Intel's new Adaptive Boost technology will allow the Rocket Lake S Core i9-11900K and 11900KF to hit 5.1 GHz on all eight cores

Intel recently unveiled yet another boost technology set to debut exclusively on its top-tier Rocket Lake S i9-11900K CPU. Adaptive Boost will allow the processor to hit up to 5.1 GHz on all cores, assuming cooling is up to snuff and temperatures are below 70 degrees C.

Intel recently unveiled a new, exclusive clock boosting technology for its top-tier Rocket Lake S Core i9-11900K and i9-11900KF, called Adaptive Boost. Adaptive Boost will work alongside Turbo Boost and Thermal Velocity Boost. When temperatures are below 70 degrees, Adaptive Boost will help the top-tier Rocket Lake S silicon hit 5.1 GHz on all cores, and up to 5.3 GHz on two cores. 

This would mean that the i9-11900K will be able to manage significantly better all-core boost clocks than the i7-11700K, without any "actual" overclocking. If a great cooling solution is in place, the i9-11900K will potentially hit 5.1 GHz on all cores with no additional tweaking. 

The i7-11700K hits just 4.6 GHz on all cores, which is a bit lower than the Comet Lake S i7-10700K. Rocket Lake S's IPC improvements weren't quite enough to translate into meaningful gains in gaming workloads, with Comet Lake occasionally beating out the newer part. On the other hand, a 5.1 GHz all-core clock could give the 11900K the edge it needs. Considering the fact that it's an eight-core part replacing the 10-core i9-10900K, Adaptive Boost becomes even more important to close the gap.
