Well, the claim that:

It has a greatly improved GPU feature set with much faster input/output, due to
the incorporation of a PCIe link that connects the USB 2 and USB 3 ports, and a
natively attached Ethernet controller.

is very encouraging, but the scarcity of numbers makes me wonder if the
benefits are useful.
