What is GPU Video Clock?

[cajux]

I searched everywhere but I haven't found any info.
What is GPU Video Clock?
How does it differ from the GPU Clock?
I have noticed that in idle GPU Video Clock is 405 MHz and GPU Memory clock is 202.5 MHz. Is it just a coincidence that GPU Video Clock corresponds to my effective GPU Memory clock?
Thank you

It's the clock of the video encoding/decoding engine.

The operating frequencies of the GPU nodes are dynamically changing depending on the task they considered so as to calculate the frame on time and to reduce the heating of the microcircuits as much as possible. Therefore, it cannot be said that "a knot ... through .... seconds will work with a frequency ...". Each GPU has several old -time sets of operating frequencies - minimum frequencies are used to work with text or simple static 2D pictures, medium -sized frequencies are used to work with video or more complex images, and the maximum ones for working with 3D scenes that are rapidly changing. These sets of parameters are set by the developer of the device, and with them, it calculates the cooling system.

So everything is very simple here. Numerically sets of working parameters for different GPUs differ, but their functional purpose is similar.
