A 3950x has 48 bits of virtual address space, or 256TiB.

I'm honestly not sure which counts for this purpose, physical or virtual? And which fraction do you get to use on HURD?

But still, 256 TiB is just a dozen drives these days. Not a very consumer-like configuration, but very much a limit you can run against.

48-bit virtual addresses are the most common in use today. All AMD, ARM64 processors, and most of Intel's. Only recent Intel chips support PML5 (5-level paging), giving them 57-bits of virtual address space. There are no 64-bit processors that can use a full 64-bits of virtual address space.
