After sticking with TSMC for two years (2019 and 2020), Qualcomm came back to Samsung for its latest high-end chipset. The company's latest flagship processor, the Snapdragon 888, is built using Samsung's 5nm EUV fabrication process.

The dark satanic rumour mill had manufactured a hell on earth yarn claiming that Qualcomm could switch back to TSMC for its next-generation flagship processor.

However according to a more reliable leaker, Roland Quandt, Qualcomm is already testing the Snapdragon 888's successor, the SM8450 (codename Waipio), and that Samsung Foundry will make it. However, it is still not clear if the next-generation chipset will continue to use the 5nm LPE process or something more flashy.

Both Exynos 2100 and Snapdragon 888 use Samsung's 5nm process, and studies show that the South Korean chip firm's 5nm LPE process is only as good as TSMC's 7nm process in terms of power efficiency.

 Qualcomm is believed to be launching the SM8350 Pro (Snapdragon 888+ or Snapdragon 888 Pro) later this year, and Samsung is likely to make it.

Samsung already makes Qualcomm's latest 5G modems—Snapdragon X62 and Snapdragon X65—using its 4nm process. Qualcomm's next flagship processor could either use the same 4nm process or use the upcoming 3nm GAA technology, which is said to bring much better power efficiency compared to Samsung's 5nm and 4nm processes.
