Apple iMac Pro 27-inch 2.5 GHz 14-Core Xeon W-2170B 64GB RAM 2TB SSD Storage Radeon Pro Vega 56 Graphic 5120 x 2880 MHLV3LL/A-BTO A1862

Apple iMac Pro "14-Core" 2.5 27-Inch (5K, Late 2017)
The iMac Pro "14-Core" 2.5 27-Inch (5K, Late 2017) technically is a "configure-to-order" configuration of the iMac Pro "8-Core" 3.2 27-Inch (5K, Late 2017) -- or starting August 4, 2020 -- the iMac Pro "10-Core" 3.0 27-Inch (5K, Late 2017), but also is documented as a separate model for reader convenience. Other than processors (and the corresponding cache), this model can be configured identically to its stock counterpart.

The iMac Pro "14-Core" 2.5 27-Inch (5K, Late 2017) features a 2.5 GHz Intel Xeon W processor (W-2170B) with fourteen independent processor "cores" on a single chip, 33.25 MB of cache, 32 GB of difficult to upgrade 2666 MHz DDR4 ECC SDRAM, a 1 TB SSD, and an Radeon Pro Vega 56 graphics processor with 8 GB of dedicated HBM2 video memory. It also has a built-in 1080p "FaceTime HD" webcam, stereo speakers, four microphones, and a 27" 5120x2880 LED-backlit 16:9 widescreen IPS DCI-P3 "Retina 5K" display, all packed in a thin, dark "Space Gray" housing.

Connectivity includes four USB 3.0 ports, four Thunderbolt 3 (USB-C) ports, Nbase-T Ethernet, 802.11 ac Wi-Fi, and Bluetooth 4.2.

Compared to the "regular" 27-Inch iMac models that this iMac Pro complements, the iMac Pro not only has a dark "Space Gray" housing, but also has a much faster and more advanced architecture and graphics architecture as well as faster memory and storage and additional connectivity, but is much more difficult to upgrade, an unfortunate -- and unnecessary -- limitation for a "professional" system.
