The confusion among users gets to the point where many think Precision Boost overdrive is a Precision Boost or simply a part of it, and in some cases there is a problem thinking that it is a technology that works in a similar way.
But the fact is that they are completely different: Precision Boost, Precision Boost 2 and Precision Boost Overdrive are three different algorithms, so today we'll try this last one very interesting.
Excessive overwork: excessive accumulation by hand is an old thing
PBO or Precision Boost overdrive It is a feature that was introduced in the Threadripper 2000 series and which, like those processors, sought a specific purpose: to improve multicore performance. To do this, AMD has set three important parameters (among many others): SoC Capacity (PPT Limit), Current VRM (TDC Limit) and Temp ° C.
The first is stated in watts and determines the amount of power the CPU can use before reaching the limit set by the Boost microcode. On AM4 prices are available 142 watts and 88 watts, depending on the CPU we install and its TDP.
The current VRM, meanwhile, is measured in amps and is the amount the motherboard can deliver to the processor before Boost mounts. Their numbers 95A and 60A respectively on the AM4, which will be selected according to the TDP of the CPU we are installing.
The temperature only measures the CPU to the limit when the Boost arrives and is set to the microcode.
The triangle of parameters will determine how the processor goes up outside of the Precision Boost 2 range, because unlike this, PBO is not enabled by default.
PBO vs Auto OC
This is also controversial, because people are also confused PBO by telephone OC car. And the fact that AMD doesn't provide much detail on how algorithms work together.
However, Lisa Su's company is meant to be used both at the same time, because Auto OC only benefits from a common increase in the same base, while PBO does it all, there are important differences.
The problem with the confusion comes because once we know the PBO the result is that the Auto OC raises the frequency of one context, so it's easy to understand why it's confusing.
Therefore, there are three programming elements that can be set up as AMD Out-of-Box, Manual OC and PBO + Auto OC, where the logic for starting stock mode on the motherboard, deactivates the Precision Boost 2 second for obvious reasons and the third configuration we talked about, which according to AMD 200 MHz over When conditions are right.
