Lenovo IdeaPad Yoga 13 Review: One Flexible Ultrabook
By

Test System Specs

We needed to compare the Lenovo IdeaPad Yoga 13 to a similar system. Being so unique, this proved problematic. Luckily, Dell also offers an Ultrabook that could give the Yoga a run for its money in the Southwest Regional Twister Championship. The similarly-priced and -spec'd Dell XPS 12 features that nifty flip-screen which first debuted in 2010 with the company's Inspiron Duo netbook.

The table below contains the pertinent specs of the Yoga 13 side-by-side with the Dell XPS 12:

Display

12.5" IPS @ 1920x1080

Both the Lenovo IdeaPad Yoga 13 and Dell XPS 12 incorporate similar QS77-based system boards. They also utilize the same third-generation Core i7-3517U processor with embedded Intel HD Graphics 4000, 8 GB of PC3-12800 RAM, and their own respective OEM versions of the PM830 128 GB SSD. However, there are a couple of small (yet noteworthy) differences that we need to be keep in mind.

First, the resolution of the Dell XPS 12’s IPS display is 1920x1080, while the Lenovo IdeaPad Yoga’s is only 1600x900. Secondly, the 8 GB SDRAM version of the Dell XPS 12 has two banks (2 x 4 GB) of DDR3 soldered directly to the system board versus the Lenovo’s removable single-module design.

Display Testing Methodology

The Spyder4Elite utilizes a full-spectrum, seven-color optical sensor and connects to the host PC via USB 2.0.

The raw screen data generated by the sensor through its manual placement around the display screen being tested is read by the included Datacolor menu-driven software suite and then efficiently plotted and graphed before walking the user through a simple and mostly automatic process of calibrating the screen.

Overall, the solution is very intuitive, easy to master, and provides some invaluable single (and multiple) screen testing and calibration capabilities for those who want their visual computing experience to be accurate and performing to its full potential.

We setup our display testing and calibration station in a dark room with the Yoga 13 connected to AC power while sitting on a flat surface. As usual, we are utilizing the Datacolor Spyder4Elite to record our screen measurements.

Tip: In order to ensure hardware accuracy, it is important to confirm the display of the test system itself is powered on for at least 30 minutes with no screen timeouts or other sleep modes enabled prior to the commencement of any testing and/or calibration of the display.

Booting Up!

After a very snappy 12-second initial boot time, we quickly navigate to the Windows Device Manager for a detailed view of the components inside our Yoga 13 sample.

Utilizing the widely-available HWiNFO64 utility, we can see in great detail just about every aspect of the Yoga 13’s hardware inventory, general specifications, and current operating status. Beyond the specific system board, processor, graphics, and drive reporting, we can also see that the system memory is only running is single-channel (asymmetric) mode.

Our Yoga 13 gets pretty solid Windows Experience Index scores for an Ultrabook. But as always, we take these ratings with a grain of salt, as they are simply reference baselines, not actual performance scores.
