In addition to the boost feature of the Ryzen 3000 processors, another AMD specific feature is called Precision Boost Overdrive or PBO. We set them to run at a resolution of 1920 x 1080 pixels and with the lowest graphics details available, so that our graphics card did not bottleneck the Ryzen 7 3700X. Keep in mind that there’s no guarantee that your chip will hit this increased boost clock or even the advertised boost clock (if the temp, power or voltage limits are breached). We could not add you to our newsletter. Again, it won’t go past the boost clock spec, and if the expanded headroom is still not enough (For example, the CPU is still running too hot), PBO won’t do anything. To see whether the processor performance is better or worse, we ran the same benchmarks three times: once with the CPU running at stock settings, once with PBO enabled, and once with PBO enabled and AutoOC set at an offset of plus 200 MHz. It increases the theoretical single-core boost clock of your CPU by up to +200MHz. I would like to see if there's any advantages to using Ryzen Master vs just enabling PBO in the BIOS. Precision Boost 2 was introduced with the 2nd Gen Ryzen processors. PBO means more electrical power going through your Ryzen processor, but only if it can handle it. Generally, PBO is useful with higher-end processors with 16 or more cores. Well, on paper the answer is rather straightforward. AMD’s Ryzen 3000 processors have a very sophisticated boosting algorithm, one that’s very sensitive to power and thermal spikes. In JetStream 2, a web browser benchmark that we ran in Google Chrome, enabling PBO and PBO + AutoOC meant the same thing: a small 1.35% increase in performance. This category only includes cookies that ensures basic functionalities and security features of the website. When the CPU hits one or more of these limits (PPT Limit, TDC Limit or Temp Limit), the boost clocks are scaled-down (throttling), regardless of whether the boost clocks (on spec) are met or not.eval(ez_write_tag([[300,250],'hardwaretimes_com-box-4','ezslot_2',122,'0','0'])); What Precision Boost Overdrive does is that it expands these limits, providing the processor with more headroom and opportunity to boost to the advertised clock. GD-135. However, when we enabled “Precision Boost Overdrive,“ the maximum boost frequency was lower at 4367 MHz, and when also turning AutoOC on, it was even lower, at 4342 MHz. Although you can get a one percent speed boost, more often than not, you’re getting less performance, In some games you get a few more frames per second, but in others you get fewer frames per second, Both the processor’s temperature and its power consumption increase, because of the higher voltages used. Archived. Precision Boost Overdrive is mainly useful for intensive workloads like content creation and rendering where all the CPU cores are utilized.
