I think it can, it's 32 bits at 720 or 500 MHz, and my main
reason for using it is because the collaborators
I found want it. That part of the design might be different on my
boards and theirs, or just do it the same for simplicity of
logistics, not for need. The logistics of making a working layout
and assembling these chips in BGA packages is tough to pull off.
I found a team of 2 working on it, so I've just helped by doing
some phone calling to get TI samples coming to spur us on in layout
drafting. We'll share some layout load. It's a boon.

Not sure about your terminology Nathan. The AM335x datasheet says,
for the ZCZ 15mm package:
EMAC (2-port) 10M/100M/1G
IEEE1588, and switch
(MII, RMII, RGMII)
You start with the MII interface, then add the PHY interface that has
transformers or other isolation. You want an OS to use ethernet -- it's
usable by the linux you boot on it.
The chip used in beagle bone design has two MII ports and does IEEE-1588
precision time protocol, which has an advantage for my field biologist customers
wanting to locate things by time of flight of sounds, etc.
We should probably leave the board design talk off this list though...
