Radeon RX 5000 series

The Radeon RX 5000 series is a series of graphics processors developed by AMD, based on their RDNA architecture. 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 utilized in other Vega product lines.

Vulkan (API)
Vulkan 1.2 is supported with Adrenalin 20.1.2 and Linux Mesa3D 20.0.0.

Vulkan 1.3 is supported with Adrenalin 22.1.2 and Linux Mesa3D 22.0.0.

Resizable BAR support
PCIe Resizable BAR (RBAR, branded as Smart Access Memory, SAM) is supported with Adrenalin 21.9.1 or higher.

This feature (first available on RX 6000 series) is now supported on RX 5000 series GPUs.

Comparison of 5700 XT models
Comparison of non-reference Radeon RX 5700 XT model video cards, from the AMD Radeon RX 5000 series. 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.
