联想 Z51-70 (Radeon R9 M375) 笔记本电脑简短评测

Name: Lenovo Z51-70
Brand: Lenovo

五味杂陈。 联想的这款新产品希望凭借中端显卡在多媒体产品中一展身手，不过它的屏幕和音响效果拖了后腿。它的键盘也可能会让需要用它来办公的用户失望。不过，它的其它方面，特别是性能，都十分出色。

- 最多算是一般的键盘

- 暗淡，可视角度窄的TN屏幕

- 音响系统明显有瑕疵

In review: Lenovo Z51-70. Test model courtesy of Cyberport.

联想承诺过的IPS屏幕在哪儿呢？不管怎么说，它都会给我们的测试机带来很大改观。结果我们不得不忍受一块磨砂的平庸TN技术屏幕，它的可视角度范围十分有限且色彩还原也需要改善。当然质量较差的键盘和较弱的可维护性也是值得一提的缺点。一些小的工艺瑕疵并不影响它机身设计的整体成功，特别是对于一台多媒体笔记本电脑来说。不过，音响系统的明显瑕疵给我们的测试编辑在评分时带来了不小的麻烦，因为我们不能为它减少一个评分点。

与此形成反差的是它的技术层面，强劲的处理器和高速固态硬盘提供了流畅的使用体验，这也是它的优势所在。

它的触控版十分优秀。最近一段时间表现欠佳的AMD也带来了令人满意的表现：Z51系列中所采用的最强的一款显卡是全新的Radeon R9 M375，它可以与同价位显卡如Nvidia GeForce 940M相竞争。我们不建议用户购买搭配较弱显卡的型号，因为它们已经进入了商务笔记本电脑的范围，而它的键盘却很难让人满意。
