Furmark is an inappropriate benchmark because it just sends a shader that gets spammed endlessly by the GPU and isn’t link limited at all. Scores are practically identical to the mean for those devices.
Steel Nomad is probably more accurate. It’s a really simple level, so I’m not sure to what degree objects are being streamed in and out. For reference, 4090s seem to pull 95FPS on Steel Nomad where mine was 84FPS.
