The 'Magpies' only striker in the squad was Joselu with Dwight Gayle on the verge of joining West Brom, but the Spaniard was ineffective in front of goal as has become expected of him.
There were some impressive performers among the ranks of Benitez's side, with Ayoze Perez and Matt Ritchie testing Andreas Luthe in the opposition goal, but nothing got past the Augsburg keeper.
Some of the summer signings that the manager has managed to bring in made an appearance, with Kenedy starting the match while Ki Sung-yeung and Fabian Schar came on from the bench as the game progressed.
Midfielder Mo Diame went down injured at the half hour mark, which led to Ki's introduction, but it is unclear the extent of his injury.
With Augsburg's first shot on target of the game, Michael Gregoritsch headed in the only goal of the game 12 minutes in to the second period, leading Newcastle fans to voice their frustration at the club's ownership.
The game generally reaffirmed what Newcastle fans and Benitez alike knew already, that the squad desperately needs a goal threat.
All will be hoping that the addition of forward Salomon Rondon from West Brom will be confirmed soon enough for him to play in the side's first game of the Premier League season against Tottenham Hotspur next weekend.
