Lenovo ThinkPad 10 Windows 8.1 Bay Trail Tablet

Performance: Web Browsing

We kicked off our objective benchmarking run by looking at Javascript and web browsing performance. Presumably these devices are going to spend a fair amount of time bouncing across cyberspace, and with the ThinkPad 10 running on a newer platform (Bay Trail) with a relatively strong foundation, we're expecting some pretty solid scores here.

Javascript & Web Browsing Performance
General Purpose Workloads

SunSpider 0.9.1 is a Javascript benchmark that has been around for a long time, so we have plenty of tablets to compare the ThinkPad 8 to, including one of its closest competitors, the Dell Venue Pro. Lower scores are better in this test. We also ran Browsermark, which runs the tablet through a series of tasks involving Flash, Silverlight, and HTML5, among others. Higher results are better in Browsermark.

ThinkPad 10 SunSpider

Lenovo's ThinkPad 10 starting things off in fine fashion by racing to the top of the charts. It scored 357.4ms in SunSpider, second only to Lenovo's own ThinkPad 8, which scored 326.6ms. They're the only two of the entire bunch to post scores lower than 400ms (note that lower is better/faster).

ThinkPad 10 Browsermark

Browsermark is a bit more rounded in its evaluation web performance. It focus on page loading, page resizing, conformance testing, network speed, WebGL, Canvas, HTML5, and CSS3/3D performance. The ThinkPad 10 leapfrogged ahead of the ThinkPad 8, joining the upperclassmen with scores of 3,000 or higher (unlike SunSpider, higher scores are better/faster in Browsermark). Comparatively, it was nearly a draw with NVIDIA's Shield handheld with only 24 points of separation.

One interesting thing to note is that the top five spots all belong to non-Windows platforms (iOS, Chrome OS, and Android). This is probably due to the additional overhead in Windows. That said, the ThinkPad 10 posted the highest score of any Windows-based slate.
