24寸配酷睿2大行其道 苹果iMac电脑评测(7)

    系统性能测试

    测试时我们安装了Windows Vista Home 操作系统,先来看Vista自带的Windows体验索引的评分,内存项得到了最低分4.5,其它项目得分均在5分以上。iMac配备了ATI HD2600Pro显卡,显卡性能比较强劲,因此显卡不会成为系统的瓶颈,内存项成绩偏低主要是由于容量只有1GB,而且没有组建双通道,实际上这个弱项比较好弥补,只要再加装一根1GB内存就会有立竿见影的效果。

  24寸配酷睿2大行其道 苹果iMac电脑评测

    iMac采用的是笔记本配件和台式机配件混合搭配的方式,芯片组是移动版GM965 + ICH8-ME,CPU是移动版的酷睿2 T7700,内存是移动版的1GB DDR2 667MHz,硬盘则是3.5寸的320G 7200RPM SATA,这样的搭配很明显是为了兼顾性能和功耗,不过从实际测试情况来看,磁盘性能有些偏低,不是太令人满意,看来ICH8-ME和3.5寸320G 7200RPM SATA搭配在性能上的表现还是有待改进。CPU和显卡都是比较顶级的产品,因此在性能上也有很好的表现,这也丝毫无愧于16488元的报价。
