According to a fairly reliable source, Samsung is reportedly going all-in on Qualcomm's Snapdragon chips for Galaxy S25 and Galaxy S26.

If Samsung does exclusively use the Snapdragon 8 Elite in the Galaxy S25 line, then that will probably mostly be good news. It will mean for one thing that whichever S25 model you buy in whatever region, you’ll get an equal amount of power (other than possible RAM differences).

A reliable Samsung leaker says all Galaxy S25 models will get the new Qualcomm Snapdragon 8 Elite chip, not just the Ultra.
