The Performance & Power Efficiency Of The Core i7 990X vs. Core i9 9900K

The Performance & Power Efficiency Of The Core i7 990X vs. Core i9 9900K: With my initial Core i9 9900K benchmarks out there following Friday's embargo expiration, for some weekend benchmarking fun I decided to pull out the old Core i7 990X to see how it compares to the new 9900K... The Gulftown and Coffeelake processors were compared not only on raw performance but also overall power consumption and performance-per-Watt.
