This was only true for Epyc, and only true for a small number of low CCD SKUs.
Consumer platforms do NOT do this; this has actually been discussed in depth in the Threadripper Pro space. The low CCD parts were hamstrung by the shortage of IF links, meaning that they got a far smaller bump from more than 4 channels of populated RAM than they could have.
Ah, interesting and disappointing. I've been looking for more memory bandwidth. The M4 max is tempting, even if only half the bandwidth is available to the CPUs. I was also looking at the low end epyc, like the Epyc Turin 9115 (12 channel) or Siena 8124P (6 channel). Both in the $650-$750 range, but it's frustratingly hard to figure out what they are actually capable of.
I do look forward to the AMD Strix Halo (256 bit x 8533 MHz).
