Intel's Boyd Phelps showing off the company's new Tiger Lake CPUs fabbed on 10nm SuperFin.

Intel's Tiger Lake CPUs are going to be released soon but it turns out they have an ace up their sleeve when compared to Ice Lake. Unlike ICL, Tiger Lake CPUs are manufactured on the company's 10nm SuperFin process which allows 14nm-level clocks and other major architectural improvements. As it turns out, a Tiger Lake CPU can actually hit up to 5.0 GHz clocks - which is something that only Intel's most mature 14nm processes were able to do before.
