we only know that he is uber strong and fast
All that is known of the Raikage's abilities is super human strength, not unlike that of the current Hokage, Tsunade so it is therefore possible that he is a skilled taijutsu user like Tsunade. At his introduction he smashed a stone table while holding some huge weights in the other hand without any difficulty. He also seems to be very powerful, seeing as he deflected the Eight-Tailed Beast which was sealed inside his brother at the time. He is also very fast as Killerbee said he was faster than him while using hachibi chakra.
