Most of next year’s flagship smartphones would be fueled by the successor to the Qualcomm Snapdragon 845 SoC. However, contrary to popular belief, the upcoming chip would not be called the Snapdragon 8150 SoC. It is hard to say what the chip would be called, as Qualcomm hasn’t dropped any hints but it won’t be long before we find out as the company will announce its flagship silicon at the three-day Snapdragon Technology Summit starting on December 4. The event is expected to focus heavily on 5G and we can also expect new product announcements from laptop and phone manufacturers.

As for who started the Snapdragon 8150 rumor, it is hard to trace it back to the originator, but apparently, the confusion arose when the internal name sm8150 was assumed to be a marketing name as well. Qualcomm is fond of changing the naming convention of its chipsets every now and then. It first began with the ‘S’ moniker (S4 chipset), and then shifted to the current naming scheme.
