About this iPhone
This device is a BTO/CTO device which is nearly identical to MQ2Y2LL/A. We have listed this device separately as it has been configured with an upgraded processor when compared to the base model. This has been done to make it easier to catalog as well as easier to read.
The iMac Pro is exactly what it sounds like. Based on the iMac shape, the iMac Pro is the answer to professionals who needed more processing power but enjoyed working off the all-in-one device. This iMac Pro features a 5K Retina display and is run by a powerful Intel Xeon W processor (W-2191B) with eighteen independent processors “cores” on a single chip. The base model features 32 GB of RAM and a 1 TB SDD. The graphics behind this model are powered by a Radeon Pro Vega 56 graphics processor with 8 GB of dedicated HBM2 video memory.
This iMac Pro does not have color options like other Apple products and only comes in Space Gray. The all-in-one design features four USB-C 3.0 ports as well as connectivity via Ethernet, Bluetooth, and Wi-Fi. The only main limitation of this Pro model is how difficult it is to upgrade. It is likely that most users will need to spec their systems out at purchase with future requirements in mind.
