用新的哈斯威尔芯片imac

如果你喜欢以前的imacs的外观和表现,你也喜欢新的模型

苹果updated to its iMac line in September, adding Haswell chips, faster storage options and support for 802.11ac Wi-Fi while leaving the stylish look intact. Columnist Michael deAgonia explains what's new and what's not.

I should say this right from the start: When it comes to Apple's current line ofIMAC一体化桌面电脑, I love the design. Love, love, love it.

我一直是铝制封闭苹果的忠实粉丝,苹果在其产品线上雇用,但我非常感谢它在27型中使用。imac模特坐在我的书桌上。从黑色边界玻璃到铝“下巴”到5毫米薄锥形边缘,我崇拜imac的外观,庆幸从去年的模型中没有改变

苹果9月下旬更新了IMAC,将其移动到英特尔最新的“HASWELL”处理器,添加了更快的固态存储选项并为802.11ac Wi-Fi添加支持。由于2012型型号的价格保持不变,所有这三个变更都为买家提供了一个坚实的表演者,更好的交易。

That's usually the Apple way. Boost performance, tweak the design and keep prices intact.

现在熟悉的阵容继续如以前,入门级IMAC(屏幕21.5英寸)起价为1,299美元,更大的27英寸。型号起价为1,799美元。

我使用的模型是27英寸。版本由Apple提供,完成hybrid "Fusion" drive该公司在一年前推出了当前设计时亮相。该驱动器现在使用基于PCIe的闪存,Apple表示可以通过SATA III闪存的型号提高50%的型号。

如果你不习惯这个大的屏幕,你就是为了一种享受。它足以让您可以在不必使用空格或缩小Windows大小以创建多个开放文档而无需使用空格。当然,在与空间和Apple MultiTouch TrackPad的音乐会中,IMAC可以成为生产力推动力。

I quickly grew accustomed to the display's size. But what I could never get used to is the view from the side. Maybe it's because I grew up in a CRT world, where monitors were big, and chunky and beige, but the sides of the iMac always seem to be impossibly thin, as if the machine resides in 2D space. Sure, the back of the unit becomes progressively thicker at its center to accommodate the internal hardware, but catching a glimpse of the iMac from the side leaves me with a feeling of 'wow' every time.

Apple仅提供两种尺寸的IMAC,具有两个标准配置。但购买时有丰富的选择。重要的是要通过您需要的东西思考,因为如果您购买较小的IMAC,您将无法稍后打开并添加RAM。

配置和选项

The cheapest iMac is the 21.5-in. model. It sports a quad-core processor, Intel's 2.7GHz Core i5 (featuring a 4MB L3 cache and Turbo Boost speeds up to 3.2GHz), a 1TB hard drive and integrated Intel Iris Pro graphics. The hard drive is a 5400rpm model, which is a mediocre drive compared to the faster Fusion drive (or the super-fast, but pricey, SSD option). The Iris Pro graphics represents a decent update compared to the previous generation, but you'll still get better performance on the 1920x1080-pixel display from a discrete graphics card. That leads me to the next model.

花费200美元,你得到21.5英寸。IMAC与四核2.9GHz I5(具有6MB L3缓存和Turbo Boost速度高达3.6GHz),尽管您可以将处理器撞到3.1GHz核心I7。这款人员还配有5400rpm 1TB驱动器,尽管您可以升级到256GB或512GB闪存驱动器或1TB融合驱动器。(更多关于在一分钟内的融合驱动器。)与其他配置不同,该模型与NVIDIA GeForce GT 750M图形带有1GB的GDDR5内存 - 如果您进入游戏,则更好的选择。

21.5-in。imacs带有8GB的记忆,现在这是充足的。但是,如果您想要未来的计算机,考虑将RAM加倍至16GB(以上)。就像去年一样,这个模型没有用户可替换的内存插槽,因此如果您现在没有得到额外的内存,则无法稍后添加。就苹果而言,试图这样做可能会使您的保修失效。(IMAC使用粘合剂代替磁体以使屏幕连接到铝体上。

对于更多的电源,更大的显示器或两者,IMAC的选择是27厘米。1799美元的型号配有3.2GHz四核Intel核心I5(3.6GHz Turbo Boost和6MB的L3缓存)和NVIDIA GeForce GT 755M图形处理器,具有专用的GDDR5内存。这是从图形卡中的卷入越来越昂贵的21.5英寸。imac。

另外200美元可以让您提供一个IMAC,配备了3.4GHz四核I5,可以撞到3.5GHz四核核心I7。为最佳性能,核心I7芯片是去的方式。高端IMAC显示器使用具有2GB的GDDR5内存更强大的NVIDIA GeForce GTX 775M图形处理器,您可以使用4GB的GDDR5内存获得NVIDIA GeForce GTX 780m,如果绝对是最佳的,则可以使用4GB。

两个较大的IMAC都带有8GB的内存,可扩展到32GB。你买的时候可以最大限度地爆炸,或者稍后自己做。(与21.5英寸不同。模型,较大的IMAC在单元的后部有一个用户可维修的存储器端口,夹在支架和主体相遇的位置下方。)两者也带有1TB驱动器,虽然这些是至少7200rpm驱动器,以便在框中更好地执行性能。您可以使用3TB硬盘配置此计算机,升级到1TB或3TB Fusion Drive,或选择256GB,512GB或1TB的闪存存储。

基于闪存的存储是绝对的路要走you want the best overall performance, but it's also among the most costly options. The 256GB SSD adds $200 to the bottom line; the 512GB SSD adds $500; and if you decide to go with the 1TB option, it'll set you back an additional $1,000.

