Dell Latitude 14 E7450

你不需要每次都发明一种新的轮子——一点点地改进已有产品也是个好主意。戴尔就采用了这种方式,并没有完全改变Latitude E7450的设计,但相对前作E7440在许多方面有了小改进。

许多优化都只有在你把这两款设备放在一起比较时才能察觉到。它的机身比之前薄了一点点,而尽管重量相同电池的容量却增加了。在负载下的风扇噪音获得了进一步的减弱,同时处理器和显卡的性能由于采用全新Broadwell芯片而有了提升。它采用了与前作相似的高质量输入设备和一块非常出色的全高清屏幕,给人以非常全面的整体印象,我们的最终评分为88%——非常优秀。

ThinkPad T440s尽管部件较旧却多得到了两分,主要源于一些小细节,如可选的96瓦时电池,或相对更低的噪音。不过这也证明了Haswell架构笔记本电脑在2015年也不至于过时。在同样价位下新一代产品当然更物有所值,但许多已经停产的型号如Latitude E7440在未来几周内可能会有更低更诱人的售价。这也是我们对E7450有所不满的一点:在一月底近1600欧元(约11426人民币)的售价对于一台搭配Core i5处理器和128GB固态硬盘的笔记本来说有些过高。不过,即将上市的ThinkPad T450s和EliteBook 840 G2的价位应该也会非常接近——这也是由于现在欧元较弱的汇率所致。
