CPU core count does translate to performance gains but the popular software architecture idioms most people use are incapable of taking advantage of large numbers of cores. The gap between the performance you typically see and what is possible with proper software architecture and performance engineering is orders of magnitude in scale. A lot of performance and scalability is left on the table. We've known how to scale software on large silicon for a long time, but as an industry we mostly can't be bothered (or lack the skills) to do it.
