The iMac with Retina 5K display maintains its 5mm profile, which is up to 40 percent less volume than the 2011 iMac. Using an advanced welding method called friction-stir welding, Apple was able to join the front and the back of the iMac together directly.
802.11ac Wi-Fi & Bluetooth 4.0
With three-stream 802.11ac technology, the iMac takes desktop Wi-Fi speeds over the top. When it's connected to an 802.11ac base station - including AirPort Extreme and AirPort Time Capsule (both sold separately) - 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. Bluetooth 4.0 wireless technology is also built in, so you can connect accessories such as a wireless keyboard and mouse.
Expand the capabilities of your Mac. Connect high-performance peripherals. Transfer data at high speed. Even daisy-chain multiple devices. And the iMac with Retina 5K display has Thunderbolt 2, delivering twice the bandwidth - up to 20 Gbps - for fast data transfers. While the Thunderbolt 2 ports double as mini DisplayPorts, the iMac with Retina 5K display cannot be used as a standalone monitor like its predecessor. It can, however, be used simultaneously with an external display and can output up to a 5120 x 2880 resolution.
With USB 3.0, you can transfer large files in seconds instead of minutes. Every iMac comes with four USB 3.0 ports - with speeds up to 10 times faster than USB 2.0 - and you can connect all your USB-compatible devices, including your iPhone, iPad, iPod or digital camera.
