As pointed out by others, motors vary in efficiency. My Unisaw runs a three horse, but idles along at about seven amps. The collector connected to it is also a three horse, but idles at fifteen amps. Some of that may be load, but some of it may be the motor quality too.

The foregoing aside, I just pulled a one horse Delta off my miter and replaced it with the HF “two horse.” We, normally, don’t run more than a horse and a half on a o120 circuit. That would be a lot of amps and reduced efficiency. That said, I note a HUGE difference in how much dust is collected, even with just a hose near the output of the miter. I can only imagine what it’d do with a five inch hose.
