They're getting 200GB/s transfer rates for the on-die memory. It takes four DIMMs to total that much memory bandwidth on DDR5.
However, swapping to modular RAM has to be more performant than swapping to SSD. I don't know why they don't offer the option in at least the pro model. Sure, they have to add something to the kernel to handle two layers of swap, but that can't be too bad.
There's no reason in principle that you couldn't do this. Just stick a bunch of RAM on a PCIe bus and provide a driver that exposes it as a memory-mapped device under
I wonder if recompiling the FreeBSD swapctl command would make it possible to just add a huge swap file on such a device. Depends on whether they've kept the same syscall hooks under the hood, I guess.
