AMD "Zen 3" Testé avec la vitesse de rampe de vitesse d'horloge plus rapide que les SoC Snapdragon

AMD’s "Zen 3" architecture, particularly in its low-power mobile iterations, change their clock speeds at a very high rate of speed (switching between lower idle clock-speeds to higher boost clock bins), finds a study by Chips and Cheese, which tested 17 processors across brands and machine-architectures, including mobile SoCs. The interesting finding here is that the Ryzen 7 5800U "Zen 3" mobile processor has a much faster speed-ramp than even SoC powering handhelds, such as the Qualcomm Snapdragon 821, returning a ramp-time of just 1.6 Mme, par rapport à 19.6 ms on the Snapdragon. We now see why AMD likes its processors to run detached from the 10 ms tick-rate of Windows internal power-management (the rate at which the OS reports its workload to the processor, so it could respond with a higher performance state). A rapid boost clock ramp rate allows the processor to better ration its power budget in response to workload.
