You put a video of a guy running cinebench ST? u know why? because it doesn't work for MT.
"Curve optimizer, in and of itself doesn't alter voltage, it alters the boost frequencies at a given voltage. If frequency is capped via something else, then yes, voltage will also go down, but if allowed, voltage will scale normally and boost speeds will increase with the larger negative offsets." CO does not lower the voltage if you have CPU voltage set to AUTO, it will only means that it will use the same voltage for MT unless you manually change that, you would usually under good conditions get "higher" clocks as the negative magnitude will tell the CPU that it can actually do same voltage for higher clocks. This applies good for ST and that's why when you run MT cinebench the CPU will have throttle the clocks to keep stability, but power draw will be the same. I think you believe that CO is some kind of off set to Vcore which is not. Then for MT your only way to cool down temps is to limit PBO values below default. That would impact temps on MT because regardless of Vcore, the CPU won't be able to draw full amps and power under MT load, heating less. If you set CO -30 all cores and expect MT cinebench to run at top peak clocks, that won't happen, and it will still draw power since you haven't limited PBO values.
