Samsung was earlier reported to stick with the Snapdragon 865 for its upcoming Galaxy S21 because the rumored price hike of the Snapdragon 875 would have ridiculously increased the cost of the company’s future flagships. Considering that even the base Galaxy S20 was stamped with a $999 price tag at release, things will start to look real dicey for Samsung when generating sales if the company sticks with the Snapdragon 875. Fortunately, Samsung is rumored to have an ace up its sleeve and that’s to omit the use of both the Snapdragon 875 and Snapdragon 865 in all markets. That is correct; Samsung might be going all-in with its own silicon.

A fresh tweet from someone who goes by the Twitter name ‘Your favourite Chun is back’ can ‘confirm’ that Samsung won’t be using the Snapdragon 865 for its Galaxy S21 series. Instead, the company may use the Exynos 1000, which is rumored to be the Korean giant’s upcoming silicon made on the advanced 5nm node, sporting Cortex-A78 performance cores and may rely on either the Mali-G78 or AMD’s RDNA GPU.
