Performance

Our Lenovo ThinkPad Twist 3347-4HU review unit has the following specifications:

  • Windows 8 Home Edition 64-bit
  • 12.5 HD IPS display with Touch Sensor, 350 Nit (1366 x 768), Gorilla Glass
  • Intel Core i5-3317U 1.7 GHz
  • Intel HD Graphics 4000
  • 4GB DDR3
  • 500GB (5400RPM) + 24GB mSATA
  • Intel Centrino Wireless-N 2230
  • Bluetooth 4.0
  • Integrated HD Webcam
  • No Internal Optical Drive
  • 4-Cell 43 Wh LiPolymer
  • 12.3″ x 9.3″ x 0.8″
  • 3.48-lbs
  • $899.00

The Lenovo ThinkPad Twist 3347-4HU offers performance on par with mid-tier notebooks, though that may be problematic, since the price tag of $900 (at time of review) is edging towards the cost of high performance machines. 

Equipped with a third generation Intel Core i5-3317U 1.7GHz dual-core processor, 4GB of RAM, and Intel HD Graphics 4000 the ThinkPad is able to easily handle basic word processing and computing functions. The notebook is also able to handle multi-tasking fairly well, though I did notice a bit of lag when running multiple programs (particularly video streams) at the same time.

Users looking to perform more hardware intensive functions such as gaming will notice the machine’s lack of performance. While the integrated graphics can handle Photoshop, basic HD video editing or play games with modest system requirements, the performance levels are a pittance compared to what dedicated Nvidia or AMD graphics card can offer.

Heat and Noise
The Lenovo ThinkPad Twist 3347-4HU houses a single fan located on the right side of the chassis. The single fan proves to be more than enough for the ThinkPad as the device remains comfortably cool even when the machine is pushed to its limit. Additionally the fan remains silent, and is only audible when users are extremely close to the device.

Battery Life
To test battery life we used our new Windows 8 benchmark, PowerMark in balanced mode. The test consists of combination of automated web browsing, word processing, gaming, and video playback workloads. The new test is far more strenuous than our previous test, measuring the machine under a litany of scenarios to better simulate real life use. The new test is far more demanding on our machine causing the scores to understandably be lower than our pervious benchmark.

PowerMark battery life test results (higher scores mean better life):

The Lenovo ThinkPad Twist 3347-4HU ran for 2 hours and 24 minutes on its 4-cell 43 Wh LiPolymer Battery before the device shut down, after reaching the 5 percent battery limit reserve. The ThinkPad’s battery is easily the weakest facet of this machine. Despite its sturdy chassis design, the weak battery life will greatly hinder this device’s portability. Granted, in a typical workplace environment with light usage the ThinkPad Twist should deliver more than five or six hours of battery life while connected to Wi-Fi … but that’s still less than the competition. Luckily the device is lightweight, so traveling with the notebook and charger should not be too much of a problem.
