I didn't want to have to deal with the non-uniform CCDs. Of course the two on a 7950x aren't uniform either due to silicon lottery (eg on mine the first CCD clocks 100MHz higher than the other on all-core load and 200MHz higher on single-core load), but that is a small difference. It would presumably be more pronounced on the 7950x3d since only one has access to the extra cache. So I would be using it "sub-optimally" if I didn't `taskset` / cgroup everything to run on one CCD or the other.
