G400D built in Ethernet vs ENC28

I am a little bit confused with the built-in Ethernet and ENC28 Ethernet on the G400D module (just the module). Are they the same? or they are different hardware with noticeable performance differences? Which one has better performance and is recommended to use?


The ENC28 chip provides ethernet support via an SPI interface. The builtin support connects directly to an ethernet connector.

Look at the JD11 and the ENC28 Gadgeteer modules, in the catalog, for details on the connection methodology.

I would assume that the G400D built-in ethernet has higher theoretical performance, but I don’t have hard data to back that up. In the real world, however, your throughput will likely be limited by the NETMF interpreter long before those kinds of considerations come into play.
