Lenovo ThinkPad L440 - take it to university right away?
Lenovo ThinkPad L440 - take it to university right away?

联想为型号为20AT004QGE的ThinkPad L440配备了更强的HD+屏幕和固态硬盘。不过，这仍然无法让它算是一款实惠型高端专业笔记本。这块屏幕仅200:1的对比度十分惨淡，而它的DeltaE色差指数也非常高。配备HD+屏幕的竞争对手，Latitude 3440和ProBook 640 G1相比之下屏幕质量都更高（对比度）。配备固态硬盘的ProBook售价仅高出50欧元（约382人民币），而Latitude 3440尽管专业功能（输入设备，接口，机身）更少，它配备GT 740M显卡的型号售价仅670欧元（约5129人民币）。

不论如何，我们的测试机在应用程序性能上领先于其他用于对比的机型，由于它们都采用了传统硬盘(Latitude 3440, ProBook 640 G1)，其中有一些采用了较弱的低电压版本处理器(Latitude 3440)。它的处理器可以发挥全部的加速性能，而不会有过热降频的问题。对于注重性能的用户，除了用于游戏用途外，配备固态硬盘的ThinkPad L440都是个完美的选择。
