Radeon RX 5000 series

The Radeon RX 5000 series is a series of graphics processors developed by AMD, based on their RDNA architecture. The prefix "50" has been speculated to be AMD celebrating its 50th anniversary in 2019. The series is targeting the mainstream mid to high-end segment and is the successor to the Radeon RX Vega series. The launch occurred on July 7, 2019. It is manufactured using TSMC's 7 nm FinFET semiconductor fabrication process.
Architecture.
The Navi GPUs are the first AMD GPUs to use the new RDNA architecture, whose compute units have been redesigned to improve efficiency and instructions per clock (IPC). It features a multi-level cache hierarchy, which offers higher performance, lower latency, and less power consumption compared to the previous series. Navi also features an updated memory controller with GDDR6 support.
The encoding stack has changed from using Unified Video Decoder and Video Coding Engine, to using Video Core Next. VCN was previously used in the GCN 5th generation (Vega) implementation in Raven Ridge, though not utilised in other Vega product lines.
Vulkan (API).
Vulkan 1.2 is available with Adrenalin 20.1 and Linux Mesa 20.0 for GCN 2nd Gen. or higher for RDNA.

Physical characteristics.
The dimensions of modern graphics cards frequently exceeds the dimensions specified in the PCIe standard. Particularly, no card model fits in the specified height limit of 107 mm.
