Depends on the workload: Analytical DBs are often I/O limited.

  Modern consumer SSDs are what, 2GB/sec, DDR4 is 60GB/sec. What kind of CPU can process data at these speeds?

    Isn't the cache going to be in the 100GB/s range? Why would we even have a cache if memory speed wasn't a bottleneck.

      That's not the point. Even trivial meaningful data manipulations are not possible at such speeds. Maybe on some 18-core Xeons, and even then I doubt it.
