With only one to two active cores, the processors can hit the ''Max Turbo''. However, anything in excess of two active cores, the processor drops to an ''All Boost'' frequency. For {{amd|Threadripper}}, the ''Max Turo'' was defined for 4 active cores or less and for AMD's {{amd|EPYC}} brand, the ''Max Turbo'' is defined for 12 or less active cores. |
With the introduction of {{amd|Precision Boost 2}}, the per-core definition was eliminated. Instead, the processor will automatically allow turbo for as many cores as the power budget allows. | With the introduction of {{amd|Precision Boost 2}}, the per-core definition was eliminated.
