Mini-USB vs. USB4 2.0

Comparing 2 standards across 8 specifications. 8 key differences identified.

Comparing:
Mini-USB
USB4 2.0

Mini-USB (Mini-B) was a compact 5-pin connector common on digital cameras, MP3 players, and the original PlayStation Portable in the mid-2000s. USB-IF deprecated the Mini connector family in May 2007, and Micro-USB replaced it in nearly all subsequent compact-electronics designs.

USB4 2.0, released September 2022, doubles USB4's ceiling to 80 Gbit/s symmetric -- or an asymmetric 120/40 Gbit/s split favoring one direction for high-bandwidth uses like external displays. It requires new cables explicitly rated for the higher speed; existing USB4 v1 cables aren't guaranteed to reach it.
