It's hard to make a direct comparison because the range of strength and muscle mass ranges wildly, but bodybuilders can have a lot more muscle while powerlifters and strongmen can be significantly stronger despite having less overall muscle mass. Strongmen and powerlifters don't necessarily need to be heavier to outlift a bodybuilder.
An example comparison of two elites at the top of their game would be 8x Olympia Champion Ronnie Coleman
and multiple world record holding powerlifter Kevin Oak.
I chose these comparisons because they're both 5'11" (180cm) in height. They're both elite and world class in their respective sports. And it was easy for me to find stats.
Right off the bat, you can see that Ronnie has a lot more muscle. On stage he was between 285-300 lb (~130-135kg) and probably ~5% body fat. That means he had roughly 15 lb (7kg) of fat with about 280 lb (130kg) of lean mass. In his off-season he was about 320 lb (145kg).
Kevin Oak on the other hand competes in both the 220 and 242 class. Based on the photos he is maybe around 10-15% body fat. This puts his lean mass at best around 200-220.
Despite being almost 100 lb lighter, Kevin squats as much as Ronnie ever has. What this shows is that specialized training can make the muscle you have considerably stronger. The reason Ronnie isn't stronger is because that was not where his focus was. His training was designed to maximize mass, not strength. Likewise, Kevin's training is designed to maximize strength (specifically in squat, bench, and deadlift).
There is of course carryover. Building muscle mass will undoubtedly make you stronger. Being stronger will undoubtedly create muscle mass. Though depending on the training style, one will advance faster than the other.
