There are switch chips with varying capabilities. For example, this is not something you'll see in an 8-port switch for home use:I don't know - some give the impression that they can but you might know better. As I say, they're all built aroud the same chips...

Of course, switching throughput isn't the only metric that matters. For example, smaller/cheaper switches are likely to have more limited MAC address memory. That has no impact in a typical home use case with one computer per port (if that). Connecting lots of such switches together in a multi-layered tree might not work out so well.
