Basically every Galaxy phone comes in two versions. One with Exynos and one with Snapdragon. It's regional though. US always gets the Snapdragon phones while Europe and mostly Asia gets the Exynos version.

My understanding is that the Exynos is inferior in a lot of ways, but also cheaper.

In the past using Snapdragon CPUs for the U.S. made sense due to Qualcomm having much better support for the CDMA frequencies needed by Verizon. Probably no longer relevant since the 5G transition though.
