There’s a base and boost clock, but what do these numbers mean?
What Is CPU Boost?
It’s enabled by default on all devices.

The base clock is the clock speed at which the CPU runs under light loads or when idle.
The CPU frequency can even drop below the base clock if you have one of the power-saving technologies enabled.
The exact opposite of CPU boost isthermal throttling, which slows your processor down when it gets hot.
Most programs and games today use more than one core.
CPU boost can dynamically increase the clock speed of multiple cores to achieve optimal performance depending on the workload.
They might use different algorithms, but the outcome is comparable.
Should You Turn CPU Boost On or Off?
CPU boost provides a substantial performance boostwithout the need for an overclock.
“Who in their right mind would want to turn off CPU boost?”
is probably the question running through your mind right now.
While that’s a valid question, there are a few scenarios where turning off CPU boost makes sense.
Another legitimate use case is for handhelds.
What Is AMD Precision Boost Overdrive?
PBO increases the motherboard’s power limit threshold.
In other words, PBO allows your processor to consume more power and generate more heat.
It’s an easy way to increase your CPU performance with minimal risk.
Turning Precision Boost Overdrive on will void your CPU warranty.
So unless you have a good reason, leave it alone, and enjoy that sweet free performance.
