Slight overclocking or using AVX-512 instructions is enough
Intel Rocket Lake-S processors came out and turned out to be quite good. At least many of the early performance leaks indicated significantly lower performance.
Core i9-11900K can draw about 400W without extreme overclocking
However, the new items use the good old 14-nanometer process technology, which could not but affect energy consumption. As shown by our own tests, the Core i9-11900K consumes as much under load as the 10-core Core i9-10900K. However, this is far from the limit.
As tests have shown, under certain conditions, the power consumption of the new Intel flagship can reach or even exceed 400 W! For example, in the Prime95 AVX benchmark, the new CPU consumes 394W, which is due to the AVX-512 instructions. In addition, MSI found that after the 5 GHz mark, every additional 100 MHz is given to the processor at the cost of an impressive increase in power consumption.
With the transition from 5.1 GHz to 5.2 GHz, power consumption increases immediately by 60 W, reaching 378 W already in ordinary applications, and not in specialized benchmarks. That is, those who want to overclock their CPU will have to purchase a very powerful cooling system.
