Last time I tried matrix (~2022) they still didn't have voice channels--they had voice calls but not a mechanism where people can join/leave a particular voice chat at will. To me this is a must have feature for anyone who has used discord/mumble/ventrilo.
I dont think apple silicon supports SMT? Isn't that enough evidence to show at least for mobile parts 4P4E at least has a chance to be interesting? Also some of the graphs appear to show the new Skymont uarch has high perf/w than raptor cove (the previous P core) which is rather impressive in my opinion.
