The most profitable process node in the history of Intel has been its 14nm process. Since 2014, the company has been pumping out CPUs built on a variety of configurations of its 14nm – slowly optimizing for power and frequency. We used to call these variants 14+ and 14++, but as the next process node isn’t yet ready, rather than draw attention to a soon-to-be 6-year old process, Intel just calls it all ‘14nm class’. The latest launch on 14nm is Intel’s new Cascade Lake-X processors: high-end desktop hardware that gives a slight frequency improvement over Skylake-X from 2017 but it also has the first round of hardware mitigations. Today we’re testing the best CPU of the new list, the Core i9-10980XE.
