27-inch iMac Late 2012 开箱

文章分类 , ,
话说由于去年研究室的经费剩下太多，上个学期结束之前教授大大就问我有啥想买的设备，Zell想了半天实在是没有缺啥，年中刚自费买了，学校又发了一堆PC啥的，电脑是完全够用了。无奈研究费剩下实在太多，多到每个人都要新买一台，于是教授说要不搞台mac pro吧。Zell连忙打住，那货都两年没更新了，最后还是决定买这台超薄的imac，代替每天背着上学的RMBP。
私立大学的研究室资源确实过剩，除此之外，我又怂恿中村同学搞了台13寸的RMBP，那家伙本是个PC用户，换了mac之后连说好用。
本来打算拍一个详细的开箱测评的视频，无奈这货太大太重，研究室的状况又惨不忍睹（一群杂乱无章的IT男聚在一块是不可能整洁的起来的），还是决定不拍了。
外箱很蛋疼的做成了梯形，内部各种泡沫做缓冲，还算蛮结实的样子。
电源藏在这里里面，另外一个位置是空的。
下面是定的键盘和触摸板，触摸板手感一流，比macbook的还要大一点，非常舒服，键盘的手感就差多了，反馈和手感都不如macbook，和一些山寨键盘的手感很相似，唯一的优点就是漂亮的造型。
各处细节，下面是内存的插槽，由于apple官方的配件都是天价，这次只选了标配4Gx2的内存，另外在amazon买了4条8G的内存条，等到了再发个更换内存的小记。
顺利插入！
各种接口都在机器的后面，好看是好看，就是有点不方便，特别是桌上摆满了显示器之后，很难够得到。
书桌上一下子来了这么大个东西，原来的两台22寸的EIZO已经没法放了，好在可以竖起来假装是用来看论文什么的。
接下来就是拷贝数据了，RMBP没有网络接口，只能从研究室的公共wifi走数据，结果这一考就考了6个多小时….
基本配置如下
硬盘选购了fusion drive，也就是苹果的混合硬盘，简单测试一下连续读的能力稍逊于RMBP的SSD，连续读能力不错。可能由于fusion drive的算法导致每次测试结果都有所不同，第一次测试接近连续读取速度接近420M/s。（RMBP的SSD读写都在400M/s前后）
由于有强力的CPU和显卡，Geekbench跑分1W3，和16G +SSD的RMBP在同一水平，估计换了内存之后可以轻松超越RMBP。

简单的上手，感觉还是一台非常棒的电脑，外观无可挑剔，性能也能满足绝大部分人的需要，除了键盘手感稍差之外没有什么缺点了，在PC上apple还是甩开了其他厂商一大截的，希望下一代可以把边框做的更窄一点。
收工，谢谢观赏~

At A Glance
With the 2.66GHz Core i5 iMac (not to mention the build-to-order 2.8GHz Core i7 model), Apple has blurs the line between consumer and professional systems. The 2.66GHz Core i5 iMac offers faster performance at most tasks than the 2.66GHz Quad-Core Mac Pro. The Core i5 iMac also has more memory and more storage space than that Mac Pro, while costing $500 less. Unless you absolutely require additional PCI cards, multiple internal hard drives, or a lot of RAM, the Core i5 iMac makes a strong case for the being the go-to system for most Mac professionals.
