Overclocking a CPU used to be a pretty simple process: change a bus speed or a multiplier, set an appropriate voltage, and voila: your Celeron 300A was running at 450 MHz, or your 600 MHz Duron was knocking on the 1 GHz barrier. These days with the advent of dynamic boost speeds and optimized frequency and voltage curves, processors intelligently push themselves up close to the limit straight out of the box. Setting a multiplier, even if it's higher than the base clock, might actually result in lower performance than stock speeds under certain conditions. The CPUs that likely have the most headroom, those a ways down the chain in Intel's lineup, for example, have locked multipliers and offer... Read more...
AMD introduced Precision Boost Overdrive, or PBO, a couple of years back to make extracting additional performance from its Ryzen processors, in systems with additional power and thermal headroom, as simple as a few clicks in Ryzen Master. And today, the company just updated the feature with a couple of new wrinkles to boost performance of Ryzen 5000 series processors even further. Unlike a manual overclock which can lock cores at a particular frequency, with Precision Boost Overdrive SenseMI is left in control of the processor, so frequencies and voltages can still dynamically scale up and down depending on the workload at the time. PBO monitors real-time environmental info from the processor... Read more...
