    自从见到她 我就兴奋了

     


    说实话之前我对Acer的本本并没有好感,外型简陋身材笨拙一点没有时尚感,但是Acer新出的Timeline 3810改变了我的想法。它是今年新推出的基于Intel CULV处理器的轻薄笔记本。CULV,全称Consumer Ultra Low Voltage,译为消费级超低电压。CULV处理器定位即是入门级的超轻薄笔记本,性能和定位比都比面向上网本的Atom处理器高出很多。按照Intel的布局,CULV主要面向11到14寸的轻薄笔记本,而Atom则面向10寸以下上网本。

    Atom上网本其实是个很尴尬的产物,一方面Intel用了很多功夫把芯片体积和耗电量做到前所未有的低,另一方面太多的节俭导致了处理器结构的效率低下。这里简单的比较下Intel笔记本处理器的功耗区别:

    性能级T系列   功耗为35W(也就是我Macbook Pro里用的2.6G的C2D)
    主流级P系列   功耗为25W
    低电压L系列   功耗为15W(Macbook Air就用的这个)
    超低功耗Atom系列  2.5W

    Atom由于过度考虑省电而导致性能与上一级的L系列差距太大,而且亦只有单核版本。Intel于是推出了今天讨论的主角CULV系列超低电压处理器U系列。U系列在保留迅驰2构架的同时把耗电量和封装体积做到了最小,单核仅耗电5.5W,双核也只有10W。

    而让我最兴奋的是U系列体现出来的强劲性能,根据网友的评测,U系列处理器在性能方面相比Atom处理器几乎提高了一倍,大大缩小了和主流笔记本处理器的性能,而且新配的显示芯片GMA 4500MHD更是大大超越上网本里常见的GMA 950。最重要的是,Acer这款13.3寸轻薄笔记本实现了9小时的使用时间!这对我是最吸引的消息,因为我前段时间卖掉HP Mini上网本的最主要原因就是不满意它的电池表现。现在CULV笔记本提高了接近2倍的性能还把电池寿命大大延长到9个小时!我非常心动!
