The way I gather from it RHulk would have one. One of the Hulk's problems is sometimes he takes awhile to build his strength up. If he can be overwhelmed before that happens he is in trouble. To me what seemed to be happening was RHulk was doing to GHulk what WWHulk did to Wolverine faster than GHulk's healing factor could keep up. (Remember, his healing factor has been given a much needed tune down since WWH.)

Thor intervened and had RHulk on the ropes. (Why RHulk was suddenly being effected by his blows I do not know.)

This gave GHulk a chance to recover and get mad that not only was RHulk beating him again, but long hair was saving him and proving to be stronger. This made him mad enough and gave him enough time for his strength, durability, and healing factor to rise to a level where he could withstand RHulk better. RHulk meanwhile was worn down due to his fight with Thor and getting hotter. Like a reactor reaching its limit RHulk might start out stronger and even get a bit stronger, but he has lower limit in which he can grow and once he reached it GHulk was able to ko him. At least that is what I got.

In short, RHulk stars off with a higher base strength and durability than Hulk. This level is about equal if not superior to guys like Thor and a traditional enraged savage Hulk. He may or may not be able to get stronger, but if he can it is not by much and when he taxes himself he quickly reaches a limit due to internal temperature.

Savage usually starts at a lower strength level, but through anger can get higher with a limit about Thor level if not a bit higher. (I know hulk fans will say he has no limit, but theoratically he can only get so angry and he seems to have lost whatever strength gains he had from the explosion on Sakaar.) Hulk's durability and healing allow him to last longer periods of time.
