AMD’s new Ryzen 7 2700X and Ryzen 5 2600X already overclocked to 5.88 GHz on all cores by a user named “TSAIK”. Which demonstrating the improved overclocking headroom AMD achieved by switching to the newer 12nm process.
The 2700X achieved 5884 MHz with a 58.25X multiplier on a 101.02 MHz base clock with a 1.76V core voltage.
On the other hand, the 2600X has reached 5882 MHz with the same 58.25X multiplier on a 101 MHz base clock, and a slightly higher 1.768V. Both chips have all their cores and SMT enabled. The 2700X was overclocked on the MSI X470 Gaming M7 AC, while 2600X was overclocked on an MSI X470 Gaming Plus with a single 8 GB G.Skill Trident-Z DDR4 module. Both CPUs was cooled using liquid nitrogen evaporator. So we should expect better-overclocking headroom than current Ryzen CPUs.
