NEC Lavie Z Review — The World’s Lightest Ultrabook

Posted on 06 February 2013, Last updated on 08 March 2020 by


After spending time with the NEC Lavie Z, we’re ready to give you the full report. What’s obvious is the incredibly light weight of this device; it is hands-down the lightest Ultrabook we’ve seen — lighter even than many 11.6-inch Ultrabooks despite the Lavie Z being in the 13.3-inch class. Beyond the weight is the fastest CPU Ultrabook we’ve tested and a speedy SSD. In this review we’ll give you the lowdown on the build quality, aesthetics, performance, and more.

We’d like to thank Dynamism, importer extraordinaire, for providing the NEC Lavie Z for our review.

The NEC Lavie Z that we’re testing is powered by one of the fastest processors that you can find in any Ivy Bridge Ultrabook, the Intel Core i7-3517U @ 1.9GHz, which can use Turbo Boost to clock up to 3.0GHz (technical CPU specs here). Inside is also 4GB of RAM, HD 4000 graphics, and a 128GB SSD.

The display is 13.3-inches with a 1600×900 resolution. The NEC Lavie Z weighs in at 875g. This makes it lighter even than many 11.6-inch devices.
