This has no X3D, the L3 is shared between CCDs. The only odd thing about this is it has a relatively small "last level" cache on the GPU/Memory die, but X3D CPUs are still kings of single-threaded performance since that L3 is right on the CPU.
This thing has over twice the RAM bandwidth of the desktop CPUs though, and some apps like that. Just depends on the use case.
I'd wager a guess: AI?
Honestly CPUs are bad for AI, especially in this case where there's a GPU on the same bus anyway.
Of the top of my head, video encoding and compression/decompression really likes raw memory bandwidth. Maybe some games? Basically, wherever the M Pro/Max CPUs are really strong compared to the base M, these will excel in the same way.
