802.11ac Wi-Fi. The new definition of fast.
With three-stream 802.11ac technology, iMac takes desktop Wi-Fi speeds over the top. When it's connected to an 802.11ac base station - including the new AirPort Extreme and AirPort Time Capsule - you can reach data rates of up to 1.3 Gbps. That's triple the previous 802.11n standard, which means you'll get up to three times faster Wi-Fi. You also get double the channel bandwidth, with 80MHz-wide channels providing more room for more data to flow faster than ever. Thunderbolt I/O. It's all about speed and versatility. And speed.
With one tiny port, you get superfast data transfer speeds and huge expansion capabilities. Thunderbolt features two 10-Gbps data channels per port, which means data transfer is up to twice as fast as USB 3 and up to 12 times faster than FireWire 800. And don't worry about a single drive or peripheral tying up a Thunderbolt port: You can daisy-chain as many as six devices plus a display. All iMac models include two Thunderbolt ports for even more expansion possibilities. FaceTime HD camera for high-resolution video calls.
Get everyone in the picture with crisp, widescreen HD video. The built-in 720p FaceTime HD camera lets you make video calls that are so clear, it seems like everyone's in the same room. Make FaceTime calls from your iMac to any FaceTime-enabled Mac, iPhone, iPad, or iPod touch. The ultimate all-in-one. Honed to the cutting edge.
The first iMac was a revolution: An all-in-one computer that put everything - display, processor, graphics, storage, memory, and more - inside one simple, stylish enclosure. Countless innovations later, we've raised the bar yet again. The new iMac includes the most advanced, most brilliant desktop display we've ever built, and it's filled with the latest high-performance technologies. Yet it's just 5 mm thin at its edge with up to 40 percent less volume than the previous generation. To do all that required unprecedented feats of engineering - and imagination. We invented new technologies, pioneered new manufacturing techniques, and devised all-new ways to do more in less space. 75 percent less reflection.
Full lamination has a second major benefit: It eliminates the reflection of light off the LCD panel and off the back of the display's cover glass. But we also figured out how to reduce reflection off the front of the glass without compromising color quality. Instead of applying an antireflective coating to the glass in a conventional way, we adapted a process used on smaller surfaces like camera lenses and fighter pilots' helmets. It's called plasma deposition, and it involves coating the glass with layers of silicon dioxide and niobium pentoxide so precise and so thin they're measured in atoms. The result: an astounding 75 percent reduction in reflectivity - and vibrant, accurate colors. Mac OS X
