Ports + - Upstream TB3 40Gbps 85W PD (for TB3 host)   or USB-C 10Gbps 85W PD (for USB-C host) - Downstream TB3 40Gbps DP1.4 15W (for TB3 device) - Downstream USB-C USB 2.0 15W (for USB-C device) - DisplayPort 1.4 - USB-C 10Gbps 5V/1.5A - USB-A 10Gbps 5V/900mA x 2 - USB-A 5Gbps 5V/900mA x 3 - USB-A QC 3.0 18W - Gigabit Ethernet - MicroSD/SD 4.0 UHS-II 312MB/s - Digital Coaxial Audio - Optical Toslink Audio - 3.5mm Audio Jack - DC 180W   Features + Thunderbolt 3 Titan Ridge Latest version of Thunderbolt 3 utilizing Intel Titan Ridge chipset which supports backward compatibility with USB-C non-TB3 devices. Supports 8K Dual & Triple 4K Video Output Supports dual (8K+4K) video (Mac/PC) or triple 4K video (PC/Chrome only with MST hub). See supported max video resolutions below. Daisy Chain up to 6 x TB3 Devices Daisy chain up to 6 x Thunderbolt 3 docks or devices. Compatible with USB-C Host Backward compatible with USB-C (non-TB3) host/computer. The difference between TB3 vs USB-C connection would be upstream bandwidth (40Gbps vs 10Gbs) downstream port (TB3 vs USB-C 2.0) and video resolution (see below). All other port features remain the same. Upstream TB3 40Gbps 85W PD When connected to TB3 host/computer Upstream TB3 port supports 40Gbps data bandwidth and 85W Power Delivery to TB3 host Upstream USB-C 10Gbps 85W PD When connected to USB-C (non-TB3) host/computer. Upstream TB3 port supports 10Gbps data bandwidth and 85W Power Delivery to USB-C host Downstrem TB3 40Gbps DP1.4 15W When connected to TB3 host Downstream TB3 port supports 40Gbps data transfer DisplayPort 1.4 video 15W power and ability to daisy chain up to 6 x TB3 devices. Downstream USB-C USB 2.0 15W When connected to USB-C (non-TB3) host/computer. Downstream TB3 port supports USB 2.0 data transfer and 15W power. DisplayPort 1.4 Supports DisplayPort 1.2 and 1.4 protocols. Connect to a single DP display (Mac/PC/Chrome) or MST hub to expand up to 3 extended displays (PC/Chrome only) 6 x USB High-Speed Data Ports USB-C 10Gbps 5V/1.5A USB-A 10Gbps 5V/900mA x 2 USB-A 5Gbps 5V/900mA x 3 USB-A QC 3.0 18W Charging Port Charging only.
