It should be roughly equivalent, yes. If rc6 is in fact the problem then
it is probably equivalent. You should try and see as we do set some

now we don't know what is going on.

You can come to #intel-gfx IRC channel and chat about it. We would like
to fix these powersaving issues and have been unable to reproduce most
of them locally.
