Prior to their debit next week, Khronos Group has announced Vulkan 1.3 support for AMD's RDNA 3 GPU-based Radeon RX 7000 series graphics cards.
Khronos Group Adds Vulkan 1.3 Support For AMD's Next-Gen RDNA 3 "Radeon RX 7000" GPUs
As discovered by Videocardz, the Khronos Group conformant page now lists AMD's RDNA 3 GPUs which are ready to support the latest Vulkan 1.3 API. The latest version of the Vulkan API, v1.3.3.1, will be supported by the upcoming Radeon RX 7000 series graphics cards and the respective Navi 3X GPUs powering them.
Recently, NVIDIA's GeForce RTX 4090, the flagship of the Ada Lovelace lineup, also got Vulkan 1.3 support so that means both GPU companies have their next-gen lineups ready for the latest APIs. The AMD RDNA 3 "Radeon RX 7000" GPUs have received Vulkan 1.3 API support in both Ubuntu 64-bit and Windows 10 64-bit operating systems.
AMD confirmed that its RDNA 3 GPUs will be coming later this year with a huge performance uplift. The company's Senior Vice President of Engineering, Radeon Technologies Group, David Wang, said that the next-gen GPUs for Radeon RX 7000 series will offer over 50% performance per watt uplift vs the existing RDNA 2 GPUs. As we've seen each generation, AMD's upcoming GPUs will be ready to support the latest and greatest of APIs on various operating systems. Some of the key features of the RDNA 3 GPUs highlighted by AMD will include:
- 5nm Process Node
- Advanced Chiplet Packaging
- Rearchitected Compute Unit
- Optimized Graphics Pipeline
- Next-Gen AMD Infinity Cache
- Enhanced Ray Tracing Capabilities
- Refined Adaptive Power Management
- >50% Perf/Watt vs RDNA 2
AMD will be unveiling its RDNA 3 GPU architecture and the Radeon RX 7000 graphics cards on the 3rd of November. They have a full Livestream planned which you can read more details about here.
