Qualcomm wants TSMC to produce Snapdragon 855 mobile platform, not Samsung?
LG G4. This chip carried a hexa-core CPU.
By the end of next year, TSMC might start manufacturing the Snapdragon 855 SoC, and an unspecified modem chip. But there is no reason to hold a charity bake sale for Samsung. Next year, it is rumored to recapture the A-series chipset business from Apple that it had lost to TSMC with 2016's A10. Both Samsung and TSMC produced the A9 chip in 2015.
One reason why Qualcomm might favor TSMC for the Snapdragon 855 chipset has to do with the Taiwan based firm's lead over Samsung when it comes to the 7nm node. Like the Snapdragon 835 SoC, the Snapdragon 845 will also be produced with the 10nm process; if the Snapdragon 855 is to use the 7nm node, Qualcomm might feel more comfortable if TSMC is producing it.
