The 9700K's max single core turbo is 4.9 GHz....; best all-core loadings should hit 4.6 GHz, if cooling is adequate and there are no power limitations imposed. (Perhaps Intel's XTU will at least allow overruling the turbo-boost duration limit and power/TDP limits even with a B360 so you can at least possibly see sustained all-core 4.6 GHz...which is PLENTY for most mortals, save for bragging rights, sounding impressive, etc.,perhaps)
