Clock Frequencies

The following chart shows how well the processor is able to sustain its clock frequency, and what boost clock speeds are achieved at various thread counts. This test uses a custom-coded application that mimics real-life performance (not a stress test like Prime95). Modern processors change their clocking behavior depending on the type of load, which is why we provide three plots, with classic floating point math, SSE SIMD code, and using the modern AVX vector instructions. Each of the three test runs calculates the same result, using the same algorithm, just with a CPU different instruction set.

Overclocking

The AMD Ryzen 3 3100 has its multiplier unlocked, which means you are free to overclock it as you like—unlike Intel's non-K CPUs.

Overclocking was super easy, and we managed significant gains that greatly exceed what the default configuration is able to achieve. This is a first for Zen 2 because AMD usually clocks their processors right up to the maximum out of the box with clever boosting algorithms that pretty much nullify any manual overclocking potential.

At a very reasonable 1.25 V, the maximum CPU overclock was 4350 MHz. Higher voltage and AIO watercooling made 4.4 GHz mostly stable, but not fully.
