Support cpu model list encoder software method in gstreamer(not intel qs)

Hello.
I am interested in the minimum requirements for the processor in the software encoder task in MPEG-2, H.264, HEVC, AV1 formats.
Without using Intel Quick Sync.
Starting from which processors will it work, what support for processor instructions is required and other conditions?

On some machines I received the message:
“CPU ISA level is lower than required”
