Over recent weeks we have seen some odd looking graphics cards launched. I'm mainly talking about the cryptocurrency mining cards, many of which have no video outputs, making them decidedly one-trick ponies. Though there are some Nvidia GPU-based mining cards on the way to market, it looks like AMD solutions are more popular here. Now it looks like AMD and its partners are making use of any old Radeon Polaris GPU lying around and this is evidenced by various sources spotting these Radeon RX 560D and Radeon RX 470D graphics cards.
