The Intel Core i9-11900K was tested using using CPU limits imposed by Intel in the BIOS. The new Intel Core i9-11900K Rocket Lake processor topped out at 275 Watts in three runs of Cinebench R20. The Intel Core i9-10900K reached 283 Watts at the peak value in Cinebench R20 on the same exact motherboard. These two processors have the same TDP and when the Intel CPU limits are in place the power consumption is virtually the same.
