![]() Remember that in addition to these three power limits PB is constrained by temperature and max boost clocks, and these limits are not affected by PBO.ĪMD has been extremely reluctant to commit to numbers for single core boost and all core boost, because Precision Boost uses an “opportunistic algorithm” to boost frequency until it hits one of those limits. ![]() 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. At best it will allow the CPU to maintain boost clocks longer and more often, and therefore PBO will have the strongest effect on scenarios where the CPU is already able to boost. The effect on CPU clock speed is indirect, and PBO will never boost the CPU past the advertised clocks. What is important to note is that PBO only affects these three power limits.
