video playback will likely kick the asic out of idle. What’s your power use at true desktop idle?

Generally speaking, vega 10 (56, 64) and 20 (radeon vii) are able to achieve decently low desktop idle with varied display configs due to the memory technology they employ.

Can you tell us which distro and display config this is with?

I’m also in 3D_FULLSCREEN on NV21XT but my idle mclk is 96 MHz. TGP (not to be confused with TBP which is only communicated on RDNA 3 and up) is 6 watts at idle with my browsers open. GNOME 47 + Wayland, 2560 x 1440 @ 180Hz + 1920 x 1080 @ 60Hz, VRR enabled on both displays. This is with Fedora 41, kernel 6.13.6-200.fc41.x86_64

For context, the GPU index (0,1,2 etc) will depend on the number of video adapters you have in the system. If you have a CPU with integrated graphics, there’s a chance this will be registered as 0000 whereas the dGPU will be 0001.

tech can be tasty too :)

I have a similar memory of when I was young, overhearing my older brother and my uncle talking about chips. I thought they were talking about oven chips (fries elsewhere in the world). They were talking about the semiconductor industry. All I could think about was yummy yummy carbs.

On an unrelated nore, I now work in the semiconductor industry.

in the UK we call them microcrisps
