With a PMG voltage is proportional to rpm. The ability to delivery current depends on such things as wire size, saturation of core etc. Voltage depends on the number of turns of wire, rpm and magnet strength etc.
Therefore it is impossible to tell from data supplied. It would however be very easy for you to test this.

Both turn at 500 rpm. Which motor would output more amps?
