XFX Radeon RX 5600 XT THICC II PRO STAGING
XFX decided to join ASRock in a leaking contest. Their website already lists the yet unreleased Radeon RX 5600 XT graphic card.
The Radeon RX 5600 XT is part of the THICC series. The manufacturer figured out that the name was not confusing enough, hence it is officially called THICC II PRO STAGING.
This model carries the same cooler design as RX 5500 XT THICC II PRO kept in black and copper color scheme. It appears that the card is factory-overclocked to 1460 MHz in game mode (default is around 1400 to 1420 MHz).
The company confirmed that RX 5600 XT features 2304 Stream Processors and 6GB GDDR6 192-bit memory configuration.
