To me it seems like the larger, more useful PCIe switches are basically at parity or exceed the cost of just buying a “bigger” platform, which definitely limits their appeal.
An entire current generation 80 lane Xeon or 64 lane Epyc CPU can be had for ~400USD, which is less than the cost of just the PCIe switch chip alone with no CPU functionality.
