AMD has finally ended support for its GCN GPU architecture which includes the Radeon 7000, 200, 300 & Fury series graphics cards. The aforementioned graphics families have now been moved to legacy status and no additional driver releases are planned for them.

In its official update, AMD confirmed that it has not only ended driver support for GCN GPUs but also moved Radeon software support for Windows 7 64-bit based operating systems to legacy. It looks like AMD has decided that it should now allocate its engineering resources to developing new and enhanced features for graphics products based on their latest architectures such as Polaris, Vega, RDNA 1, and RDNA 2.
