ASUS Zenbook A14 UX3407 OLED – Windows Copilot + Snapdragon (first look)

The ASUS Zenbook A14 UX3407 OLED is part of its Qualcomm Snapdragon X range for Windows Copilot+ PC.

It comes with the Snapdragon X Plus in the UX307QA and X Elite in the UX3407RA models. It is not ASUS’s first entrant. The VIVOBOOK S55O7Q was released in July last year, and it also has new Intel Core and AMD Ryzen AI Copilot+ PCs.

What is Copilot+ PC?

Importantly, it is not Copilot, a generative AI chatbot. It is a new PC (or laptop) breed designed explicitly for AI efficiency, including running Copilot and AI apps.

At its most basic level, it is Windows running on a 64-bit Qualcomm Snapdragon ARM processor with a Neural processor Unit (NPU). Together with the CPU and GPU, it is capable of AI processing at up to 45 TOPS (trillion operations per second). It must have at least 16GB of RAM and 256GB of storage.

Think of it as a more powerful mobile phone processor because it is based on that – not the traditional x86 Intel/AMD processors and instruction sets, although these companies now offer AI processors that meet or exceed 40 TOPS.

It runs many x86 apps in PRISM emulation (which can be slow) but mostly prefers x64 ARM apps. Microsoft has mandated that most popular x86 apps must be rewritten to natively support 64-bit ARM.

CyberShack’s view is that Windows on ARM is not for power users or those who rely on specific x86 software. However, it is fine for those who use Microsoft 365 and modern apps.

First Look: ASUS Zenbook A14 UX3407 OLED – Windows Copilot +PC Snapdragon

We put laptops and PCs through about 70 tests; regrettably, we wont finish these by the release date. The UX3407 models/variations go on sale on 11 March.
