The 3900X is a very efficient CPU but it can suck down a huge amount of power (and generate a lot of heat) when asked to - up to 140W in default settings. The first thing that you will notice when you run Cinebench is that your temps will be a lot lower - and this is what we will exploit (in the system I was working with this was a difference of 10° - 13° C). You'll notice that the preset PBO settings (PBO Enabled) result in lower voltage and clocks frequencies with the Taichi. Because one of the constraints is thermal, PBO will also have less effect on CPUs that are already well-cooled and not bumping up against that limit. With the launch of the Ryzen 3000 series processors, we’ve noticed a distinct confusion among readers and viewers when it comes to the phrases “Precision Boost 2,” “XFR,” “Precision Boost Overdrive,” which is different from Precision Boost, and “AutoOC.” There is also a lot of confusion about what’s considered stock, what PBO even does or if it works at all, and how thermals impact frequency of Ryzen CPUs. Precision Boost Overdrive or “PBO” works the same as Precision Boost 2. Once It hit 1.325V or so on my processor, it stops boosting. Note that I don’t recommend 3600 – 3533 or a bit less seems to work better. The limits that it’s raising aren’t limits that are restricting performance. We’ll quote directly from AMD’s review documentation so that there is no room for confusion: Package Power Tracking (“PPT”): The PPT threshold is the allowed socket power consumption permitted across the voltage rails supplying the socket. We’re careful to use the same high-quality NZXT X62 liquid cooler on every CPU we test with the fans and pumps at max speed to avoid any throttling, eliminating the thermal variable, but if we weren’t or if a reviewer were less scrupulous, performance would be directly affected on Ryzen 3000 chips based on the cooler used. Click on all the cores in CCD0 and CCD1 and set them to a speed and test that. Please us Ryzen Master to view your cores. Please post a picture of your test results if you can or cannot get your 3900x to boost to 4.6 on any core. The single core result for "Profile 2" was 480 which was exactly the same as using the Auto Overclock option on Ryzen Master, the big difference however it achieved that score at 1.3 Volts (whereas the Auto Overclock resulted in the CPU having 1.45 Volts shoved into it) and the PPT (CPU) value was at around 16% whereas with the Auto Overclock the PPT (CPU) wall all the way in the red at 100%For "Profile 1" the single core result was a bit over 490 (can't remember exactly) but again the voltage was at 1.3 Volts and the PPT was again at around 16%Especially with the single core results in Cinebench both Precision Boost Overdrive and Auto Overclocking options were punting ridiculous amounts of volts into the CPU for an inferior score.With regard to the all core results, with PBO and Auto Overclock the CPU had an all core boost of just a bit over 4.0 GHz and a score of 6385. He knows me and was thus willing to allow me to use Teamviewer to access his system, and was willing to spend the time with me to allow me to do the job right (which took over six hours of configuring and testing). Go. Motherboard manufacturers could triple PBO limits tomorrow (if they’re even the ones that control those numbers) and it wouldn’t make a difference based on what we’ve seen. When we installed a 3600 in our MSI Godlike, we got the 65W numbers; when we installed a 3900X, we got the 105W numbers. AMD showed a 21 point increase for 1t performance in this test, we showed a 12 point increase; we can’t tell you a percent difference for AMD’s numbers because they omitted a vertical axis on their marketing charts, attempting to render them as useless as possible.
