The aarch64 instruction set has a madd instruction that performs integer multiply-adds. Cortex A725 and older Arm cores had dedicated integer multi-cycle pipes that could handle madd along with other complex integer instructions. Cortex X925 instead breaks madd into two micro-ops, and handles it with any of its four multiply-capable integer pipes. Likely, Arm wanted to increase throughput for that instruction without the cost of implementing three register file read ports for each multiply-capable pipe. Curiously, Arm’s optimization guide refers to the fourth scheduler’s pipes as “single/multi-cycle” pipes. “Multi-cycle” is now a misnomer though, because the core’s “single-cycle” integer pipes can handle multiplies, which have two cycle latency. On Cortex X925, “multi-cycle” pipes distinguish themselves by handling special operations and being able to access FP/vector related registers.

Both phones share a lot of core DNA, including compact designs, high-refresh AMOLED displays and similar camera hardware. The S26 does introduce a handful of meaningful updates, however, including a slightly larger battery and newer software out of the box. Those changes also come with a higher starting price: the Galaxy S26 begins at $899.99 compared to the S25’s $799.99 launch price. The entry model now includes 256GB of storage instead of the S25’s base 128GB. Here's how the Galaxy S26 compares with last year’s Galaxy S25 on paper and whether the newer model is worth your attention.
