HDMI was designed by the entertainment industry to connect HD televisions. Its initial version was electronically basically half of a DVI connector, with some audio data thrown into the video stream. Plenty for a 1080p 60Hz stream, but not much beyond that.

DisplayPort was developed by VESA for computer use. It supported a higher bandwidth than HDMI and rapidly gained support for features like variable refresh rates, compression, and feeding multiple monitors through a single cable.

Nowadays it doesn't really matter that much, and they both essentially have the same capabilities. It's now HDMI for televisions and DP for computers because History.
