A stunning top-corner strike from Miguel Almiron ensured Howe's team kept up their unbeaten top-flight record at St James' Park this calendar year.
The win also meant Newcastle moved up to 11th in the table and reached 40-mark with five games still left to play.
Howe said on matching Robson's record: "It's incredible because you're talking about an absolute legend of the football club – and quite rightly so.
"I never met him, but he was someone I always admired from afar for everything he achieved in the game.
"He is the benchmark, I think, around anything you try and do here – and it's great to have done that today."
On Miggy's moment
The Paraguayan match-winner has struggled for game time ever since Howe's arrival on Tyneside late last year, but has took his chance on his return to the starting lineup following Ryan Fraser's hamstring injury.
"He was excellent today, he really was," said The Toon head coach on Almiron.
"He's someone we've always liked.
"We had a team that's settled and doing very well – and he found it difficult to get in.
"That didn't change the way we think about him and he's had a chance now in the team."
Tonight's goal was the 28-year-old's first of the season.
"I thought his goal today epitomised his performance really. What a finish," claimed an ecstatic Howe.
"It's something he's worked really hard on behind the scenes, everyday on his finishing.
"He got his reward with that goal."
On a potential top 10 finish
Howe is not setting any targets yet though, however.
He told the media: "I think it’s just game-by-game.
It’s a very quick turnaround, with very little time to recover, but we’ll try and go to Norwich and win the game.
"We have a very difficult run-in. We were well aware of that all the way through the season that this run of games at the end was going to be a test.
"That's why it's great that we’ve got the points that we have at this moment."
