2009-10-16 10:13:01 IT168 发表评论
    

    通过前面的测试我们了解到,联想IdeaPad U450笔记本在核心部件的性能表现上较早期的U系列产品有着明显的提升。特别是在屏幕的选择上,体现出了联想一贯的高品质。然而,出色的用料与硬件搭配最终是要体现在综合性能的表现上,毕竟,只有均衡的性能发挥才能为用户带来高效的应用体验。

Vista体验索引测试

    目前主流的消费级笔记本电脑均开始采用Vista系统,因此联想IdeaPad U450笔记本在Vista上的表现具有重要的参考性。从Vista系统评估来看,整体最终得分为3.8,在各个子项中,显卡的性能表现成为了整套平台的瓶颈。这与联想IdeaPad U450的市场定位有着一定关系,其产品从设计到用料更多的是偏重了便携应用以及办公娱乐的需求,并不适合大型3D图形的处理工作。

    在PCMarkVantage的测试中我们同样到看其游戏性能的不足,在图形处理器方面IdeaPad U450更适合视频播放、2D渲染或是入门级的3D处理应用。从各个子项的得分来看,联想IdeaPad U450在主要核心部件的性能表现上,全面超越了先前推出的单核U350笔记本。
