iMac 21.5" (Retina 4K, March 2019) The all-in-one for all. If you can dream it, you can do it on iMac. It’s beautifully designed, incredibly intuitive, and packed with powerful tools that let you take any idea to the next level. And the new 27-inch model elevates the experience in every way, with faster processors and graphics, expanded memory and storage, enhanced audio and video capabilities, and an even more stunning Retina 5K display. It’s the desktop that does it all — better and faster than ever. Draws you in. Blows you away. Everything looks better on a Retina display, with its one billion colors and 500 nits of brightness. Photos and graphics leap off the screen. Text is supersharp. And for the first time, the 27‑inch iMac features True Tone technology for a more natural viewing experience and a nano-texture glass option to reduce glare to the barest minimum. Nano-Texture Glass Minimum glare. Maximum detail. First seen on the Pro Display XDR, the nano-texture glass option on the 27‑inch iMac is a game-changer for workspaces with sunlight, direct light, or changing lighting conditions. Unlike typical matte display coatings, the nano-texture is etched into the glass at the nanometer level. This reduces glare while preserving contrast, for jaw-dropping image quality. Processor and Memory From fast to fasten your seatbelt. iMac and powerful processors go hand in hand. Up to a 6-core Intel Core i7 processor gives the 21.5‑inch iMac all the power you need for creating in Photoshop, editing video, or making music. And the 27-inch model offers up to a 10-core Intel Core i9 processor to sail through heavy tasks like layering dozens of audio tracks or compiling and testing code. More memory. For major processing. The 21.5‑inch iMac can be configured to a formidable 32GB of memory. And the 27‑inch iMac can now be configured to 128GB — double the capacity of the previous generation — to fly through the most complex pro workflows up to twice as fast. Graphics Next-level. At any level. The graphics on iMac make everything a sight to behold. The 21.5-inch model comes with AMD Radeon Pro 500X series graphics, and can be configured with an AMD Radeon Pro Vega 20 GPU to power through tasks like 3D rendering or complex video effects with ease. And the 27-inch model brings AMD Radeon Pro 5000 series graphics with up to 16GB of GDDR6 memory for graphics-intensive workflows like editing UHD video or developing lifelike game environments. Storage More space. More speed. All-flash SSD storage is now standard on all iMac models, bringing high capacity and lightning speed. And the 27‑inch iMac can now be configured up to a whopping 8TB SSD with up to 3.4GB/s sequential read and write speeds, for screaming-fast access to all of your photo and video libraries, massive files, and pro apps. Camera, Speakers, and Mics Mics, camera, action. From crystal clear video calls and voice recordings to music and movies that fill the room, iMac is an all-star for communications and content. The 27‑inch iMac now features a 1080p FaceTime HD camera and a studio-quality three-mic array. And the T2 chip acts in concert with the speakers to enable variable EQ and an enhanced bass response, so all your content can have big, balanced high-fidelity sound. Apple T2 Security Chip Your own private security detail. The Apple T2 Security Chip comes to the 27‑inch iMac, with a Secure Enclave coprocessor that provides the foundation for secure boot and encrypted storage capabilities. The T2 chip also enables powerful features like the 1080p FaceTime HD camera, face detection, enhanced speaker bass response, and “Hey Siri” — and makes transcoding HEVC video up to twice as fast as the previous generation. Connectivity Packed with ports. And possibilities. Every iMac features two superfast Thunderbolt 3 (USB-C) ports and four USB-A ports, giving you plenty of high-performance options for connecting external drives, cameras, displays, and more. All iMac models come with a 1Gb Ethernet port, and now you can configure the 27‑inch iMac with 10Gb Ethernet for up to 10 times the throughput of the previous generation. Ultrafast Wi-Fi and Bluetooth are standard on every iMac, and the 27‑inch model features Bluetooth 5.0, so you’re instantly connected to your favorite content and wireless devices.
