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.
So bright and colourful, you can’t look away.
Available in stunning 4K or 5K, the Retina display shines beautifully on iMac. With 1 billion colours and 500 nits of brightness, graphics leap off the screen. Text is razor-sharp. Binge-worthy programmes and blockbuster films have never looked more amazing. Graphics and games dazzle in exquisite detail. It’s simply the best Mac Retina display yet.
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 ultra-powerful 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, while 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.
Bump it up to beast mode with Vega.
For even greater graphics performance, Radeon Pro Vega GPU options are now available on iMac. Vega — the same graphics architecture found in iMac Pro — delivers an enhanced compute engine and utilises High Bandwidth Memory (HBM2). This doubles the memory bandwidth to the GPU, resulting in sizzling performance. And it allows iMac to tackle graphics-intensive tasks like 3D rendering or complex video effects in a whole new — and much faster — way.
Storage that’s lightning fast.
And super smart.
Storage is about space. But it’s also about speed. A Fusion Drive gives you the best of both worlds. The apps and files you use the most are automatically stored on fast flash storage, while everything else moves to a high-capacity hard drive. From booting up to launching apps to importing photos, it’s faster and more efficient to do it all with Fusion Drive. It comes as standard on all 27-inch models, and as an option on the 21.5-inch model.
iMac + macOS
macOS is the operating system that powers everything you do on a Mac. It lets you do things you simply can’t do with other computers. That’s because it’s designed specifically for the hardware it runs on — and vice versa. And the latest version, macOS Catalina, gives you more of everything you love about Mac.
iMac + iPhone
Your iMac works seamlessly with your iPhone. So whether you’re texting, snapping a photo, or copying and pasting an image, you can move between devices without missing a beat.
