Yet again this depends on battery voltage. If both motors are geared to produce the same speed and are in the same vehicle with the same batteries, you would have to gear the 12xl higher than the 8xl and it would load the battery and esc more. The 8xl will draw more current, than the 12xl will if they are both spinning the same rpm. The 8xl is generally run with 4 or 5s lipo, and the 12xl would be good with 6-7s lipo. They will have similar output (watts), but the higher voltage system will draw less current (amps)

Both motors can produce the same amount of torque. But the 8XL needs more amps to reach the same level as the 12XL. The 8xl has fewer winds and thus generates a weaker magnetic field when feeding the same Amps. Theoreticaly a 2500kv motor will need twice the Amps as the same motor with 1250kv to generate the same amount of torque.
