Key Differences
-
The Pixel 9 Pro XL has 4 GB more RAM
Not a close call. The Pixel 9 Pro XL lists 16 GB and the Galaxy S25 Ultra lists 12 GB. That’s a substantial gap. More RAM lets a phone keep more apps open in the background, so switching back to them is instant instead of a reload.
-
The Galaxy S25 Ultra has 256 GB of base storage instead of 128 GB
Among all the differences on this page, 256 GB against 128 GB is one of the most meaningful, and it favors the Galaxy S25 Ultra. The Galaxy S25 Ultra starts with more room, which means fewer “storage full” warnings and less time deleting old videos.
-
The Galaxy S25 Ultra has a higher-resolution 200 MP main camera
The Pixel 9 Pro XL gives up a lot on main camera: 50 MP, compared with 200 MP on the Galaxy S25 Ultra. Megapixels are only one part of image quality, so treat this as a sign of detail potential, not a verdict on photos.
-
The Galaxy S25 Ultra has an extra rear camera
Few buyers will miss this one. The Galaxy S25 Ultra brings 4 to the table; the Pixel 9 Pro XL brings 3. More cameras help most when each covers a different view, so check the table to see what the Galaxy S25 Ultra’s extra lens adds.
-
The Pixel 9 Pro XL has a sharper 42 MP selfie camera
When it comes to front camera, the Pixel 9 Pro XL wins comfortably with 42 MP against 12 MP. A sharper selfie camera helps with video calls, vlogs and group selfies.
