ASUS - Zenbook Duo (2024) vs ASUS - Vivobook S 14 OLED (2025)

The Zenbook Duo (2024) edges ahead on the Mars Score (68.1 vs 63.6), but the 4.5-point gap is small enough that the right pick comes down to which spec advantages matter to you.

Pick the Zenbook Duo (2024) 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, cpu cores, thunderbolt ports.

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 claimed battery life, weight.

Both ship with comparable storage, battery, screen size, 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.
