Apple weds high-res 5K visuals into its sleek, 5mm thin, mid 2017 27" iMac with Retina 5K Display. With a 5120 x 2880 screen resolution, this iMac provides 1 billion colors and 500 nits of brightness, which is 43% brighter than the previous model. The Retina 5K display also features a wider color gamut. Using a P3-based color gamut, the Retina 5K display provides a larger color space that more equally represents red, green, and blue, as compared to standard sRGB displays. And with more available colors, the images will appear more vivid and reveal greater detail, with more balance and precision.
The iMac's processor has been upgraded and now houses a 8th-gen 3.1 GHz Intel Core i5 Six-Core processor that can be overclocked up to 4.1 GHz, as well as 8GB of 2400 MHz DDR4 RAM. Visuals are powered by a dedicated AMD Radeon Pro 575 graphics card with 4GB of vRAM, and for storage, there is a 1TB FD.
Outfitted with 802.11ac Wi-Fi and backwards compatible with 802.11a/b/g/n for speedy hook-ups to your home network, this iMac is also configured with Bluetooth 4.2, as well as a UHS-II SDXC card slot, two 40 Gb/s Thunderbolt 3 ports, four 5 Gb/s USB 3.0 Type-A ports, a Gigabit Ethernet jack, and a FaceTime HD camera. It also has a Kensington lock slot for added security.
Apple's 27" iMac with Retina 5K Display (Mid 2017) operates using 100-240 VAC at 50-60 Hz and includes an Apple Magic Keyboard, an Apple Magic Mouse 2, a Lightning to USB cable, and a power cord. The installed operating system is macOS High Sierra, and protection is provided by a limited 1-year warranty, which can be extended using AppleCare.
