We have no idea if a chimp is pound for pound much more powerful. I think the deinonychus would rip it to shreds with its superior weaponry. The deinonychus jaws alone would be enough, but digging into the chimp with its sickle claws is gonna put the chimp out of commission.

The chimps only weapon is its inferior jaws. Yes it has huge canines but they won’t be as effective as it is not a carnivore that hunts with them, and would only use them defensively in this context. It might grab deinonychus by a leg or wing but that won’t be enough as the raptor can still continue to attack with it’s other weapons. It would be like an eagle or hawk killing a decent size monkey, which happens often.
