MRT42LL/A-Dist Sourcing
Pretty. Freaking powerful.
The vision behind iMac has never wavered: Transform the desktop experience by fitting powerful, easy-to-use technology into an elegant, all-in-one design. The new iMac takes that idea to the next level - giving you even more amazing tools to do just about anything. iMac is packed with the latest processors, faster memory, and phenomenal graphics. All coming to life on the brightest, most vibrant Retina display ever on a Mac. It's the total package - powered up.
Retina Display
Show-stopping.
Eye-popping.
So bright and colorful, you can't look away.
Available in stunning 4K or 5K, the Retina display shines beautifully on iMac. With one billion colors and 500 nits of brightness, graphics leap off the screen. Text is razor-sharp. Binge-worthy shows and blockbuster movies have never looked more amazing. Graphics and games dazzle in exquisite detail. It's simply the best Mac Retina display yet.
Amazingly true-to-life color.
The world is full of spectacular colors, and iMac brings more of them to your screen. The Retina display uses P3 color that shifts away from standard white LEDs to advanced red-green phosphor LEDs. That means all three colors - red, green, and blue - are more equally represented and show off real-world color with more balance and precision, bringing all your photos and content to life more vividly.
Performance
Quite the power couple.
Speed. From blazing to breakneck.
Faster than ever, iMac is now equipped with eighth- and ninth-generation Intel Core processors and the latest in high-performance graphics options. Storage zips along too, with the snappy and spacious Fusion Drive available in both models. Or you can configure iMac with up to a 2TB SSD. So no matter what you're into, you can do anything you love on iMac. All at maximum velocity.
Up to a whopping 8 cores. Process that.
With ultrapowerful quad-core and all-new 6- and 8-core processors, iMac is a total tour de force. The 27-inch model now clocks Turbo Boost speeds up to 5.0GHz, and the 21.5-inch model reaches 4.6GHz. Which means you get more muscle when you're using processor-intensive applications like Logic Pro X or Adobe Photoshop. Everything feels flat-out fast.
Graphics that render you speechless.
iMac features robust new Radeon Pro 500X series graphics that make everything you see even more extraordinary. The 27-inch iMac with Retina 5K display is loaded with up to 8GB of dedicated VRAM. And the 21.5-inch iMac with Retina 4K display ignites with up to 4GB. Both deliver visual effects and 3D graphics that exhibit raw power in its most polished form.
