The article is looking at it all wrong. To solve a problem, start by looking at those that already solved it. Then, see if you can apply that. Mainframes have long had ridiculously high utilization and throughput. Secret is their I/O architecture: computing happens on compute nodes and I/O is managed by I/O processors, both of which are well-integrated. If Intel etc copy this, they'll get much higher utilization and throughput. Smart embedded engineers do the same thing albeit with microcontrollers.
