I'm just confirming the issue over TB4 on a Lenovo Z13 laptop and RX 7600 XT in an eGPU setup using the same kernel parameters as workarounds (amd_iommu=3Doff instead). It never pulls more than ~50 watts and maybe ~20= 00MHz on the GPU and ~400 MHz on the VRAM. --=20 You may reply to this email to add a comment.
