I use a laptop with intel HD 4000 and Radeon HD 8870M.
It seems radeon driver doesn't decrease power consumption and my machine runs at ~50C instead of ~40C if I switch itt off by acpi_call.

$ cat /etc/modprobe.d/radeon.conf
options radeon dpm=1 aspm=1 runpm=1 dynclks=1

# cat /sys/kernel/debug/dri/1/radeon_pm_info 
uvd    vclk: 0 dclk: 0
power level 0    sclk: 30000 mclk: 15000 vddc: 900 vddci: 900 pcie gen: 2
