Encoding and protocol efficiency vs vnc or rdp

[dlukt]

Both VNC and RDP were developed for remote management.
I have an old Intel NUC, Windows installed, which I connect to via RDP, and the quality is great.
I haven't monitored the consumed bandwidth.
Likewise I have a remote dedicated Linux server running TigerVNC, because it provides hardware acceleration, which is necessary for OBS (video broadcasting software) to work without system load spiking to high amounts, because of near 100% CPU load.
The remote server has an embedded GPU.
The picture is clear, like with the local RDP connection and low latency.

Then, I installed Rustdesk on the NUC machine.
It uses h264, so hwencoding, but even on quality, the picture quality is not as good as with RDP.

I have another machine where I installed Rustdesk on the local network on Windows. It has a nv4070.
And my main machine has a 5080, so both are capable of h265 encoding and decoding.
The quality is great.
I have not measured bandwidth consumed vs vnc or rdp.

Then sunshine exists, which is for game streaming, but could also be used for desktop management, however it has increased bandwidth requirements, if you'd like a good picture quality. x264 requires about 16MBps iirc, where h265 requires about 12MBps, and AV1 about 10MBps.
