All three devices within the Samsung Galaxy S21 series are flagships by virtue of them sporting the latest Samsung Exynos 2100 SoC. This is the latest flagship SoC from Samsung, going head-to-head against the Qualcomm Snapdragon 888 flagship SoC.

Move past the SoC, and you'll see clear differences between the three devices in the lineup. The most prominent difference is their size and display resolution, followed by build materials, and finally the rear camera setup. A few other small details also differentiate the Galaxy S21 series specs. While the Galaxy S21 Ultra is obviously the premier champion within the lot, the Plus variant and the regular can also be viable options in their own right.
