yesterday received my rx 7900 xt nitro+
office work 4k@60 via hdmi
set up custom resolution, selected CVT reduced blanking (and reset driver via cru-1.5.1 / restart64.exe)
traced for some hours with gpu-z 2.52.0 and 0,5s sampling while doing office work.
average power draw ~26W. (significantly more than my short-time replacement rx 6600 - but ok, that one is unbeaten in idle power consumption)
here the distribution (x .. watts, y .. occurrences in trace):
- it seems gpu idles between 20-22 watts
- whatever actions in my office work pull the draw ~ +15 watts
YET, interestingly the GPU-Z's active tracing is keeping the GPU voltage up&down.
when I have only the adrenalin perf view opened, the GPU voltage is then quite stable around 110mV and the TBP is steady at
17W
I can just conclude that
* adrenalin 23.1.1 at least fixed the idle 4k@60 single monitoring mem clock that stays very low
* rx 7900 xt is quite sensitive about polling some values of it, which kicks the GPU voltage (it's like quantum world where observation affects the system)
