It's a very pretty benchmark. Everyone has the same basic objective and measurement norm, so we can see how performance improves year over year, and how different manufacturers handle a specific known goal, even if it's not super-representative of real world use cases. Billion-dollar supercomputers don't spend most of their time running LINPACK, and some probably perform better on specific tasks, but it doesn't make the Top 500 list any less of a thing.
