Lenovo - ThinkPad X9 14 Gen 1 vs ASUS - Vivobook S 14 OLED (2025)

The Vivobook S 14 OLED (2025) edges ahead on the Mars Score (59.4 vs 63.6), but the 4.2-point gap is small enough that the right pick comes down to which spec advantages matter to you.

Pick the ThinkPad X9 14 Gen 1 if you push the hardware — gaming, on-device AI, heavy multitasking — and the extra compute headroom is worth the trade-offs. The biggest gaps in its favor are ram, thunderbolt ports, weight.

Pick the Vivobook S 14 OLED (2025) if your top frustration with your current device is running out of charge before the day ends — endurance is the lead spec here. Its strongest claims are battery, cpu cores, claimed battery life.

Both ship with comparable storage, screen size, refresh rate, so those specs do not separate the two — focus on the differences below.

Bottom line: there is no wrong answer here — match the spec advantages to how you actually use the product. The Mars Score parity says both are well-rounded; the differences are about trade-offs, not quality.
