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.

While everyone should take Intel claims and marketing slides with a grain of salt, do people really think they are going to flat out lie about their 11900k claims? It is their most binned SKU and people are really downplaying the role of their AI/DL Boost stuff for workflow applications.

Who started this myth? It's not even true. AMD or Intel, almost same power usage...

Well these new ones aren’t on there. And this chart is gaming which usually doesn’t tax the CPU. We will see when the full review is out. I expect the review to be... hot lol

intel is still very efficient for a lot of home/gaming pc usages
it's that max stress test power draw with avx on that's utterly ridiculous.
but yeah,I don't think people who choose ryzens over intel for home rigs because of power savings realize this
idle
video playback
gaming
all values are for the whole system w. rtx2080
here's a great test,albeit in Polish,telling you exactly what every tasks costs in energy

you won't learn this from memes or youtube trash
this is power draw for every minute of the cpu sitting in idle

Well gaming may vary a lot, depending if you are gaming vsync off uncapped or vsynced.
I can imagine a game like witcher 3 is playing with vsync.
I do not know the details of that review, but yes, amd and intel haven't totally different power consumption on normal gaming.

Yeah, for sure! Upgrade from CL? I mean downgrade. XD
