Expert Analysis
All three are the same premium Zenbook 14 OLED concept — a colour-accurate 2880×1800 OLED in a sub-1.4 kg aluminium chassis with a 75 Wh battery — so the upgrade case is driven by the silicon, the panel's refresh rate and the connectivity rather than any change in class. The 2023 UX3402 (i7-1360P) is the clear outlier to retire: it caps at 16 GB of memory, has only a single Thunderbolt 4 port, a 90 Hz panel and no NPU, and on Raptor Lake it is the least efficient of the trio. The 2024 UX3405 (Meteor Lake Core Ultra 7 155H) closed most of that gap — dual Thunderbolt 4, a 120 Hz OLED, 32 GB ceiling and a basic NPU — and remains a perfectly capable hybrid-work machine. The current Core Ultra Series 2 model adds Wi-Fi 7, a brighter panel option, meaningfully stronger CPU and graphics, and a genuine Copilot+ NPU on the Lunar Lake configurations. One caveat for fleet buyers: the Zenbook line is a consumer-premium platform without Intel vPro, so organisations that mandate out-of-band management should treat all three as Windows 11 Pro / Intune devices rather than vPro-managed endpoints, and look to the EliteBook or ThinkPad lines where vPro is non-negotiable. Our UK guidance: refresh any 2023 UX3402 units now, especially the 16 GB models; hold a healthy 2024 UX3405 to its natural cycle unless Wi-Fi 7 or Copilot+ is needed; and specify the current Series 2 model (Lunar Lake SKU for AI, Arrow Lake-H for peak multi-core) for new executive and design-lead deployments.
