Yes, I have some of these cards and AFAICT the HBM2e chips just always run at full speed. I have different variants of the pcie cards and while I can get the gpu itself into a lower power state the memory just runs full tilt. Though I see 40w on my “normal” cards and 60w on the Frankenstein card that thinks it’s an sxm4.

IIRC this was one of the issues with 2/2e, some combination of the various available memory controllers not agreeing on a standard to manage timings and power states. I haven't played around with my Radeon VII in a long while now.

That aside idle power consumption is a driver-to-driver affair from both amd and novideo, sometimes I'm only pulling 15-30W when nothing is happening and other times it decides it needs 110w for a static 500hz screen
