Power consumption regression in NVIDIA Linux drivers 465.27 [cannot reproduce]

I cannot be absolutely sure if it’s a regression only in NVIDIA drivers, and not due to the fact that I’ve also upgraded Linux 5.11 to 5.12 but here’s what I have now:

Idle power consumption
NVIDIA drivers 465.27/Linux kernel 5.12.X: 10.3W
NVIDIA drivers 465.24/Linux kernel 5.11.X: 8.5W

Everything else is exactly the same.

I’m running Fedora 33 with all updates installed, XFCE with no compositing.
My monitor (1440p, 144Hz) is connected via DisplayPort.
My GPU is GTX 1660 Ti, running at stock, no overclocking.

My nvidia.conf

Section "Device"
    Identifier  "Videocard0"
    BusID       "PCI:7:0:0"
    Driver      "nvidia"
    VendorName  "NVIDIA"
    BoardName   "NVIDIA Corporation TU116 [GeForce GTX 1660 Ti] (rev a1)"
    Option      "Coolbits" "28"
    Option      "metamodes" "nvidia-auto-select +0+0 {ForceCompositionPipeline=On, ForceFullCompositionPipeline=On}"
    Option      "UseNvKmsCompositionPipeline" "Off"

I cannot reproduce it currently. Let’s mark it INVALID for a while.
