A desktop experience that draws you in and keeps you there. This is the idea behind today's iMac. And now that idea is more powerful than ever. The new iMac is packed with all-new processors, the latest graphics technologies, innovative storage and higher-bandwidth connectivity. And it all comes to life on the brightest and most colourful Retina display iMac has ever seen. So you get an even more immersive experience — and a scintillating new way to take it all in.

Performance

Think fast. It does.


Performance boosts across the board.

Faster and more powerful than ever, iMac is now equipped with seventh-generation Intel Core i5 and i7 processors and the latest high-performance graphics. Storage kicks into high gear as well, with the speedy and spacious Fusion Drive now available in standard configurations of both the 27-inch and 21.5-inch Retina models. So you can do everything you love to do on iMac. All at maximum velocity.

Graphics that render you speechless.

iMac features powerful new Radeon Pro 500 series graphics that make a spectacle of everything you see. 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.

Accelerate your every move.

An all-new seventh-generation Intel Core processor in every iMac. It's more speed than iMac has ever reached before — taking the 27-inch model up to 4.2GHz, and the 21.5-inch model up to 3.6GHz. And Turbo Boost gives you even more power when you're using processor-intensive applications like Logic Pro or Final Cut Pro. It all takes place behind the scenes, but you'll see the difference in so many ways.

Storage that's lightning fast. And whip 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. And it's now standard on all 27-inch models, and on the top configuration of the 21.5-inch model.

Retina Display

Retina at its most brilliant.


Brighter than ever. More colours than ever.

The Retina display shines even more vividly on the new iMac. With one billion colours and 500 nits of brightness, graphics leap off the screen in a whole new light. And the pixel density is so high that you won’t detect a single one. Text is so clear and sharp, your email and documents will look smarter than ever. It's simply the best Mac Retina display yet.

The colour you shoot is the colour you see.

The world is full of spectacular colours, and iMac brings more of them to your screen. The Retina display uses P3 colour that shifts away from standard white LEDs to advanced red/green phosphor LEDs. So all three colours — red, green and blue — are more equally represented and show off real-world colour with more balance and precision.

Connectivity

Thunderbolt 3.
Make some powerful new connections.

Double the speed and bandwidth
of the previous generation.


Two Thunderbolt 3 (USB-C) ports come standard on all iMac models, each delivering up to 40 Gbps data transfer for external drives and cameras and twice the bandwidth for video and display connectivity. Four USB 3 ports give you plenty of options for connecting peripherals, including your printer, iPhone, thumb drive and more. And with ultra-fast three-stream Wi-Fi and Bluetooth 4.2 wireless technology, you’re instantly connected to all your favourite content.

Design

A lot can happen in
5 millimetres.


Iconic design. Advanced engineering. Talk about modern art.

iMac has always been the ultimate in form and function: an all-in-one computer that puts everything — display, processor, graphics, storage, memory and more — inside one simple, stylish enclosure. The new iMac includes the most advanced, most brilliant desktop display Apple has ever built, and it’s filled with all-new technologies that take power and performance to a whole new level. Yet it’s still just 5 millimetres thin at its edge.
