Xbox 360 Does The Xbox 360 Slim play Original Xbox games better than the base xbox 360?

I've been buying and playing original xbox titles on 360 slim and was wondering if it played the games better or worse than a base model. Was curious and was hoping someone here knew the answer.

It uses the same processor. The only difference is it's thinner and uses 1 big fan instead of 2 small ones.
