Lenovo ThinkPad X1 Tablet Review: A 2-In-1 For Pros

To start things off, we take a look at how the Lenovo ThinkPad X1 Tablet handles web browsing, and specifically JavaScript, along with a PCMark 8 run to see if everything is working properly and firing on all cylinders.

SunSpider JavaScript Benchmark JavaScript Performance Testing

SunSpider is a well-known JavaScript benchmark. The test is designed for comparing browsers to each other, so it’s worth pointing out that different Web browsers can have an impact on scores.


We have a mountain of scores to compare SunSpider results to, and out of all of them, the ThinkPad X1 Tablet takes second place behind Dell's XPS 15. That's an impressive showing, albeit not unexpected from a clean system that pairs a Core m7-6Y75 with 8GB of LPDDR3 1866MHz RAM.

PCMark 8 Productivity and System-Level Benchmarking

Futuremark’s PCMark 8 runs the system through typical home and work activities and provides individual scores for certain task categories, rather than specific hardware. The Home test is just as it sounds: a collection of everyday tasks, including web browsing and chatting. The Work test is more demanding and has business-oriented tests, while the laptop’s SSD gets workout in the Storage test.


Lenovo's ThinkPad X1 Tablet again shot up towards the top the pack with second place finishes in PCMark 8's Home Accelerated and Work Accelerated benchmarks, and finishing strong in the Storage test. This underscores the punch that Intel's Skylake-based Core M processor family packs, and in particular the Core m7-6Y75 is proving itself a chip to be reckoned with. The Core m7-6Y75 is no slouch—though it's only a dual-core CPU, it supports Hyper Threading, has 4MB of cache, and can ramp up to 3.1GHz as needed.
