Who had the higher IQ?
By the most cited estimates, Alan Turing tops this matchup with an estimated IQ of 185, a 15-point margin over Charles Babbage (170). 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.
Achievements compared
Alan Turing is best known for: Cryptanalysis of the Enigma • Turing's proof • Turing machine • Turing test • Unorganised machine • Turing pattern • Turing reduction • The Chemical Basis of Morphogenesis Charles Babbage is best known for: Originating the concept of a digital programmable computer.

Different eras, different boards
The two were born roughly 121 years apart (1912 vs 1791), 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, Alan Turing 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.
