I think recommending people to to prefer {insert your favourite benchmark here} is very bad advice, and disproving your claim that Lemire's benchmarks are useless because YOU don't care about them is as simple as showing that they are useful for Lemire, which is something this post shows. If you care enough about a particular CPU to do benchmarks, you should benchmark what YOU care about. Lemire's job is to improve the implementation of particular algorithms to make optimal use of the hardware. Knowing the different theoretical hardware limits tells you how good an implementation is doing along different axes, and benchmarking those limits is a critical part of doing Lemire's job correctly. You probably have a different use case for computers than Lemire, and it is therefore completely reasonable for you to care about different benchmarks.
