Intel introduces Adaptive Boost Technology for Core i9-11900K and Core i9-11900KF
The 11th Gen Core series codenamed “Rocket Lake-S” will get a 4th Boost mode, labeled Adaptive Boost. Both Thermal Velocity Boost (TVB) and Adaptive Boost Technology (ABT) will be exclusive to Rocket Lake’s Core i9-11900K(F) series.
And read it well, specifically the 11th Gen Core i9 Series. And yes, that means Core i9 Rocket-Lake will have four tiers of Boost modes. A bit confusing, we agree. But I'll try and explain it.
Three of the now four modes you are likely familiar with; there's Turbo Boost 2.0 and 3.0, and then Thermal Velocity Boost (TVB). Add to that Adaptive Boost Technology (ABT), which is a boost state applied to all cores (!) if certain power supply and if the cooling requirements are met. We're not sure yet how conditions for a PSU are measured but we'll leave that open for now.
Adaptive Boost will only be available for the Core i9 K and -KF models: In other words, only Core i9-11900K and Core i9-11900KF. With a processor temperature of less than 70°C, it achieves a Thermal Velocity Boost of 5.3 GHz on two cores. That's 5.2 GHz without TVB. If more than two cores are working, a maximum of 5.1 GHz is possible, but so far only for up to four cores if TVB activates. So four cores max.
Adaptive Boost now takes it up a notch, if a proper power supply is applied, and if temps remain below 70 Degrees C, all eight cores can boost to 5.1 GHz. So for more than four cores the up to 5.1 GHz far exceeds the previous specification of 4.9 or 4.8 GHz.
You'll need the latest BIOS revisions to get this supported. You can see where this new Boost feature would help, multi-threaded apps and games.

I think for benchmarks this will be a huge difference.
I hope this will be available in z490 and 500 series chipset

From the image in the article, only TVB is constrained to a 70°C limit, the other three are noted as having 100°C limits.
In the Article you have it as 70°C also for adaptive boost
Adaptive Boost will only be available for the Core i9 K and -KF models: In other words, only Core i9-11900K and Core i9-11900KF. With a processor temperature of less than 70°C, it achieves a Thermal Velocity Boost of 5.3 GHz on two cores. That's 5.2 GHz without TVB. If more than two cores are working, a maximum of 5.1 GHz is possible, but so far only for up to four cores if TVB activates. So four cores max.
Adaptive Boost now takes it up a notch, if a proper power supply is applied, and if temps remain below 70 Degrees C, all eight cores can boost to 5.1 GHz. So for more than four cores the up to 5.1 GHz far exceeds the previous specification of 4.9 or 4.8 GHz.

Does this have any advantage over just setting all cores manually to 5.1?

Hmm interesting. I hope that this will be looked at with the reviews, quite curious to see if that actually does make a difference in regards to different workloads (boosting higher in gaming, more average boost across 4 cores when doing calculation workloads etc).
