Power to the pro.
Pros love iMac. So we created one just for you. It’s packed with the most powerful graphics and processors ever in a Mac, along with the most advanced storage, memory, and I/O — all behind a breathtaking Retina 5K display in a sleek, all-in-one design. For everyone from photographers to video editors to 3D animators to musicians to software developers to scientists, iMac Pro is ready to turn your biggest ideas into your greatest work.
Up to 18 cores in an iMac. No, that’s not a typo.
An iMac with 4 cores is remarkable enough. But an iMac with 8, 10, 14, or 18 cores is an entirely different creature. Add Turbo Boost speeds up to 4.5GHz, and iMac Pro has the power and flexibility to balance multicore processing with single-thread performance. With new AVX-512 vector instructions and a new cache architecture, the processor handles even more data — even more quickly. Which means you can render images, edit up to 8K video, manipulate photos, create real-time audio effects, or compile your next five-star app — all at lightning speed.
Particle simulation? Elementary.
Billowing smoke. Torrential rain. A wheat field in the wind. With up to 18 cores and Hyper-Threading, iMac Pro lets you build and render particle systems of all kinds — static or animated, 2D or 3D — with ease.
Vega graphics. The beast behind the beauty.
Featuring Radeon Pro Vega graphics, iMac Pro delivers the best workstation-class graphics of any Mac. The first Mac with Vega architecture features up to 16GB of High Bandwidth Memory, which helps deliver a major jump in performance — up to two times faster than any other iMac GPU and up to three times faster than the GPU in Mac Pro. This translates to higher frame rates for VR, real-time 3D rendering, more lifelike special effects, and gameplay at max settings. It also supports both single- and half-precision computing, so operations that don’t require a full 32 bits of precision can be performed twice as fast. How fast? Up to 22 teraflops fast.
