Hear me out! I know we had this theory before!
Thanks to The Silt writeup on FIT and VFT curves, i finally understand AMD have made Ryzen 3000 closer to GPU boosting than old Intel Turbos.
The biggest problem with initial testings, the reviewers did not fully unclock the PBO motherboard limits!
Which being the PPT, TDC and EDC limits of your motherboard to supply unlimited powah to Ryzen 3000.
Back to the VFT curve, volt, freq and thermals.
Zen2 follows a strict VF curve, depending on chiplets, every cores can only run at x'Ghz with y'Volts, at certain temp. Go past that thermal mark, it will drop a multiplier or more.
As such you see core temps are the ultimate decisions at how long you can boost to. Sure say a 3950X can boost to 4.7Ghz at 1.45v, but without strong cooling, it wil not sustain for long.
So to keep thermals down, you can use super chiller cooling or you live in sub 20c ambient or you simply undervolt it! Hear me out again!
Now consider how small the 3000 IHS is, how small 7nm is, to dissipate heat with a regular WC is tougher than ever0! Again thanks to Silt, who calculated the heat density, regular WC and regular ambient are not conducive enough to remove heat fast! The key word is fast!
So now with undervolt, your VF curve shift downwards, so you go from 1.45v to 1.4v, and your boost clocks drops to 4.65Ghz. However, your temps are down 5-8C, which means 4.65Ghz is able to sustain longer!
Back to the bolded, now try with PBO on, +200Mhz, and unlock your PPT/TDC/EDC values, return all LLC to default vdroop. Disable PBO Scalar too.
The goal is to lower voltages as much as we can, while supplying as much current and power the CPU can accept.
Don't worry the FIT inside the chiplets will maintain stability of lowered voltages and the safety levels of current it can absorb!
On assumption you already have a good cooling solution, say a Noctua or 240mm AIO
Be prepared to be surprised!
Set vcore to 'normal', and offset -0.05v for start.
vcore LLC to 'normal'
soc LLC to 'high', if you are overclocking ram, else normal
Set the edc in CBS/XFR to 155. tdc to 125. ppt to 185. scalar to 1x.
In Amd overclocking menu, there is PBO handoff to 'motherboard' and autoOc settings to +200
