Built for speed. And everything else.
You know iMac by its incredibly thin enclosure. But that just sets the stage for massive performance. With a new Intel Core processor, the latest AMD graphics, advanced Fusion Drive options, and Thunderbolt 2, iMac delivers lightning-fast speed. And striking power.
Think fast. We did.

You couldn’t ask for more speed. Yet Turbo Boost 2.0 gives you even more 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 performance.

The latest AMD high-performance graphics give the 27-inch iMac with Retina 5K display up to 3.7 teraflops of graphics compute power. The 21.5-inch iMac with Retina 4K display also lights up with enhanced Intel Iris Pro Graphics. Both deliver visual effects and 3D graphics that exhibit raw power in its most polished form.
A fusion of storage, speed,
Fusion Drive combines the spaciousness of a traditional hard drive with the high performance of flash storage. Choose a swift 1TB Fusion Drive or a lightning-fast version with up to 3TB of storage.1 Whatever the choice, everything from booting up to launching apps to importing photos is faster and more efficient. That’s because your frequently used items are kept at the ready on speedy flash storage, while infrequently accessed items go to the hard drive. It’s the best of both worlds.
For maximum performance, you can configure iMac with up to 1TB of PCIe-based flash storage that’s now up to 2.5 times faster than the previous version.2 Delivering up to 1800 MBps of sequential read performance, pure flash storage is the fastest way to blaze through the most demanding tasks.
Blazing-fast data transfer.
Each of the two ultrafast, ultraflexible Thunderbolt 2 ports significantly expand the capabilities of iMac. For example, you can connect high-performance peripherals and move data up to 40 times faster than with USB 2, and up to 25 times faster than with FireWire 800. You also have more than enough bandwidth — up to 20 Gbps — to daisy-chain multiple high-speed devices and still maintain maximum throughput.
Up to three times faster Wi‑Fi.
With three-stream 802.11ac technology, iMac takes desktop Wi-Fi to unprecedented speeds. Simply connect to an 802.11ac base station — such as AirPort Extreme or AirPort Time Capsule — and reach data rates of up to 1.3 Gbps.3 That’s triple the previous 802.11n standard. You also get double the channel bandwidth, with 80MHz-wide channels providing more room for more data to flow faster than ever.
