The Radeon RX 6000 series will be made up of at least three GPUs called Sienna Cichlid, Navy Flounder and Dimgrey Cavefish. Dimgrey Cavefish will be the baby of the series and will be based on AMD's GFX103X graphics architecture. The Radeon RX 6000 series will go live on October 28.

AMD may be unveiling the Radeon RX 6000 series next month, but details about upcoming RDNA 2 cards have been revealed by the developers of ROCm Developer Tools, as we reported earlier this week. Now, Videocardz has deduced more information from the data was posted.

According to Videocardz, Navy Flounder is Navi 22 while Navi 23 is Dimgrey Cavefish. The ROCm Developer Tools team clarify that AMD has randomly assigned the names Navy Flounder and Dimgrey Cavefish, so there is no meaning behind them. Videocardz claims that AMD has developed Dimgrey Cavefish on its GFX103X graphics architecture, which will apparently be released as the RX 6500 or RX 6600.

By contrast, Navy Flounder will utilise the more powerful GFX1031 architecture for 40 Compute Units (CUs) and a 192-bit memory bus. According to Videocardz, AMD will sell Navy Flounder as either the RX 6700 or RX 6800 series, with the name RX 6900 reserved for Sienna Cichlid. So, it seems that AMD has at least three RDNA 2 GPUs in development. Frank Azor claims that AMD will no supply issues at launch, although that date may not correspond with the planned unveiling on October 28.
