In boxing, you will generate more power by throwing with your non blocking hand and, generally speaking. More torque, more energy, you're also typically on the balls of your feet, not always rooted as many styles of TCMA promote. Boxing is all about footwork and the stances are much narrower. The punches tend to be more compact...I'm just comparing to CLF. Obviously you can use boxing style punching in TCMA. When sparring in CLF I added hooks, I love that strike, its not traditional Kung Fu but very effective.
In TCMA you generate power from your hips, dan tien, and rooted feet. In boxing you pivot generating your power shoulders and arms. You can see it in fighters physiques.
Also with TCMA, attacking with two hands or sticky hands is important for applying locks, throws and the like and boxers are never concerned with that. Maintaining contact with your opponent is something I think some TCMA emphasizes over boxing. Boxing and TCMA do have similarities with strategies...attacking at different levels, breaking down structure, deception, distance, counter attacks etc.
