Performance and Benchmarks
The UX31 uses a Low Voltage Intel processor; our model has a dual-core i5 chip. Another variant of this notebook includes a slightly faster dual-core i7 (for all practical purposes, the difference between the two will be unnoticeable). Paired with 4GB of system RAM the Core i5 is more than up to everyday tasks including the occasional foray into more demanding applications such as Adobe Photoshop. The included A-DATA 128GB SSD is blazing fast though our benchmarks show the write speeds to be a bit low. Regardless it is far faster than any hard drive.

Other highlights of the specifications include obviously the svelte dimensions and light weight but also the delightful 1600×900 screen resolution (a novelty in this size notebook) and two-year warranty, which is longer than most manufacturers. Note that unlike typical notebooks the UX31 does not have user-serviceable/upgradeable components. Those needing more storage should use an external hard drive.
