These first-generation chips were built on the 14 nm FinFET fabrication process and included the 1950X, which was the first 16-core consumer-grade AMD APU. AMD followed this in April 2018 with nine Ryzen processors built on the new Zen+ architecture, including the Ryzen 7 2700X and the Ryzen 5 2600X. Zen+ is built with 12 nm processes, which should bring significantly better performance with the same power consumption as last year’s Ryzen APUs. The new Threadripper APUs also benefit from improved cache latencies and turbo boost functionality. These second-generation chips implement Extended Frequency Range 2 (XFR2) and Precision Boost 2 (PBO), the combination of which should allow the APUs to graduate their clock frequencies as more cores are used. This should mean that these new APUs can maintain turbo clock speeds for longer than last year’s chips.
