Amdgpu monitoring "path"

I know this might be a silly question. But why is the path of my GPU(RX6800) /sys/kernel/debug/dri/**1**/amdgpu_pm_info instead of of /sys/kernel/debug/dri/**0**/amdgpu_pm_info as it is mentioned in the Arch Wiki? I only have 1 GPU and my CPU doesn’t has integrated graphics. I’m just curious.
