Early AMD Ryzen 4000 'Vermeer' Desktop CPUs seem to feature some impressive clock speeds as the latest report from Igor's Lab suggests an even higher boost frequency for the flagship Ryzen 9 4950X processor.

Yesterday, Igor reported that he has spotted the Zen 3 based Ryzen 'Vermeer' desktop processor which he believes to be the flagship Ryzen 9 4950X. The engineering sample spotted yesterday was running at speeds of up to 4.8 GHz but the latest sample features even higher base & boost clocks which are just a 100 Mhz short of the 5 GHz mark.
