The forward has only made one substitute appearance under his new manager; however, he was unavailable for the Arsenal fixture due to an injury.
With transfer links to West Bromwich Albion, the Magpies boss has clarified the status of the striker, who has yet to score a goal this season.
Howe stated: "What I have seen is someone who can certainly score goals, is a brilliant finisher. I think he has got real competition because I think Callum (Wilson) and Dwight are very similar players, in a sense that they both lead the line. They both like to play centrally.
"So it is great to have two experienced players in that position, and two players who certainly know where the goal is. Dwight will have an important role. He is very well respected by the group and a well-liked member of the team. I am going to enjoy working with him, for sure."
Gayle did not feature this weekend as the Magpies were able to secure their first victory of the season against Burnley.
