Developers have confirms Vulkan support for Radeon 7000 series before the official announcement.
Taken from Videocardz … The Vulkan 1.3 specification released in January this year is now widely supported by AMD, NVIDIA, and Intel GPUs. The recently launched GeForce RTX 4090 GPU supports the newest 188.8.131.52 implementation, and it appears that Radeon RX 7000 desktop GPU will have similar support as well.
A brief look at the conformance list shows that almost all modern graphics, including NVIDIA GeForce RTX 30/40 and Intel Arc A-series, now support the latest 1.3 standard. AMD has recently confirmed that ‘undisclosed products’ based on RDNA3 GPU family has successfully completed Vulkan 184.108.40.206 conformity test suite. Support for this graphics API is confirmed for Ubuntu and Windows 10.
The company has not said anything about RDNA3 support for other APIs, such as DirectX12 Ultimate. However, Radeon RX 6000 series already support this API and there is nothing newer on the horizon.
AMD Radeon RX 7000 series are to be unveiled on November 3rd. The company is set to showcase their enthusiast RX 7900XTX and RX 7900XT graphics cards based on Navi 31 GPU.
