Who had the higher IQ?
By the most cited estimates, Garry Kasparov tops this matchup with an estimated IQ of 190, a 0-point margin over John von Neumann (190). IQ estimates for historical figures are reconstructions, not test results — they sit on top of biographical evidence, productivity, and the difficulty of the problems each person solved. Treat the number as a directional signal, not a verdict.

Different eras, different boards
The two were born roughly 60 years apart (1963 vs 1903), 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, Garry Kasparov 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.
