USB 3.2 Gen 1 vs. USB Power Delivery
Comparing 2 standards across 8 specifications. 8 key differences identified.
Comparing:
USB 3.2 Gen 1
USB Power Delivery
Originally released as USB 3.0 in November 2008, this 5 Gbit/s "SuperSpeed" tier was retroactively renamed USB 3.2 Gen 1x1 when the USB 3.2 specification arrived in 2017 -- the first step in a naming scheme many found more confusing than clarifying, since the underlying hardware and speed never actually changed.
USB Power Delivery (USB PD) is a separate negotiation protocol governing how much power flows over a USB-C cable -- independent of the cable's data speed. Standard Power Range tops out at 100W (20V/5A); PD 3.1's Extended Power Range (2021) raised that ceiling to 240W (48V/5A), requiring cables with a built-in identification chip.
