Both the base clock and max turbo clock are never reached with my Ryzen 3950X. It tends to run at about 4450 MHz single core and 4020-4220 MHz all cores. Mainboard is the marginally suitable Asus Prime B350-Plus, cooler Thermalright Macho Direct (for height reasons).

My point is: the official base and turbo clocks are not that relevant. Typical clocks can be found in product reviews.
