Clock Frequencies

The following chart shows how well the processor sustains its clock frequency and which boost clock speeds are achieved at various thread counts. This test uses a custom-coded application that mimics real-life performance—it is 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 modern AVX vector instructions. Each of the three test runs calculates the same result using the same algorithm, just with a different CPU instruction set.

Overclocking

Overclocking the Ryzen 5 7600 works exactly the same as on the -X suffix processors. Unlike Intel, AMD does not lock overclocking on these models, it's all there—unlocked multiplier, adjustable power limits, memory settings, everything.

For overclocking I dialed the voltage up to 1.35 V, which is about the maximum I could run Prime95 at and not overheat by crossing 115°C. I then dialed up the clocks until the system was unstable. While I could boot and run many lighter workloads, including games at well over 5.4 GHz, heavy loads kept crashing the system. Ultimately I settled for 5.3 GHz, which is a pretty decent overclock, considering a max boost rating of 5.1 GHz and 5.15 GHz actual max frequency at stock. With a decent AIO I feel you can probably get another 100 MHz, maybe more if you win the silicon lottery.
