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. 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. With four channels of memory, iMac Pro can accommodate up to 128GB. So you can visualise, simulate and render huge 3D models. Create multiple test environments for cross-platform development. And keep numerous apps open at the same time. It's all powerful. For all the things you want to do. Introducing the Apple T2 chip, our second-generation custom Mac silicon. By redesigning and integrating several controllers found in other Mac systems - like the system management controller, image signal processor, audio controller and SSD controller - T2 delivers new capabilities to the Mac. For instance, the T2 image signal processor works with the FaceTime HD camera to enable enhanced tone mapping, improved exposure control, and face detection-based auto exposure and auto white balance. T2 also makes iMac Pro even more secure, thanks to a Secure Enclave coprocessor that provides the foundation for new encrypted storage and secure boot capabilities. The data on your SSD is encrypted using dedicated AES hardware with no effect on the SSD's performance, while keeping the Intel Xeon processor free for your compute tasks. And secure boot ensures that the lowest levels of software aren't tampered with and that only operating system software trusted by Apple loads at startup.
