So I think this is related as the new kernel driver can`t initialize the values
for the discrete card.
Please fix.

Thank you Alex for your engagement! Could you please include the patch in the
next 5.11.11 release so I could test the patch, sorry but I am not allowed to
compile a kernel on this machine.

Issue fixed in 5.11.12 even now it consumes less power (~1,07W less).

Before:

amdgpu-pci-0100
Adapter: PCI adapter
vddgfx:      756.00 mV 
edge:         +35.0 C  (crit = +94.0 C, hyst = -273.1 C)
power1:        8.14 W  (cap =  60.00 W)

After:

amdgpu-pci-0100
Adapter: PCI adapter
vddgfx:      756.00 mV 
edge:         +38.0°C  (crit = +94.0°C, hyst = -273.1°C)
power1:        7.07 W  (cap =  60.00 W)

Thank you!
