The Pi 3 has 100Mbit Ethernet, whereas the Tinker Board boasts Gigabit Ethernet. However, both offer just 802.11n WiFi not 802.11ac, 4 x USB 2.0 ports rather than USB 3.0, HDMI video output, an audio minijack, a 40-pin IO header, and two 15-pin serial interfaces, one for camera (CSI) and one for display (DSI). The Pi 3 has Bluetooth 4.1 but the Tinker Board Bluetooth 4.0. So ASUS is trying to match the Raspberry Pi 3 for connectivity and peripheral compatibility, whilst trumping it on the performance of the underlying hardware.
