The 8K@60Hz figure applies to a single display only; using two displays at once drops each to 4K@120Hz, and three or four displays drop each to 4K@60Hz. Each of the 4 ports can be independently configured as HDMI or DisplayPort. macOS/Mac lacks MST support, so multiple displays mirror instead of extending.
