Why? It comes down to RAM. Those addon processors will never have access
to the sheer quantity of RAM that is available to the CPU. And

Marvell already offers a CXL add-on processor card that supports
up to 4TB of DRAM with 16 high-end ARM64 V series cores.

At somewhere near 3× the latency to DRAM.
If the size works for your application--great !
If the latency does not work for you--less great.
