RDNA (microarchitecture)
RDNA (Radeon DNA) is a graphics processing unit (GPU) microarchitecture and accompanying instruction set architecture developed by AMD. It is the successor to their Graphics Core Next (GCN) microarchitecture/instruction set. The first product lineup featuring RDNA was the Radeon RX 5000 series of video cards, launched on July 7, 2019. The architecture is also used in mobile products. It is manufactured and fabricated with TSMC's N7 FinFET graphics chips used in the Navi series of AMD Radeon graphics cards.
The second iteration of RDNA was first featured in the PlayStation 5 and Xbox Series X/S consoles. Both consoles utilize a custom RDNA 2-based graphics solution as the basis for their GPU microarchitecture. On PC, RDNA 2 is featured in the Radeon RX 6000 series of video cards, which first launched in November 2020. RDNA 2 is also featured in Samsung's Exynos 2200 as the graphics architecture.
The third iteration of RDNA was announced on November 3, 2022, and is featured in the Radeon RX 7000 series of consumer desktop and mobile graphics cards.
The fourth and final iteration of RDNA was unveiled on January 6, 2025 at CES and is used in the Radeon RX 9000 series of desktop graphics cards.
AMD's GPUOpen website hosts PDF documents aiming to describe the environment, the organization and the program state of RDNA devices. They detail the instruction set and the microcode formats native to this family of processors that are accessible to programmers and compilers.
Documentation is available for:
RDNA 1 (also RDNA1) is the first implementation of the RDNA microarchitecture and is the successor to the Radeon RX Vega series. The launch occurred on July 7, 2019.
The architecture features a new processor design, although the first details released at AMD's Computex keynote hints at aspects from the previous Graphics Core Next (GCN) architecture being present for backwards compatibility purposes, which is especially important for its use (in the form of RDNA 2) in the major ninth generation game consoles (the Xbox Series X/S and PlayStation 5) to preserve native compatibility with their pre-existing eighth generation game libraries designed for GCN. It features multi-level cache hierarchy and an improved rendering pipeline, with support for GDDR6 memory.
