At the beginning of this year, it was announced by the Khronos Group the specifications for the Vulkan 1.3 API. While some graphics card companies immediately jumped onto Vulkan API support through their in-house drivers, several GPUs were absent due to release dates and setbacks. Intel did have their UHD and Iris Xe iGPUs offering support for Vulkan 1.3. The Arc Alchemist mobile GPU line is now present, providing support for the current API.

Now that the Arc Alchemist series, also known as the Intel Xe-HPG line, is present with Vulkan 1.3 API support, we continue to wait for the desktop Arc series to appear on the Vulkan 1.3 support. The following graphics cards from the Intel Arc line are currently on the Khronos Group website: A350M, A370M, A550M, A730M, and A770M. Interestingly enough, the A350M, A370M, and A730M are currently available, while we are still awaiting the A550M and A770M to the support list.
