IIRC it's not just cores in general that do the computation, is it? Saturable reactors (https://en.wikipedia.org/wiki/Saturable_reactor https://en.wikipedia.org/wiki/Saturable_reactor) allow the use of magnetism for amplification, allowing one to build computers that would last a very very long time.
