The "insane" RAM bandwidth makes sense with Apple M chips and Strix Halo because it's actually "crap" VRAM bandwidth for the GPU. What makes those nice is the quantity of memory the GPU has (even though its slow), not that the CPU has tons of RAM bandwidth.
When you go to the desktop it becomes harder to justify including beefed up memory controllers just for the CPU vs putting that towards beefing some other part of the CPU up that has more of an impact in cost or performance.
