Apple iMac(27inch Retina 5K Display, 1TB, 8GB, 3.3GHz Intel Core i5 Quad Core, MF885)(Mid 2015)
Apple weds stunning 5K graphic visuals into their sleek 5mm thin design aesthetic with their 27" iMac with Retina 5K Display released in late 2014. With a 5120 x 2880 native resolution, the graphics on this iMac are clearer and more eye-catching than on any other previous model.
Apple also features a quad-core 4th-gen Haswell 3.3 GHz Intel Core i5 processor into the mix, along with 8GB of 1600 MHz DDR3 RAM. The four SO-DIMM slots are user accessible, so you have the option to upgrade the RAM up to 32GB for higher-end video or photo production needs.
To aid you in that endeavor, this late 2014 iMac is also equipped with a 1TB 7200 rpm Hard Drive. Boot times are greatly reduced, resulting in a faster, smoother user experience.
To help with the enhanced display, this iMac also includes an AMD Radeon R9 M290 graphics card with 2GB of GDDR5 memory. This powerful GPU was designed for high-level gaming, but will do double duty when editing videos or large resolution photos.
Other amenities include an integrated FaceTime HD camera, dual microphones, stereo speakers, a full-size keyboard with 78 keys, including 12 function keys and 4 arrow keys (inverted "T" arrangement), and a Magic Mouse.
Outfitted with 802.11ac Wi-Fi (backwards compatible with 802.11a/b/g/n) for the speediest hook-ups to your home network, this iMac is also configured with Bluetooth 4.0, as well as an SDXC card slot for extra storage, four USB 3.0 ports, two Thunderbolt 2 ports, and a Gigabit Ethernet (RJ-45) jack. It also has a Kensington lock slot for added security.
The 27" iMac with Retina 5K Display runs on the Mac OS X Yosemite operating system. Yosemite has been designed to take advantage of high-end displays, and to integrate iOS devices and your desktop Macs with ease. It also improves almost every area of the Mac OS X, including but not limited to, Safari, Finder, AirDrop and FaceTime, to name a few.
For ports, the iMac has dual Thunderbolt 2 ports (which also double as Mini DisplayPorts) and four USB 3.0 ports. You'll be able to connect with various compatible components. If you would rather go wireless with your peripherals, you can use Bluetooth 4.0 technology where compatible.
27" Retina 5K IPS Display
Whether your iMac is in your studio, living room, or kitchen, the display is the focal point. With a 5120 x 2880 resolution, the iMac with Retina 5K display features 14.7 million pixels, which allows for crisp, clear text and support for 4K photos and videos. The IPS panel allows for wider viewing angles so more people can enjoy the Retina 5K display without having to crowd around it.
AMD Radeon M290 Graphics
All the pixels in the world won't do you any good if you can't quickly and efficiently command them into action. That's why the iMac with Retina 5K display features a dedicated AMD Radeon M290 graphics card with up to 3.5 teraflops of graphics compute power. So you experience stunning motion graphics, jaw-dropping visual effects, and 3D graphics on the built-in Retina 5K display.
4th Generation Haswell Intel Core i5 Processor
The iMac houses a quad-core 4th-gen Haswell Intel Core i5 processor. Its quad cores can reach a stock speed of 3.3 GHz. It can also be overclocked up to 3.7 GHz, thanks to Intel Turbo Boost 2.0 technology. The 4th-gen Haswell Intel processor uses low voltage for better energy efficiency while still providing fast performance.
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 and 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 3840 by 2160 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.
Mac OS X Yosemite
The iMac with Retina 5K display ships with the Mac OS X 10.10 Yosemite operating system. With a redesigned interface, Apple continued their integration between Mac OS X and iOS devices. Relying on iCloud and your Apple ID, both Mac OS X Yosemite and iOS 8 work together to ensure you can switch seamlessly from your iPhone or iPad to your iMac with Retina 5K display.
