I have pretty good garden hose pressure, way better than average. The incoming water supply pipe is 1" and the pipe for the garden faucet comes right off the main line. It's literally just around 6 feet of pipe from the main line to the outdoor garden faucet, so minimal pressure drop at the garden faucet from the city supplied line.
We lucked out. Most of my neighbourhood has 3/4" supply pipes, or even just 1/2", so 1" is an anomaly in my neighbourhood.
