The performance gap between these two devices is substantial and cuts across every measurable dimension. The Galaxy S25 256GB runs on the Qualcomm Snapdragon 8 Elite, a 3 nm chip that scores roughly 3,050,000 on AnTuTu and 10,050 on Geekbench 6 multi-core. The Galaxy S25 FE uses Samsung's own Exynos 2400, built on a 4 nm process, posting around 2,147,521 on AnTuTu and 7,000 on Geekbench multi-core. That is roughly a 42% lead in AnTuTu for the S25 — a difference that translates into noticeably faster app launches, smoother multitasking, and a more responsive experience under sustained load.
The RAM advantage compounds this further. The S25 carries 12 GB of RAM at 5300 MHz with a memory bandwidth of 85.1 GB/s, versus 8 GB at 4200 MHz and 64 GB/s on the S25 FE. More RAM means more apps can run in the background without being force-closed, and the faster memory speed accelerates data throughput to the CPU and GPU alike. On the graphics side, the S25's Adreno 830 at 1200 MHz outclocks the S25 FE's Xclipse 940 at 1009 MHz, reinforcing its edge in gaming and GPU-intensive tasks. The S25 FE does feature more CPU threads (10 vs 8), though this architectural breadth does not offset its lower clock speeds and benchmark scores in practice.
The Galaxy S25 256GB wins this category decisively. Its newer chip node, higher benchmark scores, more RAM, faster memory, and stronger GPU make it the clear choice for users who demand top-tier performance — whether for gaming, video editing, or simply keeping the phone feeling fast years down the line.
