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
motherboard-based CPU RAM is upgradeable, as well, whereas addon cards
tend not to offer this option.

He showed a die figure with 256GB of DRAM stacked 8-deep and 2×4-wide.
Then there is PCIe-CXL providing 1TB <of some kind of flash> you can
buy today. Plug and play. PCIe allows direct device to device transfers.
{GPU = 1 device, IE = 1 device, CXL-RAM = 1 device} all the CPU has to
do is program the I/O MMU to allow them to do their own thing, and deal
with the keyboard and mouse activities.
