Radeon Pro Duo

The Radeon Pro Duo design is simple. The engineers took two Fiji XT chips and soldered them onto a single printed circuit board. The graphics processors communicate with each other via a PLX bridge and CrossFire technology. Each GPU four stacks of the latest first-generation HBM memory with a capacity of 4 GB are attached. In addition to a pair of Fiji XT and a PLX bridge, each block has seven power phases. The Radeon Pro Duo uses chips from the Radeon R9 Nano, since the total maximum consumption of the video card is 350 W. To operate, three 8-pin connectors must be connected to the device.

Externally, the Radeon Pro Duo resembles the Radeon R9 Fury X. The design is the same, the structural elements are similar. Uses a maintenance-free Cooler Master water cooling system with two water blocks. A thick (64 mm including fan) single-section radiator is directly responsible for heat removal.
