ThinkPads have traditionally been light on pre-installed software and the X1 follows the same trend. Aside from an installation of the Bing Bar, there wasn’t any other questionable software to bog the system down. Trial versions of Microsoft Office 2010, Skype and Norton Internet Security are provided, but Lenovo leaves it up to the end user to decide whether or not to install these. Lenovo installs plenty of their own software such as the ThinkVantage Toolbox, which is a suite of programs that cover things like system health, security, networking and diagnostics. Lenovo’s custom power management program, Power Manager 3, is also included and set to a medium power / energy saving profile by default. Fresh out of the box, the X1 takes roughly 45 seconds to boot into a ready-to-use state of Windows. Intel’s Turbo Boost 2 is also part of the new second generation Core series chips and is designed to better manage workloads by dynamically adjusting individual core speeds depending on the processing power is needed. The Core i5-2520M in our unit is clocked at 2.5 GHz and should ramp up to 3.2GHz as needed. Below we’ve included our standard suite of benchmark numbers tests run on the ThinkPad X1 to give you an idea of how the system performs under load.

The iTunes encoding tests consist of converting 14 MP3s (119MB) to 128Kbps ACC files and measuring the operation’s duration in seconds. For the file transfer test, we measure how long it takes to copy two sets of files from one location to another on the same hard drive. On the small files test we transfer 557 MP3s, totaling 2.56GB. For the large file, these same MP3s were zipped into a single file measuring 2.52GB.
