If they bought the super computer with the goal of doing actual computation I really hope they know what they're getting themselves into. For example: if you just look at the clock speed and the cores you might think that you can calculate some kind of cost to do the work you need. But that would be extremely simplistic because the way CPUs work is so complex. CPUs have features that will execute certain work loads faster, that can cache certain instructions, and be more efficient with the same resources. So you might have CPUs that have a lower clock speed and core number that still blow older CPUs (that 'look better') out of the water.
It can be hard to know how well your CPU is going to perform with the instructions you generate until you have it tbh. You could get a sense of how fast it is compared to other processors with benchmarks. But I don't know how accurate it's going to be overall. A lot of the time you end up with unexpected results; CPUs that seem cheap are usually cheap for a reason though.
