Lenovo Yoga Book Review: A 2-In-1 With A Trick

We kicked off our tests with SunSpider, a JavaScript benchmark, and then run PCMark 8, which will give us a comprehensive look at the Yoga Book’s capabilities. When comparing the Yoga Book’s score to other mobile devices, it helps to keep in mind that its price tag is $549.99, which puts it closer to entry-level than high-end tablets.

SunSpider JavaScript Benchmark JavaScript Performance Testing

We should note that SunSpider is more of a platform test, in that different browser versions, associated with different OS types can and do affect scores. However, among the Windows 10-powered machines here, all things are relatively equal.


The Yoga Book doesn’t appear to have much firepower. Anyone looking at the tablet as more than a tool for sketching or taking notes will want to keep that in mind. 

PCMark 8 Benchmarks Productivity And System-Level Benchmarking

We selected three tests from the PCMark 8 benchmark suite: Home, Storage and Work. Futuremark recently improved all three tests with PCMark 8 version 2. We selected the Open CL "Accelerated" options for both Home and Work.


Here again, the Yoga Book produced fairly low scores. The tablet handles ordinary Web browsing and video streaming without much trouble, but users who open several programs at once or take on resource-intensive tasks (like heavy photo- or video editing) will want more power than they’ll get from the Yoga Book.
