Samsung plans to expand its entire SoC shipments network and further compete with Qualcomm. Qualcomm, on the other hand, has some plans of its own. It has long been rumored it will ditch Samsung for TSMC but subsequently, it appeared that the former semiconductor foundry lost interest in switching to TSMC.
According to current etnews, it was reported that in the next generation of the advanced 7nm node, Qualcomm currently chose to cooperate with TSMC. The previous 14nm and 10nm FinFET Snapdragon 820/821/835 has been used by Samsung but that may be changing soon. The cooperation between Qualcomm and TSMC cooperation is not new because they had some relationship in the development of Snapdragon 810 chipset.
Qualcomm’s first 7nm may be Snapdragon 845, but if the news is true, it may have a later model because TSMC needs till the end next year to commence mass production. Thus Snapdragon 845 and 836 will still be based on the 10nm process but the difference is that the frequency is higher, and the process will be advanced to more mature, less leakage of LPP.
Benchlife earlier reported that Samsung 10 / 14nm have been able to grab Qualcomm, mainly because of risk trial production and in accordance with the film offer charges. TSMC is in accordance with the wafer charges and the price is also slightly higher, so you have to wait for good enough time to control the yield.