其他IMAC功能

All iMacs sport the same stylish aluminum-and-glass enclosure, and all come with a FaceTime camera for video conferencing, surpassingly strong built-in stereo speakers, and dual microphones for noise-canceling and better voice recognition when conducting video chats or dictating text.

连接选项比比皆是。在IMAC的后部是SDXC卡插槽,四个USB 3.0端口,两个Thunderbolt端口和用于连接外部监视器的迷你显示端口。支持千兆以太网 - 对于仍然依赖电线的人和无线人群,IMAC支持蓝牙4.0和新的802.11ac无线标准。耳机端口还通过Minijack支持光学音频。

如前所述,显示屏真的很华丽,甚至是照明和充满活力,色彩清爽。这几乎足以让我忘记超级高分辨率视网膜显示IMAC的可能性。几乎。

Maybe next year.

That being said, this design -- stylish as it is -- can also be extremely inconvenient. The peripheral ports are all hidden behind the huge screen, which is a pain if you're in the habit of constantly plugging and unplugging peripherals. It's nothing new, but it certainly is the trade-off for this design.

使用imac.

Setting up this iMac was a snap. I am an iCloud subscriber and I use Notes and Pages often -- both of which support iCloud sync. Logging into my iCloud account on the iMac automatically brought over all of my current documents, Finder Tags and Notes as well as other data like calendars. But my main concern was access to my in-progress articles. Clicking on my custom Work In Progress tag in the Finder sidebar showed all of my current documents, even though I never transferred the files over to the machine. Before the release of OS X Mavericks, these files would be accessible through Pages; with Mavericks, my work was right there in Finder, waiting for me.

That's almost too easy.

但是,这真的是我们对计算设备所期望的东西这些天。因为所有机器都相对响应 - 特别是在这些价格点,因此无论设备如何访问我们的内容,它并不多。Apple获得了很多热量,因为其在线服务与一些竞争对手有更多的问题,但在它工作时,它运作良好。当使用IMAC时,它对我效果很好。

至于imac本身,它总是响应于整体使用,总是晴朗,并保持完全沉默。如果您在安静的环境中运营并希望环境保持这种方式,IMAC应该适合。

毫无疑问,融合驱动器有助于保持噪音水平。请记住,Fusion Drive实际上是一个混合驱动器,具有小型SSD段和更大的部分,依赖于5400rpm硬盘驱动器。Fusion Drive使OS X感到迅速。只有当您需要访问存储在硬盘上的文件时,事情开始减慢一点。许多用户甚至不会注意到,但我做到了。这就是为什么我推荐SSD驱动器如果您可以作为一个选项,则Fusion驱动器作为后备和5400rpm的驱动器永远不会。

融合驱动器有多快?使用Blackmagic Disk Speed Test, I got results showing write speeds averaging between 260MBit/sec. and 315MBit/sec., and read speeds between 490Mbit/sec and 515MBit/sec. Those are noticeably faster speeds than you'll see with any hard drive, even the 7200rpm versions.

每当我查看Mac时,我都有一个复杂的50分钟iMovie项目,即我渲染。(imovie'11文件使用Apple的“大”设置导出,导致H.264 M4V文件,具有960×540像素分辨率。)从2010年的2.8GHz四核I5 IMAC呈现了电影项目一个小时和八分钟;我去年测试的imac在48分钟内完成了。最新的imac是...... 5秒比这更快。

换句话说,今年的IMAC几乎与去年一样快。

最后一个注意:作为OS X成熟,它的多点触控支持也是如此。考虑到这一点,我强烈推荐使用AppleMagic Trackpad($69) with the iMac instead of the included Magic Mouse. It puts the massive screen literally at your fingerprints, allowing you to swipe with ease through documents, photos and apps and navigate quickly through virtual desktops. It really will boost your productivity.

At $1999, this iMac isn't inexpensive, but wow, is it a stunner, even at that price. If there's a better all-in-one computer around, it would have to be the 27-in. iMac with the Intel Core i7 chipset. With 32GB of RAM. And a 1TB SSD for storage. Of course, that one will cost $3,799.

对于更多主流用户,1,999美元的版本应该很好。这是真实的,这是你的第一个IMAC,还是你只是希望在去年的大型改变之前升级IMAC购买。目前的阵容应该在未来几年内为您服务。

My verdict on the 2013 iMac: Recommended.
