The power is in the details.

It’s amazing that so many pixels fit inside an all-in-one that’s just 5 mm at its edge. But it’s even more amazing when you consider all the power packed into iMac with Retina 5K display.

Performance right to the core.

Fourth-generation Intel Core processors.

With a quad-core Intel Core i5 processor at up to 3.5GHz — and up to 4.0GHz with the Intel Core i7 processor — this is the fastest iMac yet. And since OS X is designed to take advantage of each core, iMac captures every bit of performance from the processor.

Turbo Boost 2.0, which comes standard on iMac with Retina 5K display, gives you an automatic increase in speed when you’re using a processor-intensive application like Logic Pro or Final Cut Pro. And by shifting core frequency in small increments, Turbo Boost allows the processor to manage performance without sacrificing efficiency. All this takes place behind the scenes, so your work — and play — goes smoother and faster.

Up to 4GHz Core i7 processor

Visually astounding power.

The latest AMD graphics.

All the pixels in the world won’t do you any good if you can’t quickly and efficiently command them into action. That’s why iMac with Retina 5K display features the latest AMD high-performance graphics — with up to 3.5 teraflops of graphics compute power. So you experience stunning motion graphics, jaw-dropping visual effects, and 3D graphics so true to life that you’ll feel like you’re part of the action.

High capacity. In a flash.

Fusion Drive.

Fusion Drive is a breakthrough concept that combines the high storage capacity of a traditional hard drive with the high performance of flash storage. With Fusion Drive in your iMac with Retina 5K display, disk-intensive tasks — from booting up to launching apps to importing high-definition photos and video — are faster and more efficient. That’s because frequently used items are kept at the ready on speedy flash storage, while infrequently accessed items go to the hard drive. The file transfers take place in the background, so you won’t even notice.

For maximum performance, you can configure iMac with Retina 5K display with a 1TB or 3TB Fusion Drive with up to 1TB of flash storage.1

Twice as fast. Just as versatile.

Thunderbolt 2.

The ultimate all-in-one demands the most advanced I/O technology. Each tiny Thunderbolt port lets you expand the capabilities of your Mac. Connect high-performance peripherals. Transfer data at high speed. Even daisy-chain multiple devices. And iMac with Retina 5K display has Thunderbolt 2, delivering twice the bandwidth — up to 20 Gbps — for the fastest data transfers yet.

The next generation of wireless.

802.11ac Wi-Fi.

With three-stream 802.11ac technology, iMac takes desktop Wi‑Fi speeds over the top. When it’s connected to an 802.11ac base station — including AirPort Extreme and AirPort Time Capsule — you can reach data rates of up to 1.3 Gbps.2 That’s triple the previous 802.11n standard, which means you’ll get up to three times faster Wi‑Fi.3 You also get double the channel bandwidth, with 80MHz‑wide channels providing more room for more data to flow faster than ever.
