WHAT WAS HE TALKING ABOUT ? is a complete interrogative sentence. That is, it is a question which if you ask, you are trying to find out the subject of “his” talk.

WHAT HE WAS TALKING ABOUT is actually a [noun] phrase. That is, it is not a complete sentence and you will use this phrase to say something about “his” talk to complete the sentence. For example, you can say What he was talking about IS IRRELEVANT TO OUR PRESENT DISCUSSION. Or, you can complete the sentence from the other end as well like, I DON’T REMEMBER what he was talking about.
