Samsung Galaxy S25 Ultra review – head-turning power and all-encompassing AI
Share:
The Samsung S25 Ultra is a welcome refashioning of a favorite. It's got a bigger screen and a clean design that better reflects its family. The biggest update, though, comes through a generous helping of AI that touches both hardware and software. This may be the most complete AI-ready mobile package on the market.
+ Unified design that doesn't skimp on Ultra appeal. Biggest screen of the lineup. Powerful AI. Still missing 10x optical zoom. No screen technology updates.

Goodbye, all those Note vestiges, and hello to new, or at least more consistent, design language. The all-new Samsung Galaxy S25 Ultra finally looks like a part of the Galaxy S Family, sharing the same flat band wrapping around its body. For this latest flagship, Samsung has recast the Galaxy S25 Ultra in the image of its siblings while maintaining that Ultra flair with premium materials, the largest screen, and, yes, the integrated S Pen.
Like the rest of the line, the S25 Ultra now features Qualcomm’s best mobile CPU, the 3-nanometer Snapdragon Gen 8 Elite for Galaxy, which promises to be faster and more efficient than anything the Galaxy S line has run before. Samsung told us this is actually a custom version of the processor, but didn’t go into detail.
While we’ve not yet had the time to benchmark the new phone – we’ll be doing that for our full review – the company did note that the NPU could be 40% faster, the CPU is, as they measure it, 37% faster than the last Ultra, and the GPU is, they promise, 30% faster. Even ray tracing gets a boost with Samsung’s benchmarks finding it 40% better than the S24 Ultra’s Ray Tracing capabilities. Put another way, this might be a very good gaming smartphone.
