Question Is the 7950x3d a 7800x3d+?

[FreeBee101]

I may not have looked close enough(nor do I know how to.), but is the 7950x3d a 7800x3d core with a 7950x core next to it? Did they use the good 7800x3d cores to make the 7950x3d's first?

If 7800x3d is an 8 core and 7950's are all 16 core's with two dies... Or is the 7800x3d a double 4x die?

7950x3d is 8+8 cores (two dies)
7900x3d is 6+6 cores (two dies with 2 cores each disabled due to manufacturing defects)
7800x3d is 8+0 cores (single die)

how they bin it? no clue
perf/voltage targets i guess
