawei designs the Kirin chips, while Samsung designs and also manufactures its in-house Exynos chips.
Unfortunately, the report makes no mention of what to expect from Sony's first chipset. In the age of online leaks, it's unlikely that notable progress on such a major project would have been able to remain hidden from public eyes. Furthermore, even if Sony is indeed planning to design its own smartphone chip, we don't expect to see a Sony chipset powering the flagship smartphones from the Xperia Z lineup anytime soon.
