Right, so the 7800X3D (due in April), the old 5800X3D, or any future threadripper or Epycs with the X3D.
Best L3 per core outside of the X3Ds it the 7600 or or 7900 CPUs that come with the full size L3 (32mb PER ccd) but only 6 cores per CCD (instead of 8).
There is currently no consumer model with 2 CCDs and X3D on both of them.
