I don't think that was the point of these benchmarks. Instead it is interesting to see how memory bandwidth effects CPU performance.

M.L. was benchmarking various standard Phoronix tests on the same CPU core in three different 16-core configurations: one that was asymmetric with fast cache, one with the highest per core TDP, and one with lower peak clocks but a fast "inter-CCD" (TBF, I'm not sure they qualify as CCDs in the 395) connect and high memory bandwidth.
While I've always disliked the way M.L. does their overall "geometric mean", each of the three configurations performed favorably on a subset of the tests, which implies that more than just TDP was tested.
These benchmarks are measuring TDP not memory bandwidth.
