According to details provided by the developer, you'll need at least an Intel Core i5-6600 or AMD Ryzen 5 1600 CPU, 12GB of RAM, and either a Radeon RX 580 8GB or Geforce GTX 1060 6GB graphics card to play the game.

The recommended requirements kick off with Intel Core i7-8700 or AMD Ryzen 5 3600 CPU, 16GB of RAM, and either an AMD Radeon RX 5700XT 8GB or Nvidia Geforce GTX 1080 Ti 11GB graphics card.

The game needs 12GB of VRAM for 4K at Ultra settings

During AMD's RDNA2 online event, and as a part of the partner showcase, Counterplay Games showed off Godfall, which will support DirectX 12 Ultimate, and as noted in the video below, worked closely with AMD to implement DXR 1.1 raytracing, Variable Rate Shading, as well as AMD Fidelity FX.

In the same showcase, Counterplay Games says the game actually needs a high memory bandwidth as well as 12GB of VRAM to run the game at UHD 4K resolution 4Kx4K textures and at Ultra settings. This works in AMD favor as AMD's entire Radeon RX 6000 series SKUs come with 16GB of VRAM, while Nvidia RTX 3080 comes wiht 10GB of VRAM. Of course, there is the flagship RTX 3090 with 24GB of VRAM, but that is a whole different market and price segment.

In any case, Godfal launches on November 12th on the PC and is actually one of the first games confirmed for release on the Playstation 5, which also launches on November 12th.
