Well, the code that was published alongside the article is written in Python and CUDA, so you're not looking at the right kind of processor to start. My 5-year-old, consumer-grade GPU does 1.5 MHz * 2300 cores, whereas the equivalent released this year does 1.7 Mhz * 8900 cores. Granted, not the best way to measure GPU performance, but it is roughly keeping pace with Moore's law, and it's going to be a better indicator of the future than Intel CPU capabilities, especially for machine learning applications.
