Key Differences
-
The Pixel 10 Pro has 4 GB more RAM
The Galaxy S25 Ultra lists 12 GB; the Pixel 10 Pro comes in at 16 GB. That’s not a rounding error. Extra memory also gives the Pixel 10 Pro more headroom for heavier apps and for software updates in the years ahead.
-
The Galaxy S25 Ultra has 256 GB of base storage instead of 128 GB
At 256 GB versus 128 GB, this is a decisive lead for the Galaxy S25 Ultra, the kind of difference you notice without looking for it. Base storage is what you get without paying extra. Photos, videos and apps add up quickly, so more space at the entry price is real value.
-
The Galaxy S25 Ultra has a higher-resolution 200 MP main camera
If main camera is one of your priorities, this settles it: the Galaxy S25 Ultra leads clearly with 200 MP to the Pixel 10 Pro’s 50 MP. The Galaxy S25 Ultra’s higher-resolution main sensor gives you more room to crop, which helps when you can’t get closer.
-
The Galaxy S25 Ultra has faster 45 W wired charging
The numbers aren’t close. The Galaxy S25 Ultra lists 45 W for wired charging, while the Pixel 10 Pro lists 30 W. The Galaxy S25 Ultra refills faster on a cable, which matters most on the mornings you forgot to charge overnight.
-
The Pixel 10 Pro has 27% higher peak brightness
A clear win for the Pixel 10 Pro: 3,300 nits against 2,600 nits. Few specs in this matchup are as one-sided. Peak brightness decides how readable the screen stays in direct sunlight and how punchy HDR content looks.
-
The Galaxy S25 Ultra has an extra rear camera
Here the Galaxy S25 Ultra pulls well ahead of the Pixel 10 Pro, with 4 compared to 3. An extra rear camera usually means another focal length (ultra-wide, telephoto or macro) and more freedom in framing.

Display
Pixel 10 Pro leads
The Galaxy S25 Ultra has a tough time in the display section, where the Pixel 10 Pro pulls well ahead. The Pixel 10 Pro adds 27% higher peak brightness. If you use your phone outdoors a lot, the Pixel 10 Pro’s brighter panel is the one that holds up better at midday. The display verdict goes to the Pixel 10 Pro.
Peak brightness
Pixel 10 Pro: 3,300 nits Galaxy S25 Ultra: 2,600 nits Peak figures are usually reached only in short bursts or small areas of the screen, but a higher ceiling still helps outdoor visibility.
Screen size
Pixel 10 Pro: 6.3 in Galaxy S25 Ultra: 6.9 in A larger display also means a larger phone overall, so this is as much about your hands and pockets as it is about the picture.
Performance
Pixel 10 Pro leads
The Pixel 10 Pro is the clear pick if performance is what you care about most. In its favor, the Pixel 10 Pro has 4 GB more RAM. More RAM lets a phone keep more apps open in the background, so switching back to them is instant instead of a reload. The takeaway: on performance, the Pixel 10 Pro is the stronger phone.
RAM
Pixel 10 Pro: 16 GB Galaxy S25 Ultra: 12 GB Opening a single app, you won’t feel the difference. With lots of tabs, a game and the camera in rotation, the Pixel 10 Pro has more room to work with.
Memory & Storage
Galaxy S25 Ultra leads
Here the Galaxy S25 Ultra opens up one of its biggest leads in the comparison. The Galaxy S25 Ultra makes its case with 256 GB of base storage instead of 128 GB. If you shoot a lot of video or keep music and maps offline, base storage is one of the specs you’ll feel most over the years. Prioritize memory & storage, and the Galaxy S25 Ultra is where you should land.
Base storage
Pixel 10 Pro: 128 GB Galaxy S25 Ultra: 256 GB The Galaxy S25 Ultra starts with more room, which means fewer “storage full” warnings and less time deleting old videos.
Camera
Galaxy S25 Ultra leads
The Galaxy S25 Ultra clearly takes the camera round. Choose the Galaxy S25 Ultra and you get a higher-resolution 200 MP main camera. Megapixels are only one part of image quality, so treat this as a sign of detail potential, not a verdict on photos. The Pixel 10 Pro has the edge with a sharper 42 MP selfie camera. For anyone who cares most about camera, the Galaxy S25 Ultra is the safer choice.
Main camera
Pixel 10 Pro: 50 MP Galaxy S25 Ultra: 200 MP More megapixels on the main camera allow bigger crops and more detail in good light, but sensor size and processing matter just as much.
Rear cameras
Pixel 10 Pro: 3 Galaxy S25 Ultra: 4 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.
Battery & Charging
Galaxy S25 Ultra leads
For battery & charging, the verdict is easy: the Galaxy S25 Ultra leads, and not by a little. The Galaxy S25 Ultra comes with faster 45 W wired charging. Peak charging speeds depend on a compatible charger, which may not come in the box. Weighing only battery & charging, the Galaxy S25 Ultra comes out ahead.
Wired charging
Pixel 10 Pro: 30 W Galaxy S25 Ultra: 45 W Faster wired charging means a short top-up before you head out goes further.
Software & Updates
Too close to call
There’s little to choose between them when it comes to software & updates. So software & updates is a non-factor here; move on to the areas where they actually differ.
