AMD Navi 21 6nm

AMD's Navi 21 6nm GPU uses the RDNA 2.0 architecture and is made using a 6 nm production process at TSMC. With a die size of 520 mm² and a transistor count of 26,800 million it is a very big chip. Navi 21 6nm supports DirectX 12 Ultimate (Feature Level 12_2). For GPU compute applications, OpenCL version 2.1 can be used. Additionally, the DirectX 12 Ultimate capability guarantees support for hardware-raytracing, variable-rate shading and more, in upcoming video games. Unknown texture mapping units and Unknown ROPs. Due to the lack of unified shaders you will not be able to run recent games at all (which require unified shader/DX10+ support).
