GPU-AMD Radeon Pro Vega 56 with 8 GB GDDR5 VRAM
Featuring a 3.2 GHz Intel Xeon W 8-core processor and 32GB of 2666 MHz DDR4 ECC RAM, the iMac Pro is designed to handle demanding pro workflows, such as pro photo work, pro video editing, advanced graphics editing, virtual reality content creation, and real-time 3D rendering. The iMac Pro also has 1TB of all-flash storage, which has a 3.3 Gb/s read speed and a 2.8 Gb/s write speed, for loading huge files and launching apps faster.
In addition to a workstation-class processor, the iMac Pro also provides workstation-class graphics, thanks to the dedicated AMD Radeon Pro Vega 56 graphics card. With up to 8GB of HBM2 (High Performance Memory) VRAM and a 400 MB/s memory bandwidth, the Radeon Pro Vega 56 GPU delivers up to 11 teraflops of single precision and up to 22 teraflops of half precision.
Still just 5mm at its edge, the iMac Pro features the 27" Retina 5K display with a 5120 x 2880 resolution and a 16:9 aspect ratio. With up to 500 nits of brightness, a P3 wide color gamut, and support for one billion colors, the Retina 5K display delivers a vivid, true-to-life viewing experience.
The iMac Pro features a 10Gb Ethernet port, which is up to 10 times faster than the 10/100/1000 Mbps Gigabit Ethernet port found on the previous generation iMacs. The 10Gb Ethernet port also supports Nbase-T industry-standard 1Gb, 2.5Gb, and 5Gb link speeds. If you would rather go wireless, you can utilize the dual-band 802.11ac Wi-Fi. The iMac Pro also has Bluetooth 4.2 technology, as well as a UHS-II SDXC media card slot, four 40 Gb/s Thunderbolt 3 ports, four USB 3.0 Type-A ports, and a FaceTime Full HD camera. There is also the Apple T2 chip. The installed operating system is macOS High Sierra.
The T2 chip is Apple's 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 — the T2 chip delivers enhanced capabilities to the iMac Pro. The T2 chip image signal processor can work with the FaceTime Full HD camera to enable enhanced tone mapping, improved exposure control, and face detection-based auto exposure and auto white balance. The T2 chip also makes the iMac Pro more secure, thanks to a Secure Enclave coprocessor that provides the foundation for 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 W processor free for your workflow. 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.
The iMac Pro puts the power of a workstation into a sleek enclosure that is just 5mm wide at its edge. The all-in-one computer is powered by a single cable, which keeps your workspace clean and clutter-free. In order to keep the thin design, Apple redesigned the thermal management system in the iMac Pro. The result was an almost 75% increase in airflow and an 80% increase in system thermal capacity. Which means the iMac Pro can handle 500 watts of power — 67% more power than the previous generation 27" iMac.
