Who had the higher IQ?
Reliable IQ figures aren't available for both. The richer comparison is what each accomplished and how it changed their field.

Different eras, different boards
The two were born roughly 87 years apart (1903 vs 1990), which matters: scientific tools, available knowledge, and intellectual culture compound. Comparing minds across eras is comparing players on different boards.
The verdict
So who was greater? The honest answer: they're not strictly comparable. By raw IQ proxy, John von Neumann edges out. By measurable, lasting influence in their respective field, both are anchors of the human record. If you have to pick one to bet civilization on, pick the one working on the problem you care about.
