GPU-Z Cayman log playing a Youtube video
I used GPU-Z under Windows to monitor mclk, sclk, VDDC and temperature.
Temperature was pretty much the same as the one I had under Linux.
However, power levels are different.
First, under Windows, anytime the memory goes above the default mclk speed
(150MHz), VDDC is set to 1.063V even if the GPU is not running at full speed.
Under Linux, VDDC is set to 1.060V only if both mclk and sclk are running at
full speed. Otherwise, VDDC is kept at 1.000V. Why this difference?
Next, there is an intermediate power level where sclk runs at 500MHz and mclk
runs at 650MHz with a VDDC at 1.063V. Even when running in 1080p, it never went
above that speed. Under Linux, the intermediate power level (power level 1)
uses a sclk at 500MHz (same) and mclk at 1300MHz (twice as fast, the same as
the maximum power level 2) with only a VDDC of 1.000V.
There was no indication about the VDDCI.
