Lenovo ThinkPad X100e Performance, Benchmarks and Conclusion

Performance and Benchmarks
When we first tested the AMD Athlon Neo MV-40 processor inside the HP Pavilion dv2 more than a year ago we were reasonably impressed by the performance. While this single-core processor was an excellent choice in 2009 it is starting to show its age in 2010. The Athlon Neo certainly performs better than a single-core Intel Atom processor, but for roughly the same price you can buy a netbook equipped with a dual-core Atom or Intel CULV processor that delivers faster multitasking and quicker application switching.

In terms of day-to-day activities like working with Microsoft Office or browsing the web it’s fair to say that most business users won’t notice much (if any) performance difference between the ThinkPad X100e and an Intel Atom-based netbook. HD video playback for both 720P and 1080P content was flawless, and unlike Intel-based netbooks, the ATI Radeon 3200 graphics are powerful enough to handle video without stressing the processor. This means you can run Office and a video player at the same time without as much lag.

Indeed, if you compare the X100e against a typical netbook with a single-core Intel Atom processor and Intel integrated graphics then the X100e is an obvious winner. Unfortunately, the performance of the X100e looks less impressive compared to dual-core Atom netbooks and netbooks with Nvidia ION now on the market.

Heat and Noise
Noise levels were average during normal daily use. The default fan speed is always on at a low setting, pushing hot air away from the CPU and out of the notebook. The fan doesn’t get much louder even if you stress the system with a game or video encoding. Unfortunately, the quiet fan means you get higher than normal case temperatures when the notebook is left on for more than 30 minutes. The external case temperatures on the X100e are quite a bit higher than similar-sized netbooks and ultraportable notebooks on the bottom surfaces. The bottom of the X100e nearly reached 110 degrees Fahrenheit after 40 minutes of moderate use (one wPrime test, watching several YouTube videos, and typing a text document). This makes the X100e less “lap friendly” than business netbooks like the HP Mini 5102. You’ll probably want to keep it on an airline tray table or a hotel desk when working on the road. All temperatures shown below are listed in degrees Fahrenheit.

Battery Life
Although the AMD Athlon Neo MV-40 processor offers as much (or more) performance than the Intel Atom in day-to-day tasks, the AMD processor simply didn’t deliver as much in the way of battery life. In our battery test with the screen brightness set to 70%, wireless active, and Windows 7 set to the “balanced” profile the system managed 3 hours and 41 minutes before shutdown. This is more than enough battery life for business travelers who are only crossing a few time zones during a flight, but if you need “all day” battery life you aren’t going to find it here.

Granted, it wasn’t too long ago that we used to praise any notebook that delivered more than three hours of battery life. Unfortunately, the ThinkPad X100e competes against netbooks and ultraportables that get six or more hours of battery life on a single charge. Three and a half hours might be “acceptable” to most business professionals, but it isn’t as impressive as the competition.

Conclusion
The ThinkPad X100e is an extremely well-designed business ultraportable that will no doubt meet the needs of most business travelers who are looking for a small, ThinkPad-quality laptop at a low price. That said, this configuration of the X100e falls short in two key areas: processor performance and battery life.

Lenovo should have avoided using last year’s single-core AMD processor and stuck with the latest generation of low-voltage dual-core processors from AMD. Lenovo will begin shipping the X100e with the dual-core AMD Turion Neo processors soon, and the higher performance and better battery life of the new processors will make the X100e a far more compelling option.

As it currently stands, the ThinkPad X100e is a surprisingly solid little netbook (Yes, I called it a netbook. Sorry, Lenovo.) that would have been perfect if it delivered just a little more in terms of performance and battery life. This configuration falls just a little short of earning our Editor’s Choice Award, but we still think it will be a popular choice for a number of business buyers.

Pros:

• Great keyboard
• Good integrated graphics performance
• Solid build quality at a low price

Cons:

• Weak processor (as configured)
• Average battery life
• Keyboard not backlit
