AMD and its partners quietly began selling Radeon RX 560 cards with fewer compute units and stream processors than originally advertised without changing the name or otherwise identifying the lesser-powered model in any way. The GPUs you can find in stores are a mix of the full-fat version and the cut-down version, making things much trickier. Thanks Blah Blah.



People have started to notice that graphics card vendors are shipping products labelled as RX 560 cards in configurations with 896 SPs, and others with 1024 SPs. Heise Online was the first to report the change in official specs and presence of cards in retail with fewer SPs and no obvious way to detect the difference while casually browsing.
