He basically is able to see how data flows through code and can rewrite routines to ensure that as much is saved in the CPU's local caches (L1 / L2 / L3) as possible to optimize the calculations. In short, he's one of the best at writing code to minimize CPU cache misses and thus one of the best at writing blazingly fast code.
