Basically if the card is GCN 1 it supports Vulkan 1.0 GCN 2 and newer support Vulkan 1.1

It says 7640G

It does not support vulkan then all the 7000 series mobile APUs are TeraScale3 based.

I would be surprised that any gpu that doesn't support Vulkan actually supports DX12 correctly.

That's actually more common than you think. There are a lot more d3d12 compatible GPUs than Vulkan. Albeit at lower feature levels. But enough for dolphin.

Vendors put more effort into d3d12 support.

Well I guess I learned something new today

The 7000 series APUs really only see some of the CPU overhead benefits from DirectX 12 TeraScale3 is DirectX 11.3 SM 5.0 and not really a true DirectX 12 compatible architecture. Basically like Fermi for NVidia it is just a Pseudo DirectX 12 card and not really one.

Feature levels 11_0 and 11_1 (11.0, 11.1 and 11.3) do allow usage of D3D12 though...

That still requires SM 5.1 which is not included in TeraScale3 https://www.notebookcheck.net/AMD-Radeon-HD-7640G.69836.0.html

Though I was wrong about Fermi it has SM 5.1 support so is feature level 11_0.
