While it’s totally open to criticism that Intel once again postponed its 10nm desktop PC and launched Rocket Lake-S in 14nm, the truth is that it’s as much a subject of discussion and criticism as it is laudable. the fact that each time the frequencies increase higher with the same node. Yes, at the cost of a little more energy, it is true, but the step which is mounted compensates for the first increase at the expense of the temperature, how do they do?
Intel Adaptive Boost technology, one more step to increase speed
Currently and if we understand more or less how Intel architectures for processors work with reference to frequency, we will know that at this time and until the departure of Rocket Lake-S with Cypress Cove as the base microarchitecture, there were three ways to increase frequency. to the nuclei.
These modes are Turbo Boost 2.0, Turbo Boost 3.0 (launched at Haswell for HEDT) and Thermal Velocity Boost (TVB, launched on 9 Gen Mainstream). Well, if these modes weren’t enough to boost and optimize frequencies per core group or individually, with Rocket Lake-S and only i9 processors of this architecture, we will have a new mode: Adaptive Boost Technology or ABT.
Why launch a new technology that increases the frequency when there is already another one that does? Because Intel gave TVB one more spin. And the point is that the restriction or limitation (let’s call it what everyone wants) of TVB is that it was limited to a single kernel, which it is not currently.
Intel resets thermal and power limits to increase speed
Only two models will have ABT: i9-11900K and i9-11900KF, which as we already know will be able to drive up to two 5.3GHz cores with TVB. But where does ABT come in? From three hearts. Intel states that if a suitable power source can be applied and the temperatures are below 70 degrees Celsius, from 3 cores the frequency of both processors can be increased to 5.1 GHz.
It’s hard to figure out, so let’s take it in parts. Up to 2 cores, the frequency will reach up to 5.3 GHz thanks to TVB, in three cores, ABT and TVB will alternate to bring them to 5.1 GHz, which is also repeated when loading 4 cores.
After loading 5 cores, TVB will only reach 4.9 GHz, while up to 5.1 GHz ABT will be responsible for reaching this frequency. Six cores follow the trail of 5 cores with the same values, but when loading 7 and 8 cores, TVB will only reach 4.8 GHz in all cores and to overcome this speed ABT will have to come into play to reach up to ‘at 5.1 GHz on all cores.
According to Intel, the latest BIOS versions will be needed for this to be compatible, what we understand will be standard on motherboards that should already reach retailers, because otherwise we will have to be vigilant and update them as necessary. In any case and we repeat, these speeds will only occur when the power options are adequate (see table above) and the processor temperature is below 70 ° C.
