Does thor have enough power to defeat thanos without the infinity stones?

The only verified information concerns the function of the Infinity Stones and Thanos’s use of them to wipe out half of all life. No source in the evidence describes a confrontation between Thor and Thanos that occurs without the Stones, nor does it compare Thor’s power level to Thanos’s in such a context. Therefore, based on the facts given, we cannot determine if Thor has sufficient power to defeat Thanos without the Stones.
