Chip positioning is different. The chip positioning of Raspberry Pie is an application processor, which can be used as a small server and nas at most, and has the ability of 1080p high-definition decoding (the Ethernet port and usb port of Raspberry Pie enjoy bandwidth, so the performance of nas will be very good); The performance of router is reflected in packet forwarding, traffic shaping and QoS. High-end router chips will add hardware to these operations, wireless chips and signal amplifiers, and even signal shielding, which are not comparable to the raspberry pie of a wireless network card.
